Security examination for linear network coding in wireless sensor networks
Qianbing Zheng · Engineering Journal of Wuhan University · 2010
As a new data coding method,the linear network coding can improve the data throughput of the wireless sensor networks(WSN);decrease the energy consumption of the node and reduce the data delay.But for the limitation of WSN,if we directly applying the existing linear network coding protocols to WSN,there will be some security threats.How to ensure the linear network coding protocols against danger in WSN has become the hot issue.Two parts of our research are described.Firstly we present the security problems that come forth when the linear network coding is applied to WSN.Secondly SEC,a security broadcast based on linear network coding in WSN,is presented.SEC can achieve the merit of the linear network coding and solve the security problems that are previously presented.
