    Design of hybrid precoding with successive interference cancellation and alternating direction method of multipliers by Xiongwen ZHAO, Yao LIU, Yu ZHANG, Suiyan GENG, Peng QIN, Zhenyu ZHOU

    Published 2021-05-01
    “…To solve the problem of large power consumption caused by a large number of phase shifter (PS) in millimeter wave multi-antenna systems, a new type of dynamic connection structure was designed.With the goal of maximizing spectrum efficiency, two hybrid precoding schemes, successive interference cancellation (SIC) and successive interference cancellation-alternating direction multiplier (SIC-ADMM), were proposed.In SIC scheme, the sum-rate problem was decomposed into multiple sub-rate problems of different radio frequency links, the analog part was solved by iteration, and the digital part was solved by a low-dimensional equivalent matrix.Based on SIC scheme, an improved SIC-ADMM scheme was further proposed by studying the multi-variable sub-rate problem to achieve rapid convergence and reduce computational complexity effectively.The simulation results show that the proposed schemes have good spectrum and energy efficiencies by comparison with the existing schemes, and are more suitable for large-scale antenna systems.In addition, when a certain percentage of PS is turned off, the proposed scheme can greatly improve energy efficiency by sacrificing a small amount of spectrum efficiency.…”

    Differential fault attack on LiCi cipher by Weijian CHEN, Haoxiang LUO

    Published 2021-04-01
    “…LiCi lightweight block cipher is a new algorithm proposed in 2017.With advantages of small structure and low energy consumption, LiCi is more suitable for resource-constrained environments such as the internet of things (IoT).In the design document of LiCi, the ability of LiCi algorithm to resist differential attack and linear attack is analyzed, but the resistance of LiCi algorithm to differential fault attack has not been discussed.According to the permutation law of each round iteration of LiCi algorithm, 32-bit key can be recovered by injecting a single bit fault into the left half of the 31st round iteration combined with its differential property.According to the key choreography scheme of the LiCi algorithm, the same differential fault attack was performed on iterations 30th, 29th, 28th, 27th and 26th round to recover all the original keys.The attack requires a total of 48-bit faults, and the computational complexity is 2<sup>32</sup>, which indicates the LiCi algorithm is difficult to resist differential fault attacks.…”
