Public key cryptographic algorithm SM2 optimized implementation on low power embedded platform by Ganqin LIU, Hui LI, Hui ZHU, Yukun HUANG, Xingdong LIU

“…With the development of wireless communication technology and the popularization of intelligent terminals, more and more cryptographic algorithms are applied to IoT devices to ensure the security of communication and data.Among them, the SM2 elliptic curve public key cryptography proposed by the State Cryptography Administration is an elliptic curve public key cryptography algorithm developed domestically, which has the advantages of high security and short key.SM2 has been widely deployed in various communication systems and is used in essential parts such as identity authentication and key negotiation.However, since SM2 involves large integer operations on finite fields, the computational cost is high, and its execution on a low-power embedded platform seriously affects the user experience.Therefore, an efficient implementation scheme of SM2 algorithm for low-power embedded platform was proposed for ARM-m series processors.Specifically, Thumb-2 instruction set was adopted to handle carry and save addressing cycles, basic operations such as modulo addition and sub-traction of large integers were optimized, and the number of available registers on the platform was combined to build efficient basic operations.Besides, based on the short multiplication and accumulation instruction cycle of ARM-m series processors, the implementation of Montgomery multiplication was optimized, and an efficient modular multiplication scheme was designed in combination with the CIOS algorithm.The scheme was no longer limited to Mersenne primes, and greatly improved the speed and flexibility of modular multiplication.Based on the theoretical analysis and experimental test, the window length selection method of the multiple point-scalar multiplication wNAF sliding window method on the embedded platform was given.The experimental test results show that the proposed scheme can effectively improve the computational efficiency of the SM2 algorithm on the resource-constrained low-power embedded platform.Without pre-calculation, the test signature speed can reach 0.204s/time, the signature verification speed is 0.388s/time, the encryption speed is 0.415s/time, and the decryption speed is 0.197s/time.…”

Genome biology of long non-coding RNAs in humans: A virtual karyotype by Alessandro Palma, Giulia Buonaiuto, Monica Ballarino, Pietro Laneve

“…We found that lncRNAs are unevenly distributed across chromosomes and identified regions of high lncRNA density on chromosomes 18, 13, and X, which overlap with PCG-rich regions. Additionally, we observed that lncRNAs generally exhibit shorter gene lengths and fewer splicing variants compared to protein-coding transcripts, with a subset displaying pronounced clustering patterns that may indicate functional relevance. …”

Features of Measuring the Hardness of a Metal Surface Modified with Ultrafine Particles of Minerals by A. V. Skazochkin, G. G. Bondarenko, P. Żukowski

“…By the method of instrumental hardness, standard measurements were performed without preliminary selection of the indentation site (at a load of 1.05 N) and measurements during indentation into even sections (at low loads of 10 mN).It is noted that the high precision of measurements implemented by instrumental indentation, due to the large roughness of the samples, leads to large values of the error in calculating the measurement results. An additional difference in the results of measurements performed by two methods at shallow indentation depths may be due to the fact that the object under study has a complex structure consisting of a metal matrix and particles distributed over the depth of the sample. …”
