Anonymity-Based Authenticated Key Agreement with Full Binding Property

摘要

In this paper we propose anonymity-based authentication and key agreement protocols where no participant's identity is revealed. The proposed protocols guarantee stronger notion of security which is called full binding property for communication messages. Under the notion of full binding, a verifier can confirm that an anonymous participant has not turned over a session to another anonymous participant while connecting to the verifier and also a session hijacking does not happen. Our approach is to use an anonymous signature scheme with a signer-controlled yet partially enforced linkability. We formally prove that the constructed protocols are secure.
