A password based authentication protocol for access control in WLAN

WLAN technologies are becoming popular and the device are widely used everywhere nowadays, so more attentions are paid to when it comes to wireless security. Since the current security protocol in IEEE 802.11 namely wired equivalent privacy is known to be quite insecure, the IEEE 802.1x and IEEE 802.11i were proposed to resolve some problems in 802.11. However, the 802.1x still have some drawbacks and could be hijacked through middle of communication session. In this paper, we proposed a password-based authentication and key exchange protocol suitable to construct a secure connection for regular communication security. To overcome the drawback of password-based protocols causing by short length and randomness of password, the proposed protocol uses the signature techniques of ECDSA and the authentication protocol SRP based on Diffie-Hellman key exchange method.
