摘要
分析了常见的几种一次性口令身份认证方案,提出了一种基于Diffie-Hellman密钥交换协议OTP方案。该方案不仅能够有效地保护用户的身份信息,而且安全性好,执行效率高,能提供通信双方的相互认证,能防止假冒攻击、中间人攻击、重放攻击等多种攻击方式。最后对该方案的安全性进行了剖析。
Several common one-time password identity authentication schemes are analyzed.An OPT scheme based on Diffie-Hellman key exchange protocol is put forward.The scheme not only can protect the user s identity information effectively,but also has good safety and high executive efficiency.It can provide mutual authentication between both sides of communication,prevent fake attack,man-in-the-middle attack,replay attack,etc.Finally,the security of the scheme is analyzed in detail.
