摘要
To overcome the expensive pairing operations, pairing-free certificateless authenticated key agreement protocols have been put forward. But most of these protocols concentrated on efficiency and security of two-party key agreement schemes. In this paper, we put forward a pairing-free certificateless authenticated group key agreement protocol. In the protocol, there are no need for pairing operation and the signature for authentication. The protocol provides group key establishment and group key rekeying services for dynamic groups. Through analysis, the proposed protocol is secure and efficient.
