Secure Transmission in MANET using Threshold signature scheme

Jeevan Yadav N S , Sindhu Anand

Abstract The Adhoc network consists of mobile nodes which communicate with each other through wireless medium without any fixed infrastructure. Mobile Ad-Hoc Network (MANET) is a temporary self-organization, autonomous and decentralized infrastructure-free network which provides communication between two or more mobile nodes in situations where environmental constraints are difficult to setup any wired infrastructure and demand totally distributed networks. Due to their wireless links and lack of central administration MANET are vulnerable against adversarial attacks. MANETs have far greater security concerns than conventional networks. MANET must provide various levels of security guarantees to different applications for their successful deployment and usage. As MANET have highly dynamic topology that requires reliability and scalable security mechanisms. Security vulnerabilities in MANETs offer a number of unique properties that offer considerations when determining trust: Self-organization means they are autonomous, with no fixed infrastructure or centralized administrative node. The Proposed work aims at establishing a secure data transmission communication channel using threshold signature scheme. The proposed secure scheme organizes network into clusters using one hop distance and elects the most qualified and trustworthy node as cluster head. Keywords: - Mobile Adhoc networks, trust value, cluster, cluster head, certificate, threshold signature.
