Abstract

In 2010, an efficient authentication protocol has been proposed for virtual subnets on Mobile Adhoc Networks (MANET). It uses virtual subnet and each node in the subnet is authenticated using certificate. Further, it is claimed that protocol is robust, more efficient and practical. However, it is not suitable for devices have low computation power like mobile, PDAs, smart cards because number of computations are more in RSA based cryptosystem. In order to reduce the number of computation with same level of security, this paper proposes the same scheme using Elliptic Curve Cryptography (ECC) (modified scheme). Our scheme uses ECC in place of RSA to reduce number of computations with shorter key size.
