文章提出了基于不规则区域的无线网络密钥管理方案,该方案根据不规则的网络形状把区域分成多个组,按照纵向和横向位置的关联组成具体的部署密钥池。在每个组内传感节点从部署密钥池中随机抽取密钥作为密钥环。文章通过性能分享,实验结果表明该方案解决了不规则区域密钥的管理问题。 In this paper, the wireless network key management scheme based on irregular region is proposed. The scheme divides the region into several groups according to the irregular network shape, and forms a specific deployment key pool according to the association of the vertical and horizontal positions. The sensor nodes in each group randomly select the key from the deployment key pool as the key ring. Through the performance sharing of the article, the experimental results show that this scheme solves the key area management problem in irregular areas.
