This paper presents an authentication and key agreement mechanism for multi-domain wireless networks using bilinear pairings. Based on the computational Diffie-Hellman assumption and the random oracle model, we show that the proposed scheme is secure against an uncertified user and a malicious registration server simultaneously. As compared with the recently proposed schemes, our scheme enjoys less computational cost and has higher security level by exploiting the certificateless public key cryptography system. Moreover, our scheme can be used to mutual authentication and key agreement between members of distinct domains where all the servers use different system parameters. Efficiency analysis of related the security and computation overheads are given to demonstrate that our scheme is well suited for mobile devices with limited computing capability.
