SECURITY PROVIDED TO MOBILE AD-HOC NETWORKUSING RSA ? ASYMMETRIC KEY CRYPTOGRAPHY

Mobile ad hoc network (MANET) is a dynamic network consists of mobile devices connected together by wireless Network. Most of the time, the nodes in MANET are mobile and can request to connect or leave the network. As a result, the pathwill frequently change.The AODV is very wellknown protocol for MANNETFor most existing routing protocols of mobile ad hoc network (MANET), more efficient security mechanisms against the attacks from malicious nodes, authentication of nodes should be provided. Cryptographic algorithms can be used to provide security in MANNET.
