Abstract: In 2004, Long et al. proposed a new public key certification structure to implement a localised authentication scheme by modifying the SSL protocol v3.0. Their scheme keeps the user|s identity concealed and minimises the influence of the home network|s failure and the overhead of having the legal user authenticated by its home network. Unfortunately, the privacy of the roaming user and the round efficiency in Long et al.|s scheme are doubted. In this paper, the authors present an improved version conserving the advantages of Long et al.|s scheme, ensuring round efficiency and providing both mutual authentication and key agreement.

Keywords: roaming; public key certification; authentication; key agreement; SSL; mobile communications; user identity; privacy; security; efficiency; internet; wireless LANs; wireless networks.
