| Abstract: |
| Information Security has influenced political, military, economic, cultural and many other fields of a country. Information is generally stored and processed in computer system. The core component of a computer system is CPU (central processing unit). Therefore, CPU security is the basis of both computer system security and information security. Security processors are used in such industries as trusted computing, industrial control, identity recognition, network communication and e-payment. After summarizing the security processor development process, this paper classifies key processors according to application scenarios. Combining the specific function and security processor architecture, it analyzes the features and shortcomings of main security processor technology and finds out the rules in security processor research. Finally, it offers research direction to the security processor. |
