Texto completoThis Ph. D, devoted to symmetric cryptography, addresses two separate aspects of cryptology. First, the protection of messages using encryption algorithms and, second, the protection of privacy through authentication protocols. The first part concerns the study of linear cryptanalysis while the second is devoted to the design of authentication protocols with proven security. Although introduced in the early 90s, linear cryptanalysis has recently experienced a revival due to the development of new variants. We are both interested in its practical and theoretical aspects. First, we present a cryptanalysis of a reduced version of SMS4, the encryption algorithm used in WiFi in China then, second, we introduce multilinear cryptanalysis and describe a new form of multilinear cryptanalysis. The second part of the thesis concerns the study of RFID authentication protocols respecting privacy. We define a model to formalize the notions of security for these protocols. Then we propose two protocols, each one performing a compromise between strong unlinkability and resistance to denial of service attacks, which allow low-cost implementations. We establish security proofs in the standard model for these two protocols

Texto completoRFID tags are small electronic devices that will be put on almost every item sold. Since RFIDs are so small, they can only use extremely lightweight security protocols, offering a unique challenge to researchers. Security protocols for RFIDs have been in the forefront of academic research in the past years. This thesis outlines what RFIDs are, and describes and analyses multiple RFID security solutions. We present the state of the art in the field of RFIDs, next, we iIIustrate and analyse the Di Pietro-Molva private RFID authentication protocol, detailing its shortcomings and insecurities. Then, we describe the privacy-preserving RFID identification protocol ProblP and analyse its security. An improved version of ProblP. EProbIP, is also presented, which counters the insecurities found in original protocol. Finally, we describe how low hardware-complexity stream ciphers could be used in RFIDs and analyse such ciphers using a SAT sol ver which we improved for this purpose

Texto completoWhile RFID systems are one of the key enablers helping the prototype of pervasive computer applications, the deployment of RFID technologies also comes with new privacy and security concerns ranging from people tracking and industrial espionage to produ ct cloning and denial of service. Cryptographic solutions to tackle these issues were in general challenged by the limited resources of RFID tags, and by the formalizations of RFID privacy that are believed to be too strong for such constrained devices. It follows that most of the existing RFID-based cryptographic schemes failed at ensuring tag privacy without sacrificing RFID scalability or RFID cost effectiveness. In this thesis, we therefore relax the existing definitions of tag privacy to bridge the gap between RFID privacy in theory and RFID privacy in practice, by assuming that an adversary cannot continuously monitor tags. Under this assumption, we are able to design sec ure and privacy preserving multi-party protocols for RFID-enabled supply chains. Namely, we propose a protocol for tag ownership transfer that features constant-time authentication while tags are only required to compute hash functions. Then, we tackle the problem of product genuineness verification by introducing two protocols for product tracking in the supply chain that rely on storage only tags. Finally, we present a solution for item matching that uses storage only tags and aims at the automation of safety inspections in the supply chain.The protocols presented in this manuscript rely on operations performed in subgroups of elliptic curves that allow for the construction of short encryptions and signatures, resulting in minimal storage requirements for RFID tags. Moreover, the privacy and the security of these protocols are proven under well defined formal models that take into account the computational limitations of RFID technology and the stringent privacy and security requirements of each targeted supply chain application

Texto completoOver the 30 last years, active RFID devices have evolved from nodes dedicated to identification to autonomous nodes that, in addition, sense (from environment or other sources) and exchange data. Consequently, the range of their applications has rapidly grown from identification only to monitoring and real time localisation. In recent years, thanks to their advantages, the use of active RFID nodes for mobile data collection has attracted significant attention. However, in most scenarios, these nodes are unattended in an adverse environments, so data must be securely stored and transmitted to prevent attack by active adversaries: even if the nodes are captured, data confidentiality must be ensured. Furthermore, due to the scarce resources available to nodes in terms of energy, storage and/or computation, the used security solution has to be lightweight. This thesis is divided in two parts. In the first, we will study in details the evolution of active RFID nodes and their security. We will then, present, in the second part, a new serverless protocol to enable MDCs (Mobile Data Collectors), such as drones, to collect data from mobile and static Active RFID nodes and then deliver them later to an authorized third party. The whole solution ensures data confidentiality at each step (from the sensing phase, before data collection by the MDC, once data have been collected by MDC, and during final delivery) while fulfilling the lightweight requirements for the resource-limited entities involved. To assess the suitability of the protocol against the performance requirements, we will implement it on the most resource-constrained secure devices to prove its efficiency even in the worst conditions. In addition, to prove the protocol fulfills the security requirements, we will analyze it using security games and we will also formally verify it using the AVISPA and ProVerif tools

