Pairwise Key Predistribution Algorithm Based on Hierarchical Hypercube Model

通过所建立对偶密钥,传感器网络节点之间可使用加密技术进行通信,从而保障了通信的安全性。在KDC和基于多项式池的密钥预置模型基础上,提出了一种用于密钥预置的层次超立方体模型及其密钥预置算法。理论与实验分析表明,与基于多项式和基于多项式池的对偶密钥预置算法相比,该算法具有更好的安全性能与更高的对偶密钥建立概率。

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.
