To further enhance the security and connectivity for wireless sensor networks,proposed an improved key management scheme.introduced the scheme,a random key predistribution using multiple key spaces and multipath key reinforcement was based on group-based deployment model which in the paper of du wen-liang.analysis and simulations show that the scheme has lower memory and communication overheads, better ability against attacks besides good security performance.

为了进一步提高无线传感器网络的安全连通性，在分析du wen-liang等人的group-based节点投放模型的基础上，提出了一种改进的密钥管理方案：多密钥空间与多路径增强相结合的随机密钥预分配方案。结果分析表明，该方案需要较少的内存存储空间，不仅提高了系统的连通性，还降低了节点的被捕获概率。
