In the Kanter’s and Kinsella’s works is proposes the use of two synchronized artificial neural networks (SANN) connected by opening communication channel to confidential formation of a common cryptographic key. At the same time, there are few questions of practical suitability of this technology for cryptographic applications. There are no recommendations on the choice of parameters of the used networks, ensuring acceptable speed and guaranteed confidentiality of the generated general secret.In this regard, it is interesting to substantiate the rational values of the parameters of ANN from the point of view of cryptographic requirements and security analysis of the proposed method of formation of cryptographic keys.

Cryptographic protection in information and information and communication systems is an important component of cybersecurity. Therefore, the development, research and improvement of means of cryptographic information protection is an urgent and important task. In this paper, we study evolutionary methods for generating non-linear substitutions (S-boxes). These are cryptographic primitives that are an important component of many modern block and stream ciphers with a secret key. However, the problem of generating random highly non-linear substitutions is extremely difficult. In this paper, we study the annealing simulation method. This is an iterative algorithm, the essence of which is the gradual improvement of the current solution (substitution). Special cost functions are used as an improvement criterion. The initial state is formed randomly, and then, at each iteration the current solution is gradually changed. Approaching the target solution means minimizing the cost function. The paper investigates a simple and computationally efficient cost function based on the Walsh-Hadamard transform. Through exploratory research and numerous tests, it was possible to optimize the operation of the annealing simulation algorithm. Optimized algorithm for several parameters (initial temperature, "cooling factor", cost function) allows you to quickly generate highly non-linear bijective substitutions for cryptographic applications. Compared to other well-known implementations of the annealing simulation algorithm, the use of the recommended parameters can significantly reduce the generation time of nonlinear substitutions.

The aim of this work is to study the algorithms, the stability of which is based on the search for a short lattice vector, as well as to obtain time-resistant parameters of these algorithms. Existing methods for generating keys and choosing parameters for cryptographic transformations on algebraic lattices resistant to time attacks are considered. It is shown that the uniform distribution of coefficients for generating the NTRU algorithm keys has certain shortages, namely, a limited number of parameters suitable for use in cryptographical transformations. This is due to the vulnerability of this algorithm to time attacks. The possibility of using a discrete normal (Gaussian) distribution to form a key pair, which will prevent the sensitivity of the algorithm to time attacks, is considered. This method of generation requires checking the obtained sample for compliance with the properties of the normal distribution. The usage of SAGA tests has been proposed. They make it possible to check the Gaussian samples obtained using the discrete normal distribution. The verification result shows whether or not the sample has properties that are inherent in the normal distribution. The application of the SAGA statistical tests to the NTRU cryptographic transformation polynomials allowed us to conclude that the discrete Gaussian sample makes it possible to generate time-resistant parameters using the norm or the length of the short basis (vector) of the lattice as the mean-square deviation.

Quantum cryptography is used to find practical and useful applications. Recently, some first quantum cryptographic solutions became available on the market. For clients, it is important to be able to compare the quality and properties of the proposed products. To this end, one needs to elaborate on specifications and standards of solutions in quantum cryptography. We propose and discuss a list of characteristics for the specification, which includes numerical evaluations of the security of solution and can be considered as a standard for quantum key distribution solutions. The list is based on the average time of key generation, depending on some parameters. In the simplest case for the user, the list includes three characteristics: the security degree, the length of keys and the key refresh rate.

For a security system built on symmetric-key cryptography algorithms, the substitution box (S-box) plays a crucial role to resist cryptanalysis. In this article, we incorporate quantum chaos and PWLCM chaotic map into a new method of S-box design. The secret key is transformed to generate a six tuple system parameter, which is involved in the generation process of chaotic sequences of two chaotic systems. The output of one chaotic system will disturb the parameters of another chaotic system in order to improve the complexity of encryption sequence. S-box is obtained by XOR operation of the output of two chaotic systems. Over the obtained 500 key-dependent S-boxes, we test the S-box cryptographical properties on bijection, nonlinearity, SAC, BIC, differential approximation probability, respectively. Performance comparison of proposed S-box with those chaos-based one in the literature has been made. The results show that the cryptographic characteristics of proposed S-box has met our design objectives and can be applied to data encryption, user authentication and system access control.

