Security Issue for Wireless Sensor Network

Abstract

newline Sensor networks have great potential to be employed in mission critical situations like battlefields but also in more everyday security and commercial applications such as building and traffic surveillance, habitat monitoring and smart homes etc. However wireless sensor networks pose unique security challenges. While the deployment of sensor nodes in an unattended environment makes the networks vulnerable to a variety of potential attacks, the inherent power and memory limitations of sensor nodes makes conventional security solutions unfeasible. Though there has been some development in the field of sensor network security, the solutions presented thus far address only some of security problems faced. This research presents four security scheme WSNSS Wireless Sensor Networks Security Scheme to provide a comprehensive security solution against the known and unknown attacks in sensor networks. The proposed framework consists of five scheme: 1 PairWise key establishment using Random Number and Distinct Random Functions in WSNs scheme 2 A Routing BMU Algorithm through smart role of Intermediate Nodes in WSNs 3 Broadcast Tree Authentication Protocol using Pairwise Keys in WSN 4 Secure Authentication Approach Using Diffie Hellman Key Exchange Algorithm for WSN and 5 Secure Authentication Diffie Hellman key Exchange algorithm to Construct the Information Potential and Secure in Field WSNs. However when deployed as a framework a high degree of security is achievable. WSNSS takes into consideration the communication and computation limitations of sensor networks. While there is always a trade off between security and performance experimental results prove that the proposed framework can achieve high degree of security with negligible overheads. A base station frequently broadcasts messages such as network query time synchronization multi-hop routing. The basic problem in such communication is source authentication because receivers are not trustable and are unreliable communication environment. Therefore a
