A Dynamic ID Based Authenticated Group Key Agreement Protocol from Pairing

摘要


In this paper we present an identity (ID) based dynamic authenticated group key agreement protocol. Our protocol satisfies all the required security attributes and also provide forward and backward confidentiality. The security of our protocol is based on the bilinear Diffie-Hellman(DH) assumption. We extend Lee et al. ID based authenticated key agreement protocol from two party to a group of users by using bilinear pairing.
