Deniable authentication protocol enables a receiver to identify the true source of a given message, but not to prove the identity of the sender to a third party. This property is very useful for providing secure negotiation over the Internet. This paper describes a secure non-interactive deniable authentication protocol using ECDSA signature scheme. The security of the protocol is based on difficulty of breaking elliptic curve discrete logarithm problem. It can be implemented in low power and small processor mobile devices such as smart card, PDA, etc. which work in low power and small processor.
