摘要: 提出一种抗差分功耗分析攻击的高级加密标准(AES)异步S盒电路。采用复合域算法实现精简的S盒结构,通过引入单轨异步流水线降低整个S盒的功耗,在单轨电路中局部采用异步双轨电路,利用随机数控制下的数据扰乱机制,改善电路的抗差分功耗分析攻击性能,建立S盒差分功耗分析攻击仿真平台,对设计的相关性能进行了仿真验证和测试。

Abstract: This paper proposes an asynchronous Advanced Encryption Standard(AES) S-box circuit with the performance of anti-Differential Power Analysis(DPA) attacks. In this S-box, composite-field arithmetic is used to attain the compact S-box architecture, the single-rail asynchronous pipelines are inserted in the data-path circuits to reduce the S-box circuit’s power, its property of anti-DPA attack is improved by introducing the locally inserting asynchronous dual-rail circuits and the disordered-data mechanism. Simulating validation and test are done by the presented simulating DPA attack platforms for the S-box.

Key words: Differential Power Analysis(DPA), Advanced Encryption Standard(AES), S-box, disordered-data mechanism
