A New Unconditionally Secure Secret Key Agreement Model for Wireless Sensor Networks
Wang Qiu-hu · Chuangan jishu xuebao · 2014
To resolve the problems in the unconditionally secure secret key agreement model,a new model to obtain the initial random related information was proposed.The experiment results show that compared with existing models,the new model is equivalent in function to the source model and the channel model.However,in the new model,the bit error rate between legal communication parties remains unchanged,while the bit error rate of eavesdropper increases.Hence,the advantage of eavesdropper weakens and the total information key agreement rate increases.