Blockchain technology is a game-changing, enhancing security for the supply chain of smart additive manufacturing. Blockchain enables the tracking and recording of the history of each transaction in a ledger stored in the cloud that cannot be altered, and when blockchain is combined with digital signatures, it verifies the identity of the participants with its non-repudiation capabilities. One of the weaknesses of blockchain is the difficulty of preventing malicious participants from gaining access to public–private key pairs. Groups of opponents often interact freely with the network, and this is a security concern when cloud-based methods manage the key pairs. Therefore, we are proposing end-to-end security schemes by both inserting tamper-resistant devices in the hardware of the peripheral devices and using ternary cryptography. The tamper-resistant devices, which are designed with nanomaterials, act as Physical Unclonable Functions to generate secret cryptographic keys. One-time use public–private key pairs are generated for each transaction. In addition, the cryptographic scheme incorporates a third logic state to mitigate man-in-the-middle attacks. The generation of these public–private key pairs is compatible with post quantum cryptography. The third scheme we are proposing is the use of noise injection techniques used with high-performance computing to increase the security of the system. We present prototypes to demonstrate the feasibility of these schemes and to quantify the relevant parameters. We conclude by presenting the value of blockchains to secure the logistics of additive manufacturing operations.

In recent years, there has been a significant amount of research related to the development of quantum computers. If such a computer were to be built, it would be able to break existing public-key cryptosystems that are currently used for many purposes. This will seriously affect the privacy and integrity of digital communications, etc. That is why special attention is currently being paid to post-quantum cryptography, the main goal of which is the development of cryptographic systems that are protected from both quantum and classical attacks, and will also be able to interact with existing communication protocols and networks. In view of the significant importance of the practical application of directional encryption algorithms, at the international and state level, special attention was paid to the implementation of the proposed requirements for key encapsulation protocols. Key-establishment algorithms (KEA) form a common secret – the key for a symmetric encryption algorithm. The paper considers two KEA algorithms that use algebraic lattices: one of the finalists of the 3rd round Crystals-Kyber and the Skelya algorithm (DSTU 8961-2019). The Kyber algorithm first performs asymmetric encryption of a 32-byte message, and then generates a shared secret. The Skelya algorithm performs the same actions, but for asymmetric encryption, it uses messages of any length that do not exceed the maximum possible. That is why the last algorithm can be used not only as a KEA algorithm, but also as an asymmetric encryption algorithm. According to the NIST Security level, the Kyber algorithm provides cryptographic 1, 3, and 5 security levels, and the Rock algorithm provides cryptographic 3, 5, and 7 security levels. The cryptographic stability that is ensured for both algorithms is determined by a set of parameters. Thus, the purpose of this work is to review the details of the implementation of each of the mentioned algorithms, to compare the speed of the key generation, encapsulation and decapsulation algorithms for the Kyber and Skelya algorithms in terms of key data lengths, and the encapsulation result and computational complexity of both algorithms.

In cryptography, Block ciphers use S-Boxes to perform substitution and permutation operations on a data block. S-Boxes provide non-linearity and confusion of bits to the cryptographic algorithms. In addition, secret keys are critical security aspects for encrypting and decrypting messages. The uncertainty and randomness of the secret key and S-boxes used in the algorithm determine the extent of security against any cryptanalysis attack. This paper proposes a new mechanism to dynamically generate a secret key and S-Box each time while sending and receiving the message. These dynamically generated S-Boxes and keys depend on mutually decided security parameters and message transfer history. Furthermore, a new counter-based mechanism is introduced in this paper. These enhancement techniques are applied to the serpent cipher algorithm, and a data transfer simulation is performed to validate the efficacy of the proposed method. We observe that the dynamically generated S-box follows the strict avalanche criteria. We further validate that the encrypted message shows higher sensitivity to the S-box and the secret key in enhanced serpent cipher than the original version. However, to validate our proposed method, we test and analyze the improvements in the Serpent Cipher Algorithm.

