A Trust Conscious Secure Route Data Communication in MANETS

Security in mobile adhoc networks is difficult to achieve, notably because of thevulnerability of wireless links, the limited physical protection of nodes, thedynamically changing topology, the absence of a certification authority, and thelack of a centralized monitoring or management point. The major difficulty inadhoc network occurs when a new node join network but not having any trustbased relation with other nodes of network. We have proposed a newmechanism that provides trust conscious secure route data communicationbetween the Mobile nodes. In this mechanism we will dynamically increase thetrust from (Low to High) between the mobile nodes using proxy node. Whenmobile node needs secure data communication, it will generate a dynamic secretsession key with the desired destination mobile node directly or via proxy mobilenodes. These dynamic secret session keys are generated using message digestand Diffie-Hellman protocol.
