Abstract: Authenticated key agreement protocol allows a group of users in an open network environment to identify each other and share a security session key. This article proposed a new scheme of ID-based authenticated multi-party key agreement based on McCullagh-Barreto scheme. Key seed was introduced to update temporary public/private key pairs. The new scheme is able to realize the authentication, improve the security, resist Reveal query attack and the key compromise impersonation attack successfully, and it has many properties such as non-key control and equal contribution.

Key words: bilinear pairing, multi-party key agreement, authentication, BR93 model, Reveal query