Dans ce travail, nous analysons des certificats SSL/TLS X.509 (utilisant le chiffrement RSA et provenant de centaines de millions de matériels connectés) à la recherche d'anomalies et étendons notamment les travaux de Hastings, Fried et Heninger (2016). Notre étude a été réalisée sur trois bases de données provenant de l'EFF (2010-2011), de l'ANSSI (2011-2017) et de Rapid7 (2017-2021). Plusieurs vulnérabilités affectant des matériels de fabricants connus furent détectées : modules de petites tailles (strictement inférieures à 1024 bits), modules redondants (utilisés par plusieurs entités), certificats invalides mais toujours en usage, modules vulnérables à l'attaque ROCA ainsi que des modules dits «PGCD-vulnérables» (c'est-à-dire des modules ayant des facteurs communs). Pour la base de données de Rapid7, dénombrant près de 600 millions de certificats (et incluant ceux des matériels récents), nous avons identifié 1,550,382 certificats dont les modules sont PGCD-vulnérables, soit 0.27% du nombre total. Cela a permis de factoriser 14,765 modules de 2048 bits ce qui, à notre connaissance, n'a jamais été fait.En analysant certains modules PGCD-vulnérables, on a pu rétro-concevoir de façon partielle le générateur de modules (de 512 bits) utilisé par certaines familles de pare-feux, ce qui a permis la factorisation instantanée de 42 modules de 512 bits, correspondant aux certificats provenant de 8,817 adresses IPv4.Après avoir constaté que la plupart des modules factorisés avaient été générés par la bibliothèque OpenSSL, on a analysé les codes sources et les méthodes en charge du processus de génération de clefs RSA de plusieurs versions de cette bibliothèque (couvrant la période 2005 à 2021). À travers des expérimentations sur des plateformes à base de processeurs ARM, où l'on s'est mis quasiment dans les mêmes conditions que les matériels vulnérables identifiés, on a réussi à remonter aux causes de la PGCD-vulnérabilité
In this work, we analyze X.509 SSL/TLS certificates (using RSA encryption and from hundreds of millions of connected devices) looking for anomalies and notably extend the work of Hastings, Fried and Heninger (2016). Our study was carried out on three databases from EFF (2010-2011), ANSSI (2011-2017) and Rapid7 (2017-2021). Several vulnerabilities affecting devices from well-known manufacturers were detected: small moduli (strictly less than 1024 bits), redundant moduli (used by several entities), invalid certificates but still in use, moduli vulnerable to the ROCA attack as well as so-called “GCD-vulnerable” moduli (i.e. moduli having common factors). For the Rapid7 database, counting nearly 600 million certificates (and including those for recent devices), we have identified 1,550,382 certificates whose moduli are GCD-vulnerable, that is 0.27% of the total number. This made it possible to factor 14,765 moduli of 2048 bits which, to our knowledge, has never been done.By analyzing certain GCD-vulnerable moduli, we were able to partially reverse-engineer the modulus generator (of 512 bits) used by certain families of firewalls, which allowed the instantaneous factorization of 42 moduli of 512 bits, corresponding certificates from 8,817 IPv4 addresses.After noting that most of the factored moduli had been generated by the OpenSSL library, we analyzed the source codes and the methods in charge of the RSA key generation process of several versions of this library (covering the period 2005 to 2021). Through experiments on platforms based on ARM processors, where we put ourselves in almost the same conditions as the vulnerable devices identified, we managed to trace the causes of the PGCD-vulnerability

