Enhancement of mobile ad hoc network security using improved RSA algorithm

Abstract

The RSA algorithm is used in different communication networks in order to ensure data confidentiality. This paper proposed an improvement in RSA algorithm for the increased security enhancement in mobile ad hoc network. The proposed method is best for small messages and also applicable for much increased data security in different types of network including new generation network. For large volume of data, we have added DES with proposed RSA and getting better and secure transmission. We have used key length up to 2048 bits considering better security, computing speed, and processor condition. Key length can be increased depending upon the conditions. © Springer Science+Business Media Singapore 2016.
