From Precise to Random: A Systematic Differential Fault Analysis of the Lightweight Block Cipher Lilliput
Peipei Xie, Siwei Chen, Zejun Xiang +2
At SAC 2013, Berger et al. first proposed the Extended Generalized Feistel Networks (EGFN) structure for the design of block ciphers with efficient diffusion. Later, based on the T…
Cryptanalysis of Gleeok-128
Siwei Chen, Peipei Xie, Shengyuan Xu +3
Gleeok is a family of low latency keyed pseudorandom functions (PRFs) consisting of three parallel SPN based permutations whose outputs are XORed to form the final value. Both Glee…
Enhancing Deep Learning-Based Rotational-XOR Attacks on Lightweight Block Ciphers Simon32/64 and Simeck32/64
Chengcai Liu, Siwei Chen, Zejun Xiang +2
At CRYPTO 2019, Gohr pioneered neural cryptanalysis by introducing differential-based neural distinguishers to attack Speck32/64, establishing a novel paradigm combining deep learn…
Constructions of Optimal Frequency-Hopping Sequences with Controlled Minimum Gaps
Chen Li, Chunlei Li, Xiangyong Zeng +1
Frequency-hopping sequences (FHSs) with low Hamming correlation and wide gaps significantly contribute to the anti-interference performance in FH communication systems. This paper…
Enhancing the MILP/MIQCP-based Automatic Search for Differential-Linear Distinguishers of Simon-Like Ciphers
Siwei Chen, Zejun Xiang, Xiangyong Zeng +1
In this paper, we propose an improved method based on Mixed-Integer Linear Programming/Mixed-Integer Quadratic Constraint Programming (MILP/MIQCP) to automatically find better diff…
Further Investigations on Nonlinear Complexity of Periodic Binary Sequences
Qin Yuan, Chunlei Li, Xiangyong Zeng +2
Nonlinear complexity is an important measure for assessing the randomness of sequences. In this paper we investigate how circular shifts affect the nonlinear complexities of finite…
