A Novel Secure Communication Protocol for Ad Hoc networks [SCP]
Abstract: An ad hoc network is a self organized entity with a number of mobile nodes without any centralized access point and also there is a topology control problem which leads to high power consumption and no security, while routing the packets between mobile hosts. Authentication is one of the important security requirements of a communication network. The common authentication schemes are not applicable in Ad hoc networks. In this paper, we propose a secure communication protocol for communication between two nodes in ad hoc networks. This is achieved by using clustering techniques. We present a novel secure communication framework for ad hoc networks (SCP); which describes authentication and confidentiality when packets are distributed between hosts with in the cluster and between the clusters. These cluster head nodes execute administrative functions and network key used for certification. The cluster head nodes (CHs) perform the major operations to achieve our SCP framework with help of Kerberos authentication application and symmetric key cryptography technique which will be secure reliable transparent and scalable and will have less over head.
