摘　　要：随着无线传感器网络(WSN)的广泛应用,其安全问题尤其突出,WSN的密钥分配和管理受到越来越多研究者的重视。通过收集节点的部署信息对区域进行划分,提出一种根据指纹识别进行模式匹配的密钥预分配方案。该方案将网络划分成多个较小区域,同时将密钥种子池分成多个与其对应的子密钥种子池。节点通过挑选相应区域内种子生成模式和文本,根据匹配成功时生成的指纹函数值建立通信密钥。安全性分析结果表明,与传统的随机密钥预分配方案相比,该方案具有较高的网络连通率及较低的存储能耗。With the widely application of the Wireless Sensor Network（WSN）,the security problem is more and more prominent. The distribution and management of WSN receive more and more attention. This paper proposes a key predistribution scheme which matches patterns according to the fingerprint identification by dividing the network after collecting the deployment information. The scheme divides the network into several domains,and the seed pool is divided into multiple sub-seed pools relatively. Nodes select seeds from relative areas to generate patterns and texts,and use fingerprint function values as communication keys when match successfully. The performance and security analysis shows that the scheme can substantially improve a network＇s connectivity and reduce storage consumption compared with the traditional random key pre-distribution scheme.
