Security schemes of pairwise key establishment,which enable sensors to communicate with each other securely,play a fundamental role in research on security issue in wireless sensor networks.A general framework for key predistribution named H2(Hierarchical Hypercube) is presented,based on the idea of key distribution center and polynomial pool schemes.Theoretic analysis and experimental figures show that the new algorithm has better security performance and provides higher possibilities for sensors to establish pairwise key,compared with previous related works such as polynomial and polynomial pool-based pairwise key predistribution algorithms.
