安全处理器研究进展

信息安全已经影响到一个国家的政治、军事、经济和文化等诸多领域。信息一般在计算机系统上存储和处理。计算机系统的核心器件是处理器，所以处理器的安全是计算机系统安全的基础，也是信息安全的基础。在可信计算、工业控制、身份识别、网络通信、电子支付等许多行业，都要用到安全处理器。文章对安全处理器发展过程进行了梳理，并根据应用场景、功能进行了分类，结合具体安全处理器架构，分析了各主要安全处理器的技术特点和不足之处，找出安全处理器研究中的规律。最后，总结全文，对安全处理器的研究进行了展望。

Research Progress on Security Processor

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.
