The greatest challenge for the MANETS is to come with a robust security solution even in the presence of malicious nodes, so that MANET can be protected from various routing strikes. Several countermeasures have been proposed for these routing strikes in MANETS using various cryptographic techniques. But most of these mechanisms are not considerably suitable for the resource constraints, i.e., bandwidth limitation and battery power, since they results in heavy traffic load for exchanging and verification of keys. In this paper, a new semantic security solution is provided, which suits for the different MANET constraints and also is robust in nature, since it is able to identify and prevent four routing strikes parallel.
