Secure AODV routing protocol using SL multi-signcryption

Routing security is an important issue in secure ad hoc networks, and it appears to be a problem that is not trivial to solve. In this paper, we consider secure routing protocol and applied new cryptographic mechanism: multi-signcryption to routing protocol for ad hoc networks. SL multi-signcryption scheme efficiently provides message flexibility, order flexibility, message verifiability, order verifiability, message confidentiality, message unforgeability, non-repudiation and robustness. It is suitable for protecting messages and multi-signers from malicious attacks in networks. For this reason, using SL multi-signcryption, we propose a new secure AODV (Ad hoc on-demand distance vecter) routing protocol: SCRP (Sign-cryption based routing protocol). SCRP indeed enhances the security of AODV routing protocol and provides confidentiality, integrity, authentication, and non-repudiation to the routing message. Moreover, compared with other secure AODV, SCRP provides some other advantages such as lower computational cost and communicational overhead, flexibility of route message, and partially anonymous route.
