An Improved Random Key Predistribution Scheme in Wireless Sensor Network

Based on the analysis of the existing Random Key Predistribution(RKP)schemes in wireless sensor network,a hash random key predistribution scheme H-RKP is proposed by introducing multi-path reinforcement scheme,q-composition scheme and one-way cryptographic hash function based random key predistribution algorithm.The security performance of the scheme under node capture attack is analized.The H- RKP scheme can further improve the security of the existing RKP schemes.
