Abstract: According to the characteristics of Wireless Sensor Networks(WSN) and the defects in current key management schemes, a key management scheme(KMSBDK) based on deployment knowledge is presented using Identity-Based Cryptography(IBC). The scheme is analyzed from security, key connectivity, scalability and efficiency. Compared with some current popular schemes, KMSBDK achieves better performance.

摘要： 在充分考虑无线传感器网络自身特点的基础上，针对现有无线传感器网络密钥管理中存在的问题，利用基于身份的加密算法，提出一个基于部署信息的无线传感器网络密钥管理方案(KMSBDK)。从该方案的安全性、连通性、可扩展性、有效性等方面进行分析，并与现有一些典型方案进行比较。结果表明，KMSBDK有较好的性能。
