MPG-STAR: Mobile Process Groups Based Secured and Trusted Routing for MANets

Abstract

Wireless medium is more prone to security breaches than wired medium. The issue of security becomes critical in Mobile ad-hoc networks (MANets), due to the mobility of nodes. Node mobility causes frequent change in the radio transmission range thus changing the group membership. Members in a group communicate using the group key. Each time the group change, a new group key is to be computed in a secured manner providing backward and forward secrecy. This paper presents a secured and trusted routing algorithm MPG-STAR. The new group key is computed securely for trustworthy nodes of MPG routing protocol based on the ring based co-operation in Group Diffie-Hellman key exchange to avoid malicious or selfish nodes.
