A trusted connection based scheme for Ad Hoc network

摘要

Wireless Ad Hoc network is vulnerable to attacks due to its open and decentralized properties. This paper proposes a trusted connection based scheme for Ad Hoc network to prevent attacks. A trusted architecture is introduced into the node platform, which consists of two phases, platform identity verification and platform integrity measurement. For a communication requirement of two nodes, the terminal platform identity is firstly authenticated via Direct Anonymous Attestation, and the platform integrity measurement is performed for the nodes passing authentication. The communication is established if the nodes in both sides pass the authentication and measurement. We conduct simulation experiments to analyze the performance of the proposed scheme and verify its security in the attack scenario. The simulation results show that the proposed scheme can prevent the malicious nodes from accessing the network and resist the attacks from network.
