摘　　要：在讨论无线传感器网络的安全需求、深入分析无线传感器网络密钥管理的特点以及评价指标的基础上,介绍了当前的两类密钥管理机制:基于KDC的机制和基于密钥预分发的机制.并通过分析现有的随机密钥预分发方案,对它们的连通性、抗节点俘获能力和支持的网络规模作了详细的分析和比较,指出各自的优缺点以及适用的场合.Based on discussing the security demand of WSN, and analyzing the challenges to the key management scheme in the WSN and describing the metrics of it, it introduced two kinds of key management models for WSN. One based on the key distribution center （KDC） and the other based on key pre-distribution. By analyzing and comparing the previously-proposed random key pre- distribution schemes in terms of the connectivity, resilience against node capture and the max network size, it indicate their merits, weaknesses and the suitable scenarios.
