DAAODV: A Secure Ad Hoc Routing Protocol Based on Direct Anonymous Attestation

Many approaches have been proposed to secure various ad hoc routing protocols. However, many attacks such as wormhole attacks, vertex cut attacks, and traffic-analysis based attacks are still not well addressed. In this paper, we propose a novel secure routing protocol DAAODV which is based on ad-hoc on-demand distance vector routing (AODV). DAAODV takes full advantage of trusted computing technology, particularly the direct anonymous attestation (DAA) and property-based attestation (PBA) protocols. DAAODV is an anonymous protocol without requirement of trusted third party (TTP). Moreover, we propose an efficient signing and verification scheme to overcome the potential DoS attacks triggered by the low efficiency of DAA and PBA. In the simulation, the results show that DAAODV is still efficient in discovering secure routes compared with AODV protocol.
