A Lightweight Group-Key Management Protocol for Ad Hoc Networks

Based on distributed key management, the trust mechanism of the local group, zero-knowledge proof and timestamp exchange mechanism of OLSR routing protocol, a new lightweight and robust group-key management protocol for Ad Hoc Networks is proposed. the protocol achives the advantages of low energy consumption, high efficiency and high availability by reducing both the number of control messages and the energy spent with cryptographic operations. Then, we demonstrates the security and anti-offensive of the protocol through safety analysis. Finally, simulation results show that the proposed protocol can ensure the security of Ad Hoc networks with a very low-impact on the performance of secure routing protocol.
