Abstract

AbstractWith the rapid development of mobile networks, there are more and more application scenarios that require group communication. Group communication can transmit messages to all group members with minimal resources. The security of group communication depends on the security of the group key. Most existing group key agreement protocols are often flawed in performance, scalability, or security. Therefore, this paper proposes a blockchain-based distributed authentication and dynamic group key agreement protocol. Based on blockchain technology, this protocol improves the scalability and makes it possible to track malicious members. In addition, comparison with related protocols shows that our protocol reduces computational and communication costs.KeywordsAuthenticationBlockchainCryptographyGroup key agreement
