WLAN Authentication Scheme Based on Message-Recovery RSA-PSS

In this paper, a wireless local area network (WLAN) authentication scheme is proposed to both enhance the security and the working efficiency of the network. The authentication sever (AS) and the mobile terminals are properly configured with different workloads of signature generations and signature verifications. We propose using the RSA-PSS-MR scheme and the improved ElGamal scheme. Firstly, the Recovery features of the RSA-PSS-MR scheme have reduced the communication bandwidth sharply since the public keys are not necessary to transmit in our scheme. Secondly, the asymmetry calculation of signature generations and verifications of the improved ElGamal scheme can be well used to configure the scheme. The proposed scheme resolves the real-time transmission problem of authentication.
