Enhancement of the security of RBS for wireless sensor networks

Time synchronization is one of the fundamental techniques for the wireless sensor networks to obtain the real-time effective information. The security of this technology is becoming increasingly important. In this paper, we analyze the security of RBS, the synchronization algorithm in WSN, point out the potential vulnerabilities existing in the algorithm, and propose optimization on security for the algorithm. Simulation result shows improved algorithm not only defends external attacks effectively, but greatly reduces the effects of internal attack.
