Analysis and improvement of a password-based authenticated key exchange protocol
The security of a recently proposed password-based authenticated key exchange protocol was analyzed. Al- though it was provably secure in the standard model, it was vulnerable to reflection attacks. A modify scheme was pro- posed, which eliminated the defect of original scheme and improved the effic...

| description | The security of a recently proposed password-based authenticated key exchange protocol was analyzed. Al- though it was provably secure in the standard model, it was vulnerable to reflection attacks. A modify scheme was pro- posed, which eliminated the defect of original scheme and improved the efficiency of the protocol. The security of the proposed scheme had been proven in the standard model under DDH assumption. The results show that it provides per- fect forward secrecy. |
