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.
