The deniable authentication protocol is a new technique of modern cryptography, compared with traditional authentication, it has two characteristics; first, a receiver can verify the SCE of the message as in the traditional authentication protocol. Second, a receiver cannot prove the SCE of the message to a third party. In 2005, Wang et al. proposed an efficient deniable authentication protocol (WLT), which makes of the inverse of the ElGamal cryptosystem. It requires less computational complexity and communication cost.
