Abstract

Abstract: Mobile Ad-hoc Networks or MANETs are mostly found where any fixed facilities are not available and so it is dynamic. Secure transmission of data is an important aspect in MANET. They have unique characteristics like dynamic topology, wireless radio medium and lack of centralized administration. As a result they are vulnerable to different types of attacks in different layers of protocol. To protect these networks, various security protocols have been developed. To address these issues, a framework called Security Using Pre-Existing Routing for Mobile Ad-hoc Networks (SUPERMAN) [ 1 ] is proposed. This paper presents a security framework SUPERMAN which enables data confidentiality and prevention of data loss by using AES encryption. And a report is generated at the destination side to view user details, path details and attack node details. Keywords: mobile ad hoc networks, node authentication, data confidentiality.
