Trust Based Packet Forwarding Scheme for Data Security in Mobile Ad Hoc Networks
In Mobile Ad hoc NETworks (MANET) threats is a major concern and most routing protocols are based on authentication, security association, key distribution and so on. The authors require a network-level or link layer security. Since without appropriate security provisions, the mobile adhoc networks are subjected to attacks like network traffic, replay transmissions, manipulate packet headers and redirect routing messages. In order to overcome these problems trust based packet forwarding scheme is suggested for mobile ad hoc network system that provides the capability to express network requirements. In this paper, they propose a trust based scheme for combined data security which focuses mainly on integrity and authentication.
