| 摘 要： | 为提高网络应用系统的安全性,同时降低系统升级的成本和复杂性,提出了一个基于公钥基础设施(PKI)和U盘的身份认证系统.在系统设计中,以PKI安全体系为基本框架,采用“挑战/应答”协议实现对用户身份的有效确认,使用普通U盘作为数字证书的载体,同时结合双因子验证机制,不但大大节省了应用系统的升级费用,而且保证了数字证书的移...

| Abstract: | To improve the security of network applications and reduce the cost and complexity of system upgrades,an authentication system based on public key Infrastructure(PKI) and U-disk is proposed.In the design of this system,PKI security system is used as the basic framework,and the Challenge/Response protocol is adopted to achieve an effective authentication.Common U-disk is used as the carrier of digital certificates and dual key approach as authentication mechanism,which not only saves the cost of application ... |
