摘　　要：提出了一种基于随机延迟的高效的抗旁路攻击处理器结构,综合采用随机指令调度、随机指令注入和随机流水段延迟技术以抵抗旁路攻击.基于ARM7处理器实现了该架构,实现结果表明本处理器比原始ARM7处理器增加了约20%的硬件面积.通过相关系数分析攻击(Correlation Power Analysis,CPA)实验证明,采用本架构的处理器具备有极高的抗旁路攻击防护能力,可以应用在USBKEY、智能卡(Smart CARD)等高安全应用场合.In this article, based on random delay insertion, an effective processor architecture resistant to side- channel attacks was proposed. It used a combination of randomized scheduling, randomized instruction insertion and randomized pipeline-delay to resist side-channel attacks. On the base of ARM7 processor, we implemented this architecture and the implementation results showed that this processor has increased approximate 20O/oo in hardware area than the original ARM7 processor. The CPA attack experiment results suggested that our new secure processor have high capacity to resist side-channel attacks and thus could be used in USBKEY, Smart CARD and other application scenarios which require extremely high security level.
