Streszczenie:

In this paper we present an optimized software implementation (sFFT-4.0)of the recently developed Nearly Optimal Sparse Fast Fourier Transform (sFFT) algorithm for the noisy case. First, we developed a modified versionof the Nearly Optimal sFFT algorithm for the noisy case, this modified algorithm solves the accuracy issues of the original version by modifying theflat window and the procedures; and second, we implemented the modifiedalgorithm on a multicore platform composed of eight cores. The experi-mental results on the cluster indicate that the developed implementation isfaster than direct calculation using FFTW library under certain conditions of sparseness and signal size, and it improves the execution times of previous implementations like sFFT-2.0. To the best knowledge ofthe authors,the developed implementation is the first one of the Nearly Optimal sFFT algorithm for the noisy case.

Streszczenie:

The SPEEDY block cipher family announced at the CHES 2021 shows excellent performance on hardware architectures. Due to the nature of the hardware-friendly design of SPEEDY, the algorithm has low performance for software implementations. In particular, 6-bit S-box and bit permutation operations of SPEEDY are inefficient in software implementations, where it performs word-wise computations. We implemented the SPEEDY block cipher on a 32-bit microcontroller for the first time by applying the bit-slicing techniques. The optimized encryption performance results on ARM Cortex-M3 for SPEEDY-5-192, SPEEDY-6-192, and SPEEDY-7-192 are 65.7, 75.25, and 85.16 clock cycles per byte (i.e., cpb), respectively. It showed better performance than AES-128 constant-time implementation and GIFT constant-time implementation in the same platform. In RISC-V, the performance showed 81.9, 95.5, and 109.2 clock cycles per byte, which outperformed the previous works. Finally, we conclude that SPEEDY can show efficient software implementation on low-end embedded environments.

Streszczenie:

<p>MQTT (Message Queue Telemetry Transport) is one of the most popular Internet of Things (IoT) communication protocols, owing to its lightweight and easiness to use. The previous MQTT standards (including version 3.1 and its precedents) do not provide proper security functions; instead, they assume the adoption of SSL/TLS in the underlying layer. However, it not only incurs larger overhead but also hinders the development of suitable authentication/confidentiality protection to suit various MQTT deployment scenarios. The newest MQTT standard called MQTT 5.0 responds to these challenges by supporting the Enhanced Authentication framework in which designers can design and implement any secure authentication mechanisms within the framework. This paper designs and implements two efficient authentication protocols, using the MQTT 5.0 Enhanced Authentication framework. One is simple challenge-response authentication scheme, and the other is an anonymous challenge-response authentication scheme. We extend HiveMQ platform to implement the schemes and evaluate the performance. The results show that the proposed schemes demand only hundred few more milliseconds to achieve much robust authentication, compared to the simple identity-password authentication.</p> <p> </p>

The processing of complicated surface is always a tough job in multi-axis machining. Pilger-roller is a kind of tool molds with complicated surface. To process the complicated grooved-surface of Pilger-roller, an algorithm, which included grooved-surface modeling, tool-path planning and cutter location (CL) computation, is proposed and implemented. The tool-path generated by this algorithm is smooth and has no interference. In order to meet the demand of Pilger-roller processing in efficiency and automation, automatically-processing software is developed based on Original Equipment Manufacturer (OEM). Compared with the conventional methods, this software makes the online programming visualized and efficient. This software has been applied to actual production and could meet the commercial requirement.

The software development process has many variations. Each software development technique has its own advantages and disadvantages. There are efficient development processes and some could be more efficient. This research aims to build a web-based application efficiently utilizing component-based and ORM with a case study of financial management applications on community radio. This research begins with data collection through observations and interviews, requirement analysis, and system design, implementation, and testing. This research shows that combining component-based software development and object-relational mapping (ORM) can increase software development efficiency compared to non-component-based and pure SQL.

AbstractWe describe how the Hardy–Ramanujan–Rademacher formula can be implemented to allow the partition function p(n) to be computed with softly optimal complexity O(n1/2+o(1)) and very little overhead. A new implementation based on these techniques achieves speedups in excess of a factor 500 over previously published software and has been used by the author to calculate p(1019), an exponent twice as large as in previously reported computations. We also investigate performance for multi-evaluation of p(n), where our implementation of the Hardy–Ramanujan–Rademacher formula becomes superior to power series methods on far denser sets of indices than previous implementations. As an application, we determine over 22 billion new congruences for the partition function, extending Weaver’s tabulation of 76 065 congruences. Supplementary materials are available with this article.

