Mutual Authentication and Updating the Authentication Key in MANETS

Mobile Ad hoc Networks (MANETs) are new wireless networks with a self-configuring and self-maintaining topology, also characterized as dynamic topology. The architecture in MANETs has been introduced few years ago and its main characteristic is that it does not rely on any fixed infrastructure. These features bring in security vulnerabilities and also make it difficult to ensure security services to MANETs. To counteract this problem major research has been done. This article will talk about the approaches that intend to develop security schemes to MANETs and to create a defense against various attacks at different layers. Routing is a very important function in MANETs. It can also be easily misused, leading to several types of attack. This article proposes a scheme to improve and support mutual authentication and encrypt communication between the nodes in the MANET. The authentication scheme proposed is seeking to solve the security and privacy issues between any two communicating nodes in the MANET.
