Security Broadcast Based on Linear Network Coding in WSN
Zhengjian Zhu, Qingping Tan, Peidong Zhu, Qianbing Zheng · 2008
The broadcast is the important communication mode. As a new data coding method, the linear network coding can improve the data throughput of the broadcast, decrease the energy consumption of the node and reduce the data delay. How to combine the linear network coding with the broadcast in WSN in security has become the hot issue. In the paper, we introduce two parts of our research. Firstly we present the security threats that come forth when the linear network coding is applied to WSN. Secondly, SBLNC, a security broadcast based on linear network coding in WSN, is presented. SBLNC can achieve the merit of the linear network coding and solve the security problems that are previously presented.
