Summary: The use of chaotic systems such as PRNGs in electronics is appealing, but continuous-time systems are used less due to their strong temporal correlations requiring additional computations. A methodology for achieving chaos-based PRNGs with good statistical characteristics and high throughput is proposed, and these PRNGs successfully pass tests and require few hardware resources.

Summary: This work proposes a method to generate 1-D pseudo-chaotic sequences based on the discrete Arnold's map defined over the integer ring Z(2)m. The period of the generated sequences is investigated using properties of the Fibonacci sequence over Z(2)m. The statistical properties of the PRNG are analyzed, and it is shown that the proposed PRNG has higher throughput and competitive hardware consumption compared to other architectures in the literature.

Summary: In this work, a new 2D discrete hyper-chaotic map with linear cross-coupled topological structure combined with the Tent and Logistic map is constructed, outperforming other enhanced chaotic maps developed recently. An efficient PRNG based on the proposed map is then implemented on FPGA, generating sequences with high randomness and passing various tests successfully. Experimental results show that the proposed PRNG occupies only 1.4% of the available FPGA resources, while achieving a clock frequency of 158 MHz with a maximum throughput of 9.26 Gbps, outperforming the state-of-the-art.

Summary: The objective of this study was to implement a parameter-switching chaos control scheme for fractional-order spherical systems and develop a chaos-based image encryption and transmission system. The novelty of the communication system lies in its application of the parameter-switching scheme in the decryption process of RGB and grayscale images. The system has been demonstrated numerically and implemented on two FPGAs, and the results show effective chaos control and encryption without loss of quality.

Summary: This paper presents an unsigned integer encoded PRNG based on the delayed quantized Arnold's Cat Map (QACM) that exhibits true periodic orbits with large periods. The proposed PRNG is obtained by delaying one of the 2-D QACM outputs with a linear feedback shift register (LFSR) thereby increasing its period. The period of the PRNG increases with an increase in the delay and bit-precision.

Summary: This paper investigates the potential of Cellular Automata (CAs) represented by first degree equations as a source of randomness. A greedy filtering technique is developed to identify candidate CAs using existing chaotic parameters. Through theoretical strategy and experimental verification, a list of good first degree CA parameters is identified that remain excellent sources of randomness regardless of changes in the number of states. Finally, the CAs are utilized as pseudo-random number generators.

Summary: This paper proposes an effective lightweight LZUC cipher based on chaotic system to improve the traditional ZUC algorithm, which achieves certain lightweighting effects and has good statistical properties and security of the output sequence. The performance of the LZUC cipher is verified through NIST statistical tests and analysis of typical attacks. In addition, an image security system is designed using the LZUC cipher to further validate the encryption effectiveness through analysis of plaintext and ciphertext data.

Summary: The proposed scheme in this paper effectively addresses the issue of dynamical degradation in chaotic systems due to finite arithmetic precision by saving portions of the chaotic sequence history, comparing it with saved samples, and perturbing the chaotic orbit to prevent cycling. It provides better results than the original map in terms of statistical properties and unpredictability, without the need for higher arithmetic precision that is costly to implement.

Summary: This paper proposes a novel N-PTS scheme to address the issues of high PAPR and overlapping structure in the Filter Bank Multicarrier system, while reducing computational complexity. The scheme utilizes FBMC-OQAM signals and calculates the lowest PAPR value from data in a Storage Device, using side information to recover the signal at the receiver end effectively. There is no need for extra bits to be transmitted, and the performance in terms of BER remains satisfactory.
