An Broadcast Authentication Protocol Based on Linear Network Coding in Sensor Network
Atr Key · Journal of Computer Research and Development · 2010
Security of broadcast communication is one of the most challengeable issues in WSN.Linear network coding is a concise and efficiency data coding method,which could increase network throughput and improve network robustness.In order to improve the efficiency of broadcast authentication,a homomorphic network coding signature scheme is proposed based on the network coding mechanism and homomorphic signature technology.A broadcast authentication protocol for sensor networks is advanced with the proposed signature scheme.Analysis shows that the proposed protocol is secure and efficient.