?High harmonic generation is a well established technique to investigate the structure and the inner dynamics of atoms and molecules. This thesis describes how the generating field parameters can be manipulated to extend the limits imposed on the technique by the use of traditional laser sources. In this field, with traditional source we mean high intensity, linearly polarised laser pulses at 800 nm. The first parameter to be investigated is the wavelength λ of the generating beam. The unfavourable scaling of the high harmonic yield with λ seems to suggest that high harmonic spectroscopy of atoms and molecules should be restricted to the wavelengths that obviate this problem, and that therefore shorter wavelength should be used. But longer wavelengths, in the mid infrared, present a great advantage respect to shorter ones. The maximum harmonic order that we can obtain is proportional to the ionisation potential of the target and to the wavelength times the intensity of the beam, so a higher number of harmonic can be produced with a longer wavelength than with short, the intensity being equal. This becomes incredibly valuable when the specie under investigation is a molecule with low ionisation potential. To produce high harmonics, a linearly polarised beam is required. If ellipticity is introduced in the beam, the harmonic signal quickly fades out, as non-linearly polarisation in monochromatic beams switches off the mechanism at the basis of high harmonic generation. This is not true if the polarisation of the beam is changed through the introduction of an additional laser beam, perpendicularly polarised respect to the fundamental. In this thesis the additional degree of freedom that this second field implies is investigated by combining the fundamental with its second harmonic and by controlling the relative delay of the two with sub-cycle precision. The key result is that the addition of the second harmonic gives access to the control of the harmonic amplitude and to the time at which the high harmonics are emitted, by simply controlling the relative phase between the two pulses.

Control law design can be an iterative and time-consuming process. The design procedure can often include manual tuning, not uncommonly in the form of trial and error. Modern software tools may alleviate this process but are generally not developed for use within any speciﬁc industry. There is therefore an apparent need to develop ﬁeld-speciﬁc tools to facilitate control law design.The main contribution of this thesis is the investigation of a systematic and simpliﬁed approach to semi-automatic generation of control law parameters for generic ﬁghter aircraft. The investigated method aims to reduce human workload and time spent on complex decision making in the early stages of aircraft development. The method presented is based on gain scheduled LQI-control with piece-wise linear interpolation. A solution to the automated tuning problem of the associated weighting matrices Q and R is investigated. The method is based on an LQ-optimal eigenstructure assignment. However, the derived method suﬀers from problem regarding practical implementation, such as the seemingly narrow LQ-optimal root-loci of the linearized aircraft model.Furthermore, the inherent problem of hidden coupling is discussed in relation to gain scheduled controllers based on conventional series expansion linearization. An alternative linearization method is used in order to circumvent this problem. Moreover, the possible beneﬁts and disadvantages of control allocation is addressed in the context of actuator redundancy. It is concluded that one may achieve a somewhat simpler handling of constraints at the expense of some model accuracy due to the inevitable exclusion of servo dynamics.

The efficient use of energy at all stages along the energy supply chain and the utilization of renewable energies are very important elements of a sustainable energy supply system, specially at the conversion from thermal to electrical energy. Converting the low-grade waste heat into electrical power would be useful and effective for several primary and secondary applications. One of the viable means to convert the low-grade waste heat into electrical energy is the use of thermoelectric power conversion. The performance of thermoelectric generators, subjected to thermal effects, can vary considerably depending on the operating conditions, therefore it is necessary to measure and have a better understanding of the characteristics and performance of the thermoelectric generator. It is important to understand the thermoelectric generator’s dynamic behavior and interaction with its operating environmental parameters. Based on this knowledge, it is then significant to develop an effective mathematical model that can provide the user with the most probable outcome of the output voltage. This will contribute to its reliability and calculation to increase the overall efficiency of the system. This thesis provides the transient solution to the three-dimensional heat transfer equation with internal heat generation. It goes on to describes the transfer and generation of heat across the thermoelectric generator with dynamic exchange of heat. This solution is then included in a model in which the thermal masses and the operating environmental parameters of the thermoelectric generator are factored in. The resulting model is created in MATLAB. The comparison with experimental results from a thermoelectric generator system confirms the accuracy of the artificial neural network model. This thesis also presents two practical applications, the prediction of the input parameters with a given output voltage, and sensitivity analysis designed for the model. This is to enable users to customize the thermoelectric generator for their requirements. This allows for better usage of resources eventually.

