Post-quantum encryption technology based on BRLWE for internet of things by Yitian GAO, Liquan CHEN, Tianyang TU, Yuan GAO, Qianye CHEN

“…With the development of quantum computers, the classical public key encryption system is not capable enough to guarantee the communication security of internet of things (IoT).Because the mathematical puzzles which post-quantum encryption algorithms are based on cannot yet be broken by quantum computers, these new algorithms have good anti-quantum computing security.In particular, the lattice-based cryptography is expected to become the main technology of the next generation public key cryptosystem.However, post-quantum encryption algorithms have the disadvantages of large amount of computation and high storage space.The communication efficiency of IoT will be affected if post-quantum encryption algorithms are directly applied to the lightweight device under IoT environment.In order to better guarantee the communication security and improve the commutation efficiency of IoT, Sym-BRLWE (symmetrical binary RLWE) encryption scheme was proposed.Sym-BRLWE was improved from the existing post-quantum encryption scheme based on BRLWE (binary ringlearning with errors) problem.Specifically, Sym-BRLWE encryption algorithm met the efficiency requirements of IoT via improving the random number selection on the discrete uniform distribution and the calculation of the polynomial multiplication.Sym-BRLWE encryption algorithm achieved high efficiency and high security via adding encryption security precautions, then it is more suitable for IoT lightweight devices.From the security analysis, the proposed Sym-BRLWE encryption scheme had high security.It could theoretically resist lattice attacks, timing attacks, simple power analysis (SPA) and differential power analysis (DPA).From simulation experiments, which were carried out in a binary computing environment simulating an 8-bit micro-device, the proposed Sym-BRLWE encryption scheme has high efficiency and small key size in encryption and decryption.It could reduce the total encryption time by 30% to 40% when compared with other BRLWE-based encryption schemes with the parameter selection of the 140 bit quantum security level.…”

Spatiotemporal Variation Characteristics of Dry/Wet Spells in Longitudinal Range-Gorge Region of the Tropic of Cancer by JIN Hanyu, CHENG Qingping, REN Yitong

“…Under the background of global warming,extreme climate events occur frequently.Understanding the change in precipitation from multiple perspectives is of great significance to the utilization of water resources.Specifically,the daily precipitation data at 24 stations along the Tropic of Cancer in the Longitudinal Range-Gorge Region (LRGR) from 1961 to 2019 are used to calculate 14 wet/dry spell indices.Methods including the revised Mann-Kendall test,Pettitt,and wavelet coherence are adopted to reveal the spatiotemporal variation characteristics of the dry/wet spell indices and their correlation with the large-scale circulation index.The results indicate that:① the wet and dry spells in LRGR of the Tropic of Cancer show a significant decreasing and increasing trend,respectively,especially in the area west of Yuanjiang River and south of the Tropic of Cancer.The change in the wet and dry spell indices of most stations is mainly concentrated in 2002.② The frequency of short-duration wet spells and the contribution rate to annual precipitation demonstrate an increasing trend,and those of the medium-long-duration wet spells demonstrate a decreasing trend;the short-duration dry spells are in decline while medium-long-duration dry spells are rising,and the entire region tends to aridification.③ The extreme dry spell index is closely related to ENSO,and it has a negatively correlated co-occurrence cycle of about six years;the extreme wet spell index is closely related to the summer monsoon of the South China Sea,and it has a positively correlated co-occurrence cycle of about eight years.To sum up,the above analysis shows that dry and wet spell indices in LRGR of the Tropic of Cancer demonstrate an overall trend of aridification,which means that the drought risks are increasing.Their spatiotemporal variation characteristics and local differences may be closely related to the joint influence of the large-scale circulation index,monsoon,and channel-blocking in LRGR.…”
