Enhanced Security Key Management Scheme for MANETS
Authors: , ,
Abstract: (MANET) Mobile Ad hoc Network is a collection of wireless infrastructure less network. The topology of the network changes continuously. Due to the dynamic structure of MANETs, they are prone to various types of attacks. The traditional security solutions for MANETs are inadequate, hence security should be maintained at all the levels. To enhance security various schemes have been proposed. In this article the security is provided by two schemes namely the elliptic curve cryptography and the digital signature algorithm. Various points are generated from the elliptic curve of prime field and a point is chosen at random as a secret key. The public key generation centre forms the secured channel for transmitting the secret key to all the users in the MANET. Now the secret key to be shared is encrypted using the RSA algorithm. The keys before sending and receiving must be signed by the sender and verified by the receiver thereby authenticating each other. The encrypted secret key is concatenated along with the signature pair key and is sent through the secured channel. Thus the security is enhanced at various levels which prevent strong malicious attacks.
