安全性、易用性与加解密的效率是建构PKI客户端系统的重要内容。这些问题与密钥的管理、加密的硬件实现有关。文章就客户端密钥的管理方法与加密的专用硬件模块实现进行了探讨,并给出了一种具体的基于USB接口的客户端密码加速器的实现方案。
Security, ease of use and the efficiency of encryption and decryption constitute an important part of the PKI client system. These problems are related to key management and hardware implementation of encryption. The article discusses the management method of the client key and the implementation of the special hardware module for encryption, and gives a concrete implementation plan of the client password accelerator based on USB interface.
