Pairing-Based One-Round Tripartite Key Agreement Protocols

Since Joux published the first pairing-based one-round tripartite key agreement protocol [12], many authenticated protocols have been proposed. However most of them were soon broken or proved not to achieve some desirable security attributes. In this paper we present two protocol variants based on Shim [19] and Zhang et al.’s work [23]. As the formalized model of this kind of AK protocols is not mature, the security properties of the protocols are heuristically investigated by attempting a list of attacks described in the literature and presented as a reference, that can be used to evaluate other protocols.
