摘要
随着计算机网络技术的发展,全球信息化已经得到了前所未有的发展,但随之而来的安全问题也日趋突出。公钥基础设施(PKI)作为一套完整的Internet安全解决方案,现已成为信息安全技术的核心,同时它也是电子商务的关键和基础技术。从网络信息安全的需求出发,基于PKI的非对称密钥加密,结合数字签名、身份认证、数字证书等安全技术,构建了基于USBKey的身份认证系统,并将它应用于实际系统,已取得了良好的效果。
Along with the development of the computerized network technology, global information sharing reaches an unprecedented level, while the problem of information security becomes glaring accordingly. As an integrated set of Interact security solution, public key infrastructure ( PKI ) has been formed the kernel of information security technology. In addition, it becomes the critical and basic technology of electronic commerce. From the requirements of network information security, based on PKI asymmetric encryption and combining with the technologies of digital signature, identity authentication, digital certificate, the system of identity authentication based on USB Key is created and used in practical applications with excellent result.
