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…
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…
On the second-order zero differential spectra of some power functions over finite fields
Yuying Man, Nian Li, Zejun Xiang +1
Boukerrou et al. (IACR Trans. Symmetric Cryptol. 2020(1), 331-362) introduced the notion of Feistel Boomerang Connectivity Table (FBCT), the Feistel counterpart of the Boomerang Co…
