中文摘要：

随着无线传感器网络的广泛应用，其安全性也越来越受到人们的关注。但是，由于节点自身的能源、计算能力、存储能力的限制，传统的密钥分发技术如密钥分发中心（KDC）等不适合无线传感器网络的应用。在简要介绍适合无线传感器网络的密钥分发方案的同时，也对每种方案的优缺点作出简单的评价。

英文摘要：

Advances in technology introduce new application areas for sensor networks, and the security issue has been brought forward meanwhile. The traditional cryptography such as RSA is not suitable for the wireless sensor networks due to the characteristic of the nodes. Not only introduce some typical key distribution schemes, but also do evaluation to every scheme in this paper.
