Since NSA announced the plans for transitioning to the algorithms which are resistant to attacks by the potential quantum computers, the interest of implementation of post-quantum cryptography (PQC) on various devices has emerged. Including widely used Java Card, memory-constrained smart cards need the efficient implementation of encryption schemes to resist quantum-computing attacks. Meanwhile, lattice-based...
In this paper, we will describe a statistical study of data analyzed by SPSS software. The aim of our study is to show the importance of sharing emotional states between learners during online communication, which helps to create an adequate environment and a positive cognitive exchange between the teammates. Our study is based on three stages. The first, discussed the satisfaction of learners with...
In this paper, we consider the problem of enhancing the filtering capacity of single standard beamformers for real base-band signals. Unfortunately, the standard smart arrays are not able to effectively minimize the effects of the complex noise in the array. In order to solve this problem, we analyze a parallel adaptive beamforming system based on complex nonlinear adaptive filters. In this design,...
A method for Peak-to-Average Power Ratio (PAPR) reduction in an OFDM system is presented using clipping based on the statistics of a large number of OFDM symbols. The clipping technique uses scaled values of standard deviations of real and imaginary parts of complex discrete samples of OFDM symbols. The trade-off between PAPR and BER for this clipping technique is examined, using extensive numerical...
Memristor characteristics like high speed, low power, and passive memory retention make it suitable for application in several fields. Neuromorphic systems, digital and analog circuits, or simply a memory unit, are some of these applications. A memristor exhibits different properties, which allow each field of application to take the desired advantages of this device. Memristor-based “Implication”,...
A novel high performance pipelined implementation architecture for user-defined floating-point complex division is presented. The major part of the proposed algorithm is derived from conventional Goldschmidt division algorithm. This paper first describes related user-defined floating-point arithmetic based on FPGA. Then the core of the complex division: (A+jC)/B is implemented based on the proposed...
This paper focuses on the low rank plus sparse matrix decomposition problem in big data settings. Conventional algorithms solve high-dimensional optimization problems that scale with the data dimension, which limits their scalability. In addition, existing randomized approaches mostly rely on blind random sampling. In this paper, the drawbacks of random sampling from coherent/structured data matrices...
Suppose that we are able to obtain binary paired comparisons of the form “x is closer to p than to q” for various choices of vectors p and q. Such observations arise in a variety of contexts, including nonmetric multidimensional scaling, unfolding, and ranking problems, often because they provide a powerful and flexible model of preference. In this paper we give a theoretical bound for how well we...
Pinpointing where healthy brain aging leaves off and dementia begins is difficult. Is a slip in memory an expected outcome for a too-busy person or a warning of something else? If an empty-nester loses the motivation to cook, is it a sign that the person is enjoying retirement after a lifetime spent cooking or an early sign of a cognitive decline?
This paper presents an efficient algebraic fault analysis on all four modes of SHA-3 under relaxed fault models. This is the first work to apply algebraic techniques on fault analysis of SHA-3. Results show that algebraic fault analysis on SHA-3 is very efficient and effective due to the clear algebraic properties of Keccak operations. Comparing with previous work on differential fault analysis of...
ACM and the IEEE Computer Society have released their computer engineering curriculum guidelines in December of 2016. The curricular report, tagged CE2016, reflects current computer engineering education and practice that would be relevant for the coming decade. The report provides some examples on ways to map knowledge units to courses and it addresses expected requirements in science and mathematics...
According to the characteristics of aerospace computer products, this paper proposes aerospace computer productization work architecture and its detail implementations, which includes three key factors: product system plan, technical factors and management factors. By adopting this architecture, we can effectively improve the performance of aerospace computer productization.
A card-based protocol enables parties to securely compute a desired function by using physical cards instead of computer devices. Most of the previous works have aimed to achieve protocols with a smaller number of cards for elementary functions (e.g., AND/XOR/COPY). Mizuki and Shizuya's protocols achieve the smallest numbers of cards among the existing protocols. Their XOR and COPY protocols can be...
In the context of higher education, a competence may be understood as the combination of skills, knowledge, attitudes, values, and abilities that underpin effective and/or superior performance in a professional area. The aim of the work reported here was to design a set of procedures to assess a transferable competence, i.e., problem solving, that is basic for learning, in both academic and professional...
Oata Grid provides transparent access to grid user. The grid data stored across distributed storage resources whilst fulfilling the Confidentiality, Integrity, Availability (C,I,A). The stored data is replicated in data grid to increase the availability. Replica Manager uses replica replacement algorithm to decide which replica to be replaced for the new replica when there is not enough space for...
Summary form only given, as follows. The complete presentation was not made available for publication as part of the conference proceedings. Memory can be found in all aspects of the semiconductor world. This tutorial will review the volatile memories found in today’s computers and networking equipment, including DRAM, SRAM and TCAM. For each of these memories we will cover bit cell structure, array...
Galois field (GF) arithmetic is used to implement critical arithmetic components in communication and security-related hardware, and verification of such components is of prime importance. Current techniques for formally verifying such components are based on computer algebra methods that proved successful in verification of integer arithmetic circuits. However, these methods are sequential in nature...
Air Data Computer (ADC) is an electronics device computes air data flight parameters. The objective of this paper is to analyze, simulate, and propose hardware implementation module for the Air Data Computer. Simulation of ADC model has been faced by two problems. The first one was to choose true values of dynamic temperature because it depends on flight altitude and airspeed. The second problem is...
This article analyzes the characteristics of APCO P25 traffic. There are observed problems associated with large volume of audio information, which takes a lot of time and computing and memory resources to process. There is also revealed and substantiated necessity of converting radio broadcast to a verbatim report and its further analysis. There was also assessed existing software and hardware, and...
