Golden Linear Group Key Agreement Protocol

Security in group communication has been a significant field of research for decades. Because of the emerging technologies like cloud computing, mobile computing, ad-hoc networks, and wireless sensor networks, researchers are considering high group dynamics in communication security. Group key agreement protocol is for providing enough security for the group communication. Group key agreement protocol is a way to establish a shared cryptographic key between groups of users over public networks. Group key agreement protocol enables more than two users to agree on a shared secret key for their communications. In this paper we want to introduce a new key agreement protocol (GKA) and a new linear group key agreement protocol (GLGKA). These protocols are proper for the emerging dynamic networks. In GLGKA each member of the group can participate in key generation and management process. Our goal is to provide more efficient key generation approach for group members. This protocol can be used in cloudbased data storage sharing, social network services, smart phone applications, interactive chatting, video conferencing, and etc.
