摘要
针对AES的差分故障攻击(DFA)过程,总结出对AES的DFA攻击算法与攻击模型的特点,在此基础上为AES密码芯片设计了一种基于TRC校验的防护电路,并对其抗差分故障攻击的可行性进行了仿真验证。结果表明,该防护电路能够快速准确地检测出导入错误,增强了AES芯片抗DFA攻击的能力。
Differential fault attack against AES is analyzed, and then an attack algorithm together with characteristic of attack models is summarized. On the ground of the previous works, a TRC based protection circuit is designed for AES crypto-chip, and its validity is proved through simulation. The result shows that the protection circuit can detect the abnormal faults quickly and accurately, thus greatly enhancing the capability of AES crypto-chip to resist DFA.
