Assured Full Communication by Merging Blocksrandomly in Wireless Sensor Networks Usingreed Solomon Code for Key Predistribution

Limited resources available to the sensors (nodes) constituting a Wireless Sensor Network (WSN) is major constraint while dealing with security of such networks. This restrict one to use symmetric key cryptography instead of public-key techniques for transmission of message amongst the nodes. In any symmetric key system, both the sender and receiver must possess the unique enciphering and deciphering key prior to exchange of message. This leads to key distribution in the sensors which in itself is a major challenge. Though there are several methods of distributing the keys, due to resource constraints, Key Pre-Distrubution (KPD) is preferred over other techniques.
