AODV Routing Protocol, Digital Signature, One-way Hash Function, Double One-way Hash Verification


For most existing routing protocols of mobile ad hoc network (MANET), more efficient security mechanisms against the attacks from malicious, compromised and selfish nodes are highly demanded. This paper proposes a series of security mechanisms for the Ad-hoc On-demand Distance Vector (AODV) Routing protocol. Three techniques, including digital signature, one-way hash function and double one-way hash verification are introduced to ensure the authentication, nonrepudiation and integrity of the important routing information in AODV protocol. The comparison with some existing secure AODV protocols demonstrates that our solution expands the security scope and guards against several attacks out of their range.
