| 摘 要： | WSN自身特点决定了安全是对WSN研究中最为重要和最为基本的问题,尤其是密钥管理机制.本文在深入分析基于二元多项式的多维网格密钥预分配机制的基础上,对该方案进行了改进,保留其在内存需求方面较目前提出的其他方案都要小的优点,克服了不具备密钥更新功能,安全性不够理想的缺点.新的多维网格密钥预分配方案可以进行密钥更新,在只增加少量的内存需求的条件下大大提高了系统的安全性,更适用于WSN的实际应用.

| Abstract: | Security becomes the most important and basic aspect of WSN research because of WSN＇s own characteristics, especially the key management mechanism. The paper proposed an improvement of the Hypercube-based scheme based on dual-variate polynomials by deep analysis. The new scheme reserves the merit of less memory than other schemes and overcomes the drawback of lacking key update ability. The new Hypercube-based scheme can update key and improve the system security with little memory increase. It is more suitable for WSN＇s practical application. |
