An efficient cryptographic mechanism to defend collaborative attack against dsr protocol in mobile ad hoc networks

Abstract

This paper presents a novel mechanism to defend and detect the collaborative attack against popular DSR using Elliptic Curve Digital Signature Algorithm (ECDSA). This proposed security mechanism is suitable for sophisticated wireless ad hoc network that provides efficient computation, transmission and very powerful against collaborative attack. Already, several secure routing protocols were proposed to defend the attacks. However, most of the security mechanisms were used to detect or defend the single or uncoordinated attacks.
