A collaborative approach to secure ad hoc routing protocols

Abstract

Most of the secure ad hoc routing protocols are based on cryptographic solutions whose drawback is to decrease the network performances. In this paper, we propose a secure routing scheme for the DSR protocol. The proposed scheme combines the hash chains and digital signatures to provide a high level of security while reducing the costs of hop-by-hop signature verification. The proposed protocol is analyzed regarding its security. Several scenarios are used to demonstrate its efficiency in presence of attacks.
