A MANET (Mobile Ad-hoc Network) is an infrastructure-less self configuring wireless networks of routers. Key management is at the center of providing network security via cryptographic mechanisms with a high-availability feature. Dynamic key is the efficient assistance for network scalability. Routing protocol used here is a form of reactive routing called CA-AOMDV and compared with Table driven routing called DSDV. Channel aware routing protocol quality of the channel which can be measured in terms of suitable metrics. This paper leads to an emphasis on Black hole attack and to develop a dynamic key framework using RSA algorithm.
