Blockchain-Based dynamic group key agreement Protocol for Ad Hoc Network

group key agreement(GKA) is one of the key technologies for ensuring information exchange security among group members. While GKA is widely used in secure multi-party computation, safety of resources sharing, and distributed collaborative computing. It still has some security flaws and limitations. We proposes a Blockchain-based dynamic group key agreement(BDGKA) protocol. In contrast to prior works, BDGKA differs in several significant ways: 1) anonymous identity authentication-it can prevent privacy leaks; 2)traceability-it can track illegal operating entities; 3) load balancing-it balances computation and communication to each node, avoiding the breakdown of single-point and network bottlenecks. This protocol is proven secure under the hardness assumption of decision bilinear DiffieHellman. The performance analysis shows that it is more efficient than the referred works.
