摘　　要：综述SPA和DPA攻击与防御技术的最新进展情况,在攻击方面,针对不同的密码算法实现方式,详细描述SPA、DPA和二阶DPA攻击技术.防御技术分别介绍了各种掩码技术、时钟扰乱技术以及基于双轨互补CMOS的功耗平衡技术,并分析了这些技术中的优缺点,最后对该领域未来可能的研究方向和研究重点进行了展望.This paper summarizes the latest development of SPA and DPA Attack and Defense techniques. Aimed at various implementation of cryptography, the attack methods including SPA, DPA and high order DPA are depicted and analyzed. Then the available countermeasures of power analysis are shown, which consist of MASK methods, timing disturbance and power equalization technique based on balanced load dual rail CMOS. Moreover, the relative merits of these countermeasures are analyzed. After this, the paper proposes some potential directions and key issues for the future research.
