• The goal of password-based authenticated exchange protocol is established secure key by using pre-shared human-memorable password. Most of existing schemes either have computation burden or rely on the random oracle model. A new scheme without random oracles is proposed, which requires only one generator. Due to not using CPA or CCA2 public encryption scheme, the proposed protocol is efficient in computational cost and simple in protocol description when compared other solutions without random oracles. Specifically, this protocol reduces 64% of the exponential computations of the protocol proposed by Yin Yin et al. in the paper of "Provable secure encrypted key exchange protocol under standard model". The security of the proposed scheme has been proven in the standard model under DDH assumption.
