Wireless sensor networks hold the promise of facilitating large-scale and real-time data processing in complex environments, therefore the security is a critical issue that must be resolved.In order to prevent attacks by adversaries with fake identities, we propose a secure data transmission scheme based on information hiding technique.Firstly, one superficial change made to the beacon message of original CTP is to mark the unique identity information of a sensor node.Secondly, sensitive information is uniformly and randomly embedded into the ordinary data by using the space-efficient randomized data structure characteristic of Bloom Filter.Experimental results and performance analysis demonstrate that the proposed scheme can efficiently detect the malicious node with fake identities through the sensitive information.On the other hand, our scheme can protect the sensitive information without affecting the transmission and usability of the ordinary data.