Texto completoThe rapid advancements in wireless technologies to meet the escalating demand for wireless data traffic, have also raised the public's risk perception due to the increased emission of electromagnetic fields (EMFs). In response to these concerns, international guidelines have been established to avoid overexposure that can potentially induce adverse health effects.Given that people spend more than 70% of their daily time in indoor environments, efforts to assess indoor RF-EMF exposure have intensified. However, assessment of indoor exposure to RF-EMF using a deterministic approach is a challenging and time consuming task as it is affected by uncertainties due to the complex interaction of EMFs with different obstructions whose geometry and dielectric properties are unknown in a dynamic indoor environment. In addition, the available base station information is limited.In this study, we characterize the spatial and temporal indoor RF-EMF exposure in three-level buildings by developing statistical and AI-based models. The buildings are located in more than 200 meters vicinity of outdoor cellular antennas supporting several cellular technologies (2G, 3G, 4G, and 5G). Different measurement campaigns have been conducted to develop the statistical and AI-based models. In addition, RF sensors, that monitors the temporal variation of the total indoor RF-EMF exposure, has been installed in the rear offices on each floor of the buildings to provide a representative measurement.We identify the key parameters that characterize the indoor RF-EMF exposure by performing a one-sample Kolmogorov-Smirnov (K-S) test on exposure measurement data. The result of this statistical test indicates that the indoor RF-EMF exposure on each floor, along the length of a wing, can be modeled using a Gaussian (normal) distribution. The result implies that the exposure levels can be fully characterized by the mean and standard deviation parameters.The evaluation of autocorrelation of long-term sensor measurement data indicates that the time series data exhibit a clear daily periodicity, which is consistent over various weeks, months, seasons, and years. We develop robust polynomial regression and AI-based models using long-term time series sensor measurement data to capture the 24-hour time variability of total indoor RF-EMF exposure. The models provide a good high-level representation of hourly fluctuations in the mean exposure levels of the 24-hour temporal variation.We develop novel multivariate polynomial and linear regression models to predict the mean and standard deviation of the total RF-EMF exposure level, respectively. To more effectively capture the impact of antenna beam gain, we present an innovative approach that segments the main antenna beam into smaller subbeams. This innovative technique allows the models to capture more accurately the differences in beam gain experienced by each wing of the building. The beam factor has been specifically designed to summarize the key information about the base station antennas. This parameter enables the models to adapt whenever there are changes in the infrastructure of the cellular base stations. The measurements of the reference sensors provide real-time input to the models. The statistical models serve as a powerful RF mapping tool by estimating both the mean and standard deviation of the total RF-EMF exposure levels on all floors of the buildings

Texto completoThe recent advancement in MRI systems and the increase of the static magnetic field strength were accompanied by a strong concern about the effect of RF electromagnetic fields on patients. The effect can be increased by the use of conductive elements inside the volume coil as in the case of endoluminal coils used to analyze digestive walls. These coils lead to an increase of the local SAR which is induced by RF electric field in the presence of the coaxial cable connecting the coil to the MR system, resulting in strong local heating. Giving that these coils have the potential to present a real benefit to the patient, it worth to overcome these limitations. Accordingly, the first objective of the thesis is the development of a fully optical endoluminal receiver coil. An optical active detuning system has been developed and characterized. The NMR images show a signal-to-noise ratio distribution similar to that obtained with conventional detuning techniques, thus validating the efficiency of the optical detuning. Concerning the electro-optical conversion and the optical transmission of the NMR signal, experiments were performed to overcome constraints related to the use of waveguide for electro-optical conversion by Pockels effect. Moreover, the importance of monitoring global and local SAR during MRI exams remains a need which is not limited only to the endoluminal coils. The second objective of the thesis is then the experimental validation of an electro-optical probe for real-time measurements of RF electric field. This probe can measure the RF electric field in air and in biological media at 3 T and 4.7 T MRI systems and allows the estimation of the local SAR

Texto completoPower amplifiers (PAs) are key elements of telecommunications and radar front ends at radio frequencies. The potential of the PA is limited by the phenomena of dispersion. In this context, we are interested in the characterization of thermal phenomena in the HBT transistors of different technology (GaAs, InP and SiGe) and characterization of thermal and traps effects in HEMT transistors based on GaN (AlGaN and AlInN) at low frequencies. A bench for low frequency S-parameters measurement [10 Hz, 40 GHz] is set up to enable us to study the behavior of the new components in the frequency range seat of nonlinear parasitic phenomena. A simple, yet accurate, method to experimentally characterize the thermal impedance of Hetero junction Bipolar Transistors (HBT) with different technologies proposed. This method relies on low frequency S-parameters measurements. A detailed study has been initiated to characterize the phenomena of low frequency dispersion in the HEMT transistors based on GaN. The thermal and traps effects are studied for both technologies (AlGaN/GaN and AlInN/GaN) with the method of admittance spectroscopy to quantify the levels of deep traps
