摘要:

摘 要:等功耗编码算法是一种既能提高算法效率,又能提高抗功耗分析攻击安全性的算法,但由于伪操作设计缺陷,原型算法在全零段时存在抗攻击弱点。经过对伪操作重新设计的优化改进,算法的安全性得到进一步加强。同时还给出了一种使用蒙哥马利算法的快速算法实现,在进一步提高算法效率的同时,并未削弱其安全性。在功耗测试平台上的实测结果也验证了该改进算法抗功耗分析攻击的有效性。

关键词: 信息安全, 边信道攻击, 功耗分析攻击, 等功耗编码算法

Abstract:

Equivalent power consumption coding algorithm not only could improve algorithm efficiency, but also could be against the power analysis attacks.But it had weak in all-zero exponential segment because of a defect of pseudo-operation design.So a new pseudo-operation was proposed to improve the algorithm’s security.And a rapid implementation using Montgomery algorithm was presented too.It could accelerate the operation with no-lower safety.The research’s validity is proved in the real power testing platform.

Key words: information security, side channel attacks, power analysis attacks, equivalent power consumption coding
