AES-192的相关密钥飞去来器攻击和矩形攻击
Related-Key Boomerang and Rectangle Attacks on AES-192
摘要
Abstract
Related-key attack is one of the most effective methods on AES.At Asiacrypt 2022,Derbez et al.gave the best attack on full AES-192 utilizing a 10-round related-key Boomerang distinguisher with the probability of 2-108.This paper improves the related-key Boomerang and rectangle attacks on full round AES-192.Based on the same truncated differential of Wang et al.'s 9-round related-key Boomerang distinguisher,a 10-round related-key Boomerang distinguisher can be computed with the probability of 2-105.92 by using the BDT technique.Based on the distinguisher,the related-key Boomerang attack on full round AES-192 can be improved to have time,data and memory complexities of 2121.92,2121.92 and 290.92 respectively,where the time complexity is reduced by a factor of 22 08 compared with the previous attacks.Furthermore,a related-key rectangle attack on full round AES-192 is given with the time,data and memory complexities of 2127.9,2119.5 and 2131.5 respectively,which is also the best result known so far in the chosen-plaintext setting.关键词
