摘要：

为了成功实现对RSA密码芯片的破解,从密码芯片的功耗泄漏机理入手,研究了差分功耗分析理论,针对RSA密码算法进行了差分功耗分析实验,验证了差分功耗分析对破解RSA密码算法的可行性,并提出了基于随机扫描的掩模模幂算法作为抵御差分功耗分析的防护措施。

关键词: 功耗泄漏, 差分功耗分析, RSA芯片, 防护措施

Abstract:

To carry out the attacks of RSA CMOS(Complementary Metal Oxide Semiconductor) chips, the paper has investigated the theory of the differential power analysis based on the power consumption of cipher chip. And taking the RSA cipher algorithm as goal, the paper has finished the experiment of the differential power analysis attack.The paper proposes a randomized masking method as countermeasure.

Key words: power consumption, differential power analysis, RSA, countermeasures
