摘　　要：通过对美国太空安全挑战赛中AES破解挑战的分析,提出了使用AES缓存碰撞时间攻击的破译思路,分析了AES缓存碰撞时间攻击的原理,将密钥可能空间缩小至6700万,成功利用密钥已知部分推测出未知部分,最终实现该攻击,验证了AES缓存碰撞时间攻击的实践可行性。Through the analysis of the AES cracking challenge in the US space security challenge,this paper puts forward a decoding idea of using AES cache collision time attack,which reduces the possible space of the secret key to 67 million by analyzing the principle of AES cache collision time attack.This paper has successfully realized the attack by inferring the unknown part with the known part of the secret key,verifying the practical feasibility of the AES cache collision time attack.
