An Enhanced Authentication Mechanism to Secure Re-programming in WSN

Wireless reprogramming in (WSN) is the process of inseminating new code or correlated commands to sensor nodes. It enables sensor nodes to self-reprogram so adapting them to unravelling milieu.WSN Applications include geophysical/habitat monitoring, controlling disaster, battlefield information, collection and monitoring, security surveillance and home entry systems. WSN poses security challenges including forgery of sensor data, eavesdropping, DOS attacks, and compromise of sensor nodes. Hence, to avoid pernicious nodes from joining the sensor network, immense security is required in network protocols .The secure and distributed reprogramming protocol is inherent to impersonization and altered/spoofed information attack by which an adversary can impersonate any privileged user to perform re-programming. The main purpose of this study is to implement new re-programming protocol that is more secure and faster while maintaining all the major functions of re-programming such as version control, scope selection, encoding/decoding, code dissemination. When deployed as a framework, high degree of security, better computation and communication performance is reachable compared with the conventional network security solutions.