The Queensland University of Technology (QUT) allows the presentation of a thesis for the Degree of Doctor of Philosophy in the format of published or submitted papers, where such papers have been published, accepted or submitted during the period of candidature. This thesis is composed of seven published/submitted papers, of which one has been published, three accepted for publication and the other three are under review. This project is financially supported by an Australian Research Council (ARC) Discovery Grant with the aim of proposing strategies for the performance control of Distributed Generation (DG) system with digital estimation of power system signal parameters. Distributed Generation (DG) has been recently introduced as a new concept for the generation of power and the enhancement of conventionally produced electricity. Global warming issue calls for renewable energy resources in electricity production. Distributed generation based on solar energy (photovoltaic and solar thermal), wind, biomass, mini-hydro along with use of fuel cell and micro turbine will gain substantial momentum in the near future. Technically, DG can be a viable solution for the issue of the integration of renewable or non-conventional energy resources. Basically, DG sources can be connected to local power system through power electronic devices, i.e. inverters or ac-ac converters. The interconnection of DG systems to power system as a compensator or a power source with high quality performance is the main aim of this study. Source and load unbalance, load non-linearity, interharmonic distortion, supply voltage distortion, distortion at the point of common coupling in weak source cases, source current power factor, and synchronism of generated currents or voltages are the issues of concern. The interconnection of DG sources shall be carried out by using power electronics switching devices that inject high frequency components rather than the desired current. Also, noise and harmonic distortions can impact the performance of the control strategies. To be able to mitigate the negative effect of high frequency and harmonic as well as noise distortion to achieve satisfactory performance of DG systems, new methods of signal parameter estimation have been proposed in this thesis. These methods are based on processing the digital samples of power system signals. Thus, proposing advanced techniques for the digital estimation of signal parameters and methods for the generation of DG reference currents using the estimates provided is the targeted scope of this thesis. An introduction to this research – including a description of the research problem, the literature review and an account of the research progress linking the research papers – is presented in Chapter 1. One of the main parameters of a power system signal is its frequency. Phasor Measurement (PM) technique is one of the renowned and advanced techniques used for the estimation of power system frequency. Chapter 2 focuses on an in-depth analysis conducted on the PM technique to reveal its strengths and drawbacks. The analysis will be followed by a new technique proposed to enhance the speed of the PM technique while the input signal is free of even-order harmonics. The other techniques proposed in this thesis as the novel ones will be compared with the PM technique comprehensively studied in Chapter 2. An algorithm based on the concept of Kalman filtering is proposed in Chapter 3. The algorithm is intended to estimate signal parameters like amplitude, frequency and phase angle in the online mode. The Kalman filter is modified to operate on the output signal of a Finite Impulse Response (FIR) filter designed by a plain summation. The frequency estimation unit is independent from the Kalman filter and uses the samples refined by the FIR filter. The frequency estimated is given to the Kalman filter to be used in building the transition matrices. The initial settings for the modified Kalman filter are obtained through a trial and error exercise. Another algorithm again based on the concept of Kalman filtering is proposed in Chapter 4 for the estimation of signal parameters. The Kalman filter is also modified to operate on the output signal of the same FIR filter explained above. Nevertheless, the frequency estimation unit, unlike the one proposed in Chapter 3, is not segregated and it interacts with the Kalman filter. The frequency estimated is given to the Kalman filter and other parameters such as the amplitudes and phase angles estimated by the Kalman filter is taken to the frequency estimation unit. Chapter 5 proposes another algorithm based on the concept of Kalman filtering. This time, the state parameters are obtained through matrix arrangements where the noise level is reduced on the sample vector. The purified state vector is used to obtain a new measurement vector for a basic Kalman filter applied. The Kalman filter used has similar structure to a basic Kalman filter except the initial settings are computed through an extensive math-work with regards to the matrix arrangement utilized. Chapter 6 proposes another algorithm based on the concept of Kalman filtering similar to that of Chapter 3. However, this time the initial settings required for the better performance of the modified Kalman filter are calculated instead of being guessed by trial and error exercises. The simulations results for the parameters of signal estimated are enhanced due to the correct settings applied. Moreover, an enhanced Least Error Square (LES) technique is proposed to take on the estimation when a critical transient is detected in the input signal. In fact, some large, sudden changes in the parameters of the signal at these critical transients are not very well tracked by Kalman filtering. However, the proposed LES technique is found to be much faster in tracking these changes. Therefore, an appropriate combination of the LES and modified Kalman filtering is proposed in Chapter 6. Also, this time the ability of the proposed algorithm is verified on the real data obtained from a prototype test object. Chapter 7 proposes the other algorithm based on the concept of Kalman filtering similar to those of Chapter 3 and 6. However, this time an optimal digital filter is designed instead of the simple summation FIR filter. New initial settings for the modified Kalman filter are calculated based on the coefficients of the digital filter applied. Also, the ability of the proposed algorithm is verified on the real data obtained from a prototype test object. Chapter 8 uses the estimation algorithm proposed in Chapter 7 for the interconnection scheme of a DG to power network. Robust estimates of the signal amplitudes and phase angles obtained by the estimation approach are used in the reference generation of the compensation scheme. Several simulation tests provided in this chapter show that the proposed scheme can very well handle the source and load unbalance, load non-linearity, interharmonic distortion, supply voltage distortion, and synchronism of generated currents or voltages. The purposed compensation scheme also prevents distortion in voltage at the point of common coupling in weak source cases, balances the source currents, and makes the supply side power factor a desired value.

