| 摘 要： | 对PRESENT分组密码抗相关功耗分析能力进行了研究。基于汉明距离功耗模型，提出了一种针对PRESENT S盒的相关功耗分析方法，并通过仿真实验进行了验证。结果表明，未加防护措施的PRESENT硬件实现易遭受相关功耗分析威胁，5个样本的功耗曲线经分析即可恢复64位第一轮扩展密钥，将80位主密钥搜索空间降低到216，因此，PRESENT密码硬件实现需要对此类攻击进行防护。

| Abstract: | The correlation power analysis attack against PRESENT was discussed in this paper.An correlation power attack method according to the sbox in PRESENT cipher was presented based on hamming distance power leakage mo-del.The results of experiment indicate that hardware implementation of PRESENT without protection measure is vulnerable to correlation power analysis attacks.The 64-bit first round expanded key can be recovered with 5 power traces,and the 80-bit PRESENT master key searching space can be reduced to... |
