%X To achieve security in a dynamic collaborative peer group, group key agreement protocol should be provided. Two-party key agreement protocol based on the weil pairing protocol (A-WGKA2) was proposed in this paper. It may establish a secret key between two nodes and authenticate each other by fewer messages. The proposed protocol has the security properties such as forward secrecy, no unknown key-share, known session key security, no key control and no key-compromise impersonation. Further, we proposed a group key agreement protocol using weil pairing referred as A-WGKAn that was adapted to the dynamic collaborative peer groups. In the A-WGKAn protocol, the A-WGKA2 protocol was employed on key tree to establish and allocate group key. Therefore, it not only has low computational overhead and communication costs but also provides the node authentication.
