为减少无线传感器网络中大量的共享密钥,提出了计算每个通信数据包的动态分配密钥.该方法为：通过种子密钥加密分配密钥,由分配密钥计算数据密钥,由数据密钥加密数据,并在通信包中将分配密钥的密文与机密数据一起传输;接收节点获得数据包后,分析出包计数、节点身份标识、包跳段、分配密钥的密文和数据密文,再由共享的种子解密动态分配的分配密钥.结果表明,用于无线传感器网络的动态非线性分配密钥的方法可实现无线传感器网络共享少量种子密钥和机密通信.

In order to decrease the amount of the shared confidential key between nodes,the dynamic nonlinear distribution key for every package in wireless sensor networks was proposed.In the method,the seed key was used to encrypt distribution key,the data key was come from the distribution key,and the data was encrypted with the data key,the cipher text of the distribution key and the cipher text of data were transmitted in one communication package.When the receiver node received the package,it analyzed the package to get package count,node identifier,package hops,cipher text of distribution key,and cipher text of data.The cipher text of the distribution key was decrypted with the shared seed key.The conclusion is that the dynamic distribution algorithm in wireless sensor networks can realize confidential communication through dynamic nonlinear key distribution in wireless sensor networks with sharing a few seed keys.
