基于比特可分性的BORON和Khudra积分区分器搜索.

This paper evaluated the integral properties of BORON cryptography algorithm with SPN structure and Khudra cryptography algorithm with Feistel structure. It estahlished MILP model based on bit-based division according to the structure of linear layer and nonlinear layer. It generated the corresponding objective function according to the number of target rounds in the final search, and utilized the optimizer of Gurobi to solve the model and searched the distinguisher. Finally, it obtained the 6-round integral distinguisher of BORON and the 7-round integral distinguisher of Khudra, which were the longest distinguishers at present. By using these distinguishers, more rounds of assessment of integral properties can be carried out [ABSTRACT FROM AUTHOR]
