一种抗侧信道攻击的随机功耗方法

摘要

针对RSA密码算法的实现电路有多种攻击方法.功耗平衡技术常用来抵抗侧信道攻击.为了解决抗侧信道攻击算法中开销大的问题.通过混淆比特位为0运算单元之间的功耗,提出一种随机功耗方法来抵抗侧信道攻击.通过对该方法的分析,证明该随机功耗算法能够实现抗计时攻击和能量攻击的目的,功耗能够减少30%左右,且不降低方案的安全性.%The implementation of RSA cryptosystems has a variety of attack methods.Equivalent power consumption is often used to resist the side channel attacks.In order to solve the problem of high cost problem against side channel attack algorithms,we proposed random power consumption to against the side channel attacks by confusing the power consumption of the 0 bit arithmetic units in this paper.Through the analysis of the method, it was proved that the stochastic power consumption algorithm achieved the purpose of anti-clock attack and energy attack, and the power consumption was reduced by about 30%without reducing the security of the scheme.
