摘　　要：随着时间的推移,传感器网络中正常工作的节点越来越少。为了确保网络正常工作,必须适时地添加新节点。针对传感器网络,提出了一个高效的密钥建立方案。该方案构造了n个相互独立的子密钥池,两相邻子密钥池之间存在联系密钥。第j次部署的传感器节点只从第j个子密钥池中选取密钥。理论分析及模拟结果表明与使用固定密钥池的方案相比,该方案的抗毁性显著提高。In sensor networks, the number of nodes that can work well decreases with time. To keep networks working, it is nece- ssary to timely add new nodes to networks. For sensor networks, an efficient key establishment scheme is proposed. In the scheme, n disjointed sub-key pools are constructed, and there are association keys between two adjacent sub-key pools. Nodes deployed in the jth time are preloaded with keys only chosen from the jth sub-key pool. The theoretical analysis and numerical experiment show that the proposed scheme can provide stronger resilience against node capture compared with the existing schemes that use fixed key pools.
