| 摘 要： | 提出将掩码和随机延时两种策略综合的方法以增强加密算法的抗攻击性能, 同时, 提出一种多掩码方案取代传统的单一掩码, 进一步增强抵御以汉明重量为模型的能量攻击。此综合策略应用于DES加密设备, 结果表明, 能够成功抵御105条能量迹攻击, 抗攻击性能提高40%。

| Abstract: | The authors propose a novel countermeasure which associates masking with RDI (random delay in- sertion). Further, multi-masking instead of transformed masking is proposed in order to defend DPA (differential power analysis) attack based on Hamming distance model. The combined countermeasure is implemented on Data Encryption Standard. The results show that combined countermeasure can defend DPA attack with 105 power traces, and increase 40% ability against DPA attack. |
