ID-Based Non-interactive Deniable Authentication Protocol

Noninteractive deniable authentication protocol is vulnerable to the receiver key compromise impersonation attack, which are owing to the reason that the authentication message is computed from the receiver´s private and some other public values. Consequently, in order to be suitable for evaluation the security of noninteractive deniable authentication protocol, we have to redefine the attribute of key-compromise impersonation as the attribute of sender key-compromise impersonation, then proposes an simple and efficient ID based noninteractive deniable authentication protocol. The proposed protocol has no need for use of an additional signature to provide extra authentication, and satisfies authenticity, deniability and sender key-compromise impersonation security attributes simultaneously.
