Differential Fault Analysis of Lilliput under Random-Location Nibble Faults
Peipei Xie, Siwei Chen, Zejun Xiang +2
Lilliput is a lightweight block cipher based on a Type-2 Extended Generalized Feistel Network (EGFN). Although it has been studied under conventional cryptanalytic techniques, its…
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…
