Nowadays chaos theory related to cryptography has been addressed widely, so there is an intuitive connection be- tween group key agreement and chaotic maps. Such a connector may lead to a novel way to construct authenti- cated and efficient group key agreement protocols. Many chaotic maps based two-party/three-party password au- thenticated key agreement (2PAKA/3PAKA) schemes have been proposed. However, to the best of our knowl- edge, no chaotic maps based group (N-party) key agree- ment protocol without using a timestamp and password has been proposed yet. In this paper, we propose the first chaotic maps-based group authentication key agree- ment protocol. The proposed protocol is based on chaotic maps to create a kind of signcryption method to trans- mit authenticated information and make the calculated consumption and communicating round restrict to an ac- ceptable bound. At the same time our proposed protocol can achieve members’ revocation or join easily, which not only refrains
