A Group Authentication Model for Wireless Network Services Based on Group Key Management

Abstract

Group authentication provides authentication for members of communication group between services and users in insecure environments such as wireless networks. Most of the group authentication models do not consider the risk of compromised share secrets in the group under various security threats such as cryptanalysis. Although authentication key exchange in groups can benefit from group key management to minimise this risk, the group key management schemes are inefficient for authentication services. In this paper, a group authentication model for wireless networks services using a group key management is presented. The group key management is specially designed with forward secrecy and session keys for efficient and secure key exchange. Based on this secure session keys, a dynamic group authentication scheme provides a secure and efficient group authentication for wireless network users and services.
