【摘要】 身份验证是网络安全最重要的一道防线.首先介绍了椭圆曲线密码体制(ECC),讨论了静态口令和三种动态口令身份认证机制,然后探讨了指纹识别技术,并比较了它们的优缺点.在此基础上,提出了基于ECC的增强型双因子身份认证系统,设计了系统的软件体系结构,阐述了各模块的功能.双因子身份认证的目的是将动态口令和用ECC加密的指纹技术有机地结合起来,进一步增强客户端身份认证的强度.实践结果表明,该系统提高了身份认证的可靠性和安全性,并达到双重认证的效果.更多还原

【Abstract】 Identity authentication is the most important line of defence in the network security.At first,ECC is introduced,identity authentication mechanisms of static password and three dynamic passwords are discussed,then fingerprint identification technology is explored,at the same time compares their advantages and disadvantages.On this foundation,A strong double-genes authentication system based on ECC is put forward,software architecture is designed and each module’s function is set forth.The purpose of double-genes authentication is to enhance intensity of client identity authentication by combining dynamic password with used ECC fingerprint technology.Practice results show this system improves the reliability and security of identity authentication,meanwhile realizing the double identity authentication.更多还原
