A secure Deniable Authentication Protocol based on Bilinear Diffie-Hellman Algorithm

Jayaprakash Kar and Banshidhar Majhi

Abstract: This paper describes a new deniable authentication protocol whose security is based Diffe-Hellman (CDH) Problem of type Decisional Diffie-Hellman(DDH) and the Hash Diffie-Hellman (HDDH) problem.This protocol 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. A 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. Our proposed protocol will be achieving the most three security requirement like deniable authentication, Confidentialities and also it is resistant against Man-in middle Attack

Category / Keywords: cryptographic protocols / deniable authentication, ECDLP, ECDHP, HDDH, Bilinear pairing.
