摘　　要：为评估ARIA密码抗Cache计时攻击安全性,提出了一种访问驱动Cache计时模板分析模型,给出了直接分析和排除分析2种模板匹配方法.以ARIA分组密码为例,给出了前4轮模板攻击方法,并通过本地攻击实验验证理论正确性.结果表明:ARIA易遭受访问驱动Cache计时模板攻击,应用直接模板分析和排除模板分析方法,200个样本均可在1s内恢复ARIA 128bit密钥.模板分析模型还可为其他使用S盒的分组密码访问驱动Cache计时模板分析提供一定参考.In order to evaluate the security of ARIA against Cache timing attacks, an access driven Cache timing template attack model was proposed, non-elimination or elimination two template matching method were given. Taking ARIA as an example, the first 4 rounds template attack method was presented, which was verified through the experiments. Experiment results demonstrate that ARIA is vulnerable to access driven Cache timing template attack, by applying the non-elimination or elimination template matching method, 200 samples are enough to obtain the 128 bit master key within 1 s. Meanwhile, the template analysis model can provide some ideas to access driven Cache timing template attacks against other block ciphers using S-box.
