dc.description.abstract | ID-based group key agreement (GKA) has been increasingly researched with the advantage of simple public key management. However, identities of group members can be exposed in the ID-based GKA protocol, so eavesdroppers can easily learn who belongs to the specific group. Recently, Wan et al. proposed a solution for this problem, an anonymous ID-based GKA protocol, which can keep group members’ anonymity to outside eavesdroppers; nevertheless, the protocol has some security flaws. This paper shows that Wan et al.’s GKA is insecure against colluding attack and their joining/leaving protocols do not guarantee forward and backward secrecy. We also propose a new forward secure ID-based GKA with anonymity from enhancing Wan et al.’s joining/leaving protocols. Our scheme provides forward and backward secrecy and is essentially just efficient as Wan et al.’s scheme. | en |
