分组密码 PRESENT算法基于MI LP的分析
Analysis of PRESENT block cipher based on MILP
摘要
Abstract
CHES2007 proposed a lightweight block cipher algorithm is PRESENT algorithm.The key is divided into two ver-sions,such as 80 bit and 128 bit,the attacker uses a variety of methods including the impossible differential analysis to its analysis.This paper used mixed integer linear programming (MILP),and frequently used this method in business and eco-nomics to solve optimization problems.This technique significantly reduced the workload of designers and cryptanalysts.This paper used this method to analyze the PRESENT algorithm,used the MILP method to get the optimal solution of the PRESENT algorithm which was the impossible differential characteristic.关键词
