A Digital Watermarking and Key Updating Based Defense Mechanism against Mobile Sink Replication Attack in Unattended Wireless Sensor Networks

YUAN Hong-xi;HU Rong-hua;CHEN Zhong-ju;School of Computer Science, The Yangtze University;  
In order to defend the attacker from the mobile Sink replication attack by capturing common nodes, stealing key information and gathering information collected by the network, a defense mechanism based on digital watermarking and key update was proposed. The key update mechanism can overcome the threshold defect in the key pool pre-distribution mode. Combined with digital watermarking technology, it can improve the security of key update and reduce the network traffic. Compared with the existing typical schemes, the authentication overhead is smaller and the threshold defect is overcome.
