Abstract: Key pre-distribution management scheme should do the best to reduce the message pre-storage in sinks under the premise：high security，strong key agreement，less communication，less computation complexity.Key pre-distribution management scheme based on secret message is in order to solve this problem.In this scheme，sensor generates the safe session key with its near sensors only need communicate with the base station once.So it is suitable for the abundance of sensors network.After comparative analysis，this scheme has advantages in security，key agreement，communication compare to the q-composite scheme.

Key words: key pre-distribution, little communication, little memory, secret message

摘要： 密钥预分配算法的目标是在保证安全性、密钥连通性、通信量、计算复杂度等性能的前提下，尽量减少预先存储的信息量。文章针对该目标提出了一个基于秘密信息的无线传感器网络密钥预分配方案。方案中节点只须和基站进行一次交互就可以和所有邻居节点形成安全的会话密钥，适合节点数量庞大的网络。通过比较分析，该方案与q-composite等其他方案相比在安全性，密钥连通性，通信量方面都有一定的优势。
