基于不对称密钥预分配和哈希函数，提出了一种新的移动异构传感器网络的密钥管理方案。该方案主要对网络不同子区域使用单独分开的密钥池，并为簇头节点从存储密钥池中选出密钥和为普通节点从存储密钥池中选出密钥的派生密钥，提高了现有方案的安全连通率和抗节点捕获攻击能力。同时，利用区域种子密钥和哈希函数实现了对移动簇头的认证，有效防止了伪造攻击。分析和仿真表明：该方案不仅能明显提高移动异构传感器网络的安全性能，而且能有效减少资源消耗。

This paper proposes a key management scheme for the mobile and heterogeneous wireless sensor networks based on the asymmetric key predistribution and hush functions .The scheme uses different separate key pools for different sub-regions in the sensor network ,assigns the cluster heads the keys selected from the corresponding separate key pools directly and offers the ordinary sensor nodes a few keys derived from the original keys selected from the same separate key pools .In these ways ,the proposed scheme can raise the security connectivity and the ability of resilience to the node capture attacks of the existing schemes .M eanw hile ,the mobile cluster heads can be authenticated by the other sensor nodes through the region seed keys and hush function to prevent fabricated attacks ef-fectively .Analysis and simulation show that the proposed scheme can not only improve the security of the sensor network significantly ,but also reduce the resources consumption greatly .
