摘要:

侧信道分析是密码系统的现实威胁之一。通过长期跟踪研究,对侧信道分析的主要研究方向,譬如信息预处理、非建模类和建模类分析等进行了分类总结,归纳了侧信道分析研究的核心内容,指出现有分析方法中存在的主要问题是依赖人为假设。人为假设一旦偏离实际情况,将会严重地影响侧信道分析的实际效果。给出了解决上述问题可能的技术路线,即使用零假设(弱假设)方法,并对该方向的后续研究进行了展望。

关键词: 侧信道分析, 信息预处理, 非建模类分析, 建模类分析, 零假设(弱假设)方法

Abstract:

Side-channel attack is among the real threats to a cryptosystem in practice.By tracking its latest development,the main research directions including information pre-processing,non-profiled and profiled analysis are classified and demonstrated.The research key points of side-channel attack are summarized,in which the limitation of relying on artificial assumptions is pointed out to be as the principal issue of the state-of-the-art methods.Once the artificial assumptions deviate from the actual situation,the effect of side-channel attack will be seriously affected or weakened.A possible technical solution to ruling out this limitation is given,that is,to make use of what we call the zero-assumption (or weak assumption) method.The next-step research points under this assumption are listed briefly.

Key words: side-channel attack, information pre-processing, non-profiled analysis, profiled analysis, method without (with weak) assumptions