In this paper an area-efficient hardware implementation of a Bincombgen algorithm was presented. This algorithm generates all (n,k) combinations in the form of binary vectors. The generator was implemented using Verilog language and synthesized using Xilinx and Intel-Altera software. Some changes were applied to the original code, which allows our FPGA implementation to be more efficient than in the previously published papers. The usage of chip resources and maximum clock frequency for different values of n and k parameters are presented.

Streszczenie:

This paper presents an implementation of Rivest, Shamir and Adleman (RSA) cryptosystem based on hardware/software (HW/SW) co-design. The main operation of RSA is the modular exponentiation (ME) which is performed by repeated modular multiplications (MMs). In this work, the right-to-left (R2L) algorithm is used for the implementation of the ME as a programmable system on chip (PSoC). The processor MicroBlaze of Xilinx is used for flexibility. The R2L method is often suggested to improve the timing performance, since it is based on parallel computations of MMs. However, if the optimization of HW resources is a constraint, this method can be executed sequentially using a single modular multiplier as a custom intellectual property (IP). Consequently, the execution time of the ME becomes dependent of three factors, namely the capability of the custom IP to perform the MMs, the nonzero bit string of the exponent and the communication link between the processor and the custom IP. In order to achieve the best trade-off between area, speed and flexibility, we propose three implementations in this work. The first one is a pure software solution. The second one takes benefit of a HW accelerator dedicated to the MM execution. The last one is based on a dual strategy. Two parallel MMs are implemented within a custom IP and local memories are used close to the arithmetic units to minimize the communication link influence. The results show that in the application to RSA 1024-bits, the ME runs in 22,25 ms, while using only 1,848 slices.

Streszczenie:

Side-channel attacks, which are capable of breaking secrecy via side-channel information, pose a growing threat to the implementation of cryptographic algorithms. Masking is an effective countermeasure against side-channel attacks by removing the statistical dependence between secrecy and power consumption via randomization. However, designing efficient and effective masked implementations turns out to be an error-prone task. Current techniques for verifying whether masked programs are secure are limited in their applicability and accuracy, especially when they are applied. To bridge this gap, in this article, we first propose a sound type system, equipped with an efficient type inference algorithm, for verifying masked arithmetic programs against higher-order attacks. We then give novel model-counting-based and pattern-matching-based methods that are able to precisely determine whether the potential leaky observable sets detected by the type system are genuine or simply spurious. We evaluate our approach on various implementations of arithmetic cryptographic programs. The experiments confirm that our approach outperforms the state-of-the-art baselines in terms of applicability, accuracy, and efficiency.

Streszczenie:

This paper, according to the best of our knowledge, provides the very first solution to the hardware implementation of the complete decision tree inference algorithm. Evolving decision trees in hardware is motivated by a significant improvement in the evolution time compared to the time needed for software evolution and efficient use of decision trees in various embedded applications (robotic navigation systems, image processing systems, etc.), where run-time adaptive learning is of particular interest. Several architectures for the hardware evolution of single oblique or nonlinear decision trees and ensembles comprised from oblique or nonlinear decision trees are presented. Proposed architectures are suitable for the implementation using both Field Programmable Gate Arrays (FPGA) and Application Specific Integrated Circuits (ASIC). Results of experiments obtained using 29 datasets from the standard UCI Machine Learning Repository database suggest that the FPGA implementations offer significant improvement in inference time when compared with the traditional software implementations. In the case of single decision tree evolution, FPGA implementation of H_DTS2 architecture has on average 26 times shorter inference time when compared to the software implementation, whereas FPGA implementation of H_DTE2 architecture has on average 693 times shorter inference time than the software implementation.

AbstractWe propose a simple, computationally efficient scheme for an X-ray spectrum simulator. The theoretical models describing the physical processes involved are employed in our Monte Carlo software in a coherent way, paving the way for straightforward future improvements. Our results compare satisfactorily to experimental results from literature and to results from dedicated simulation software. The simplicity, excellent statistical errors, and short execution time of our code recommend it for intensive use in X-ray generation simulations.

