Cryptochip is an important carrier of information storage, processing and transmission. Its security in bypass environment has increasingly become an urgent problem to be solved in various application fields. Analyzes the security threats faced by cryptographic chips, and summarizes the main contents involved in the field of existing bypass analysis. Focus on several common bypass divider, including simple energy analysis, stencil analysis, differential analysis and correlation analysis, and compare their respective characteristics. Summarizes the security measures taken by the password chip in the bypass environment, and finally discusses the research direction in the next step.