In the monograph the literature information about the nature of stochastic processes and their participation in the work of the brain and human behavior. Established that the real cognitive processes and mental functions associated with the procedural side of external events and the stochastic properties of the internal dynamics of brain systems in the form of fluctuations of their parameters, including cardiac rhythm generation and sensorimotor reactions. Experimentally proved that the dynamics of the measured physiological processes is in the range from chaotic regime to a weakly deterministic — fractal mode. Fractal mode determines the maximum order and organization homeostasis of cognitive processes and States, as well as high adaptive ability of the body systems with fractal properties. The fractal-chaotic dynamics is a useful quality to examine the actual physiological and psychological systems - a unique numerical identification of the order and randomness of the processes through calculation of fractal indices. The monograph represents the results of many years of experimental studies of the reflection properties of stochastic sensorimotor reactions, as well as stochastic properties of heart rate in children, Teens and adults in the age aspect in the speech activity and the perception of different kinds of music with its own frequency-spectral structure. Designed for undergraduates, graduate students and researchers that perform research and development on cognitive psychology and neuroscience.

This chapter provides an understanding of the fundamental principles behind key management. We consider the typical stages in the lifecycle of a cryptographic key and then review each of these stages in some detail. We discuss the choosing of key lengths and look at different techniques for key generation, including key derivation and generation from components. We then look at different techniques for key establishment, including the use of key hierarchies, key wrapping, and quantum key establishment. We then look at key storage and discuss the role of hardware security modules. We also consider key separation, key change, and key destruction, before closing with a short discussion on governance of key management.

With the advent of quantum computing, it urges the deﬁnition of a cryptographic standard algorithm that can resist attacks from a quantum computer. Inside this context is GeMSS, a multivariate quadratic signature scheme based on the HFEvconstruct. Schemes of this type have shown great potential throughout the last two decades. This paper traces a comparison of performance and security between GeMSS and other relevant digital signature schemes, showing that despite of its slow signature generation and large key pair, it has a very quick veriﬁcation process and tiny signatures. It also proposes a method for deriving the size of keys from the security parameter evaluated.
