Dynamic Nonlinear Key Distribution in Wireless Sensor Networks
Shu Renyi · Journal of Yanbian University · 2011
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.
