A Novel Key Distribution Algorithm in Wireless Sensor Network

摘要

This paper studies the E-G key pre-distribution algorithm principle, and a new key distribution algorithm based on the Blom key pre-distribution model is proposed. The nodes is deployed in a hexagonal area. Each cluster uses preshared key to establish key pair, Blom key pre-distribution model is used in the establishment of key pair among clusters. The new algorithm is superior to E-G algorithm, and close to the PIK algorithm proposed by CHAN in security. and its connectivity is better than E-G algorithm and PIK algorithm.
