Novel Efficient Deniable Authentication Protocol
LI Ming-xiang · Journal of Chinese Computer Systems · 2008
Data origin authentication can be classified as deniable authentication and non-deniable authentication.In recent years,many efficient non-deniable authentication protocols have been proposed.However,much less attention is on the deniable authentication.This paper is mainly focused on the research of deniable authentication.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 important for many special applications over the Internet.In this paper,some typical protocols previously proposed are briefly reviewed and several disadvantages are pointed out such as interactive,less efficient and security deficiency and so on.Finally,a novel deniable authentication protocol efficient and robust in security is put forward.
