Group communication mechanism provides several participants with a secure and credible communication environment by sharing a confidential group key within group members. Group Diffle-Hellman key exchange protocol (GDR) is an extension of two-party Diffie-Hellman key exchange. Many protocols based on GDH protocol have been proposed, among which AT-GDH protocol is an authenticated group key agreement protocol. AT-GDH2 protocol complements AT-GDH with a dynamic group key updating scheme. This paper proposes an improved dynamic scheme based on AT-GDH after analyzing the security flaws in AT-GDH2 protocol. We name this proposed group key management process as AT-GDH3. Then the security property of AT-GDH3 protocol is analyzed using the strand space and authentication test theory from the aspects of authentication, implicit key authentication, recency, backward security and forward security. The results show that AT-GDH3 protocol can overcome the security flaws in AT-GDH2 protocol, and can guarantee security properties of group key management. |
