| 摘 要： | 为了发现可用于能量攻击的硬件实现与算法体制的安全漏洞,全面评估流密码算法MICKEY的安全系数, 给出了一种差分能量攻击方案.基于MICKEY硬件实现简单和抵抗传统攻击技术的事实,它以三输入异或部件为切入点,通过分析其寄存器R和S的能量消耗和统计特征,发现了反馈值与能量消耗之间的关系,并通过软件仿真证实了密钥比特猜测正确和错误时峰值的显著差异.模拟攻击结果显示,获得MICKEY全部80 b密钥只需48 s.得出了所给出的能量攻击方案有效且可行的结论.

| Abstract: | In order to seek security vulnerability of hardware realization and the algorithm system for power analysis attack and get a thorough understanding about the security coefficient of MICKEY,a differential power attack algorithm was proposed.Based on its simple hardware realization and resistance to traditional technologies,the three-input-XOR unit was taken as the breakthrough point.By analyzing the consumed power and the statistical characteristics of the register R and S in MICKEY,the correlationship betwe... |
