A Secure Certificateless Authenticated Group Key Agreement Protocol
We present an efficient authenticated group key agreement (AGKA) protocol in certificateless public key setting (CL-AGKA). The protocol only needs two communication rounds. In each protocol run, only four pairing computations are involved for each participant. The authentication in our protocol is realized using a signature scheme which is provably secure in the strongest security model for certificateless signature (CLS) schemes where the type I/II adversary is a super type I/II adversary. The security analysis shows our protocol satisfies Key authentication, Known session key security, Key compromise impersonation security, Perfect forward security, and Known session-specific temporary information security.