Streszczenie:

Information and communication technologies have changed the way in which citizens interact with Public Administrations. Digital literacy is key for the development of the Liquid Society, and Public Administrations must take the lead in promoting more efficient, universal, and user oriented public services. The migration to open source standards allows Public Administration to offer more democratic, universal, and efficient channels for establishing relationships with citizens. In this article, the authors present international experiences that show how certain Public Administrations have migrated to open source software to promote digital literacy in the contexts they are operating. The final results depend on contextual and organizational factors, including the need to change, the political support and the existence of available technological resources, the organizational climate, motivation levels of human resources, and the kind of leadership for the project or the organizational complexity. Change efforts have strategic and organizational impacts that the organization must evaluate beforehand.

In recent years, several hardware accelerators for CAVLC have been designed. In contrast, high-performance software implementations of CAVLC (e.g., GPU-based) are scarce. A high-performance GPU-based implementation of CAVLC is desirable in several scenarios. On the one hand, it can be exploited as the entropy component in GPU-based H.264 encoders, which are a very suitable solution when GPU built-in H.264 hardware encoders lack certain necessary functionality, such as data encryption and information hiding. On the other hand, a GPU-based implementation of CAVLC can be reused in a wide variety of GPU-based compression systems for encoding images and videos in formats other than H.264, such as medical images. This is not possible with hardware implementations of CAVLC, as they are non-separable components of hardware H.264 encoders. In this paper, we present CAVLCU, an efficient implementation of CAVLC on GPU, which is based on four key ideas. First, we use only one kernel to avoid the long latency global memory accesses required to transmit intermediate results among different kernels, and the costly launches and terminations of additional kernels. Second, we apply an efficient synchronization mechanism for thread-blocks (In this paper, to prevent confusion, a block of pixels of a frame will be referred to as simply block and a GPU thread block as thread-block.) that process adjacent frame regions (in horizontal and vertical dimensions) to share results in global memory space. Third, we exploit fully the available global memory bandwidth by using vectorized loads to move directly the quantized transform coefficients to registers. Fourth, we use register tiling to implement the zigzag sorting, thus obtaining high instruction-level parallelism. An exhaustive experimental evaluation showed that our approach is between 2.5$$\times$$ × and 5.4$$\times$$ × faster than the only state-of-the-art GPU-based implementation of CAVLC.

The paper deals with problems in the post-implementation phase of management Enterprise Resource Planning (ERP) systems. Proper management of the system maintenance stage is a basis for efficient system development in terms of business needs. Based on the research and analysis of collected materials, it turns out that making a decision to upgrade the system is equally crucial. We present revealed mechanisms determining the post-implementation approach to upgrade or reimplement the ERP system. The main aim is to determine the methodology and difference understanding to achieve success in the post-implementation stage. The paper shows that the systemic approach to the maintenance stage of the ERP system affects its further decisions: upgrade or reimplement. It has a direct impact on future maintenance costs and the scope of new business demands. This research is an outcome of industry–academia collaboration and based on several developed implementation systems, achieved upgrade and reimplementation projects. Based on case study analysis, we show that reimplementation means an evolution of the current ERP processes rather than another attempt to “reimplement” an unsuccessful system implementation. On the other hand, upgrades are not only a tool or system actualization but the easiest way to bolster company sustainability and to have the information system up to date. The issues discussed in the article will be used to develop changes in the implementation methodology of ERP systems.

The graphics processing unit (GPU) has now become an integral part of our lives through both desktop and portable devices. Thanks to dedicated hardware, visualization has been significantly accelerated, softwares today only use the GPU for rasterization. As a result of this development, now we use only triangle-based rendering, and pixel-based image manipulations can only be performed using shaders. It can be stated that today’s GPU pipeline cannot provide the same flexibility as the previous software implementation. This paper discusses an efficient software implementation of pixel-based rasterization. After reviewing the current GPU-based drawing process, we will show how to access pixel level drawing in this environment. Finally, a more efficient storage and display format than the classic solution is presented, which performance far exceeds the previous solution.
