Abstract: Authenticated group key agreement problem is important in many modern collaborative and distributed applications. There are two ID-based authenticated group key agreement schemes have been proposed by Choi et al. and us, which are based on bilinear pairings and BD scheme. Recently, Zhang and Chen propose an impersonation attack on the two schemes, which means the schemes are not fully authenticated. In this paper, we propose an improved ID-based authenticated group key agreement scheme which can resist this attack.
