| 摘 要： | 针对密钥管理与路由信息脱离的现象，提出一种基于按需路由协议的多项式密钥预分配改进方案。该方案利用网络路由的拓扑信息和基站功能，使基站集中存储重要安全信息并承担大量计算负荷，普通节点仅保存其邻居的多项式份额。该机制能有效防止密钥泄漏，增强网络的安全性，节省节点的能量资源。

| Abstract: | To solve the limitation of combination between traditional key management and routing information, this paper presents an improved scheme of polynomial key pre-distribution based on on-demand routing protocol according to the security requirement.The scheme makes full use of the topology information of routing and the function of the base station, which gathers the important security information and the computing loads, to insure the sensor only stores the polynomial quantum of neighbors.The mechanism can e... |
