An OTP Scheme Based on Diffie-Hellman Key Exchange Protocol

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.
