A secure data transmission scheme based on information hiding in wireless sensor networks

Abstract

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 infor-mation of a sensor node. Secondly, sensitive information is uniformly and randomly embed-ded into the ordinary data by using the space-efficient randomized data structure characteris-tic of Bloom Filter. Experimental results and performance analysis demonstrate that the pro-posed scheme can efficiently detect the malicious node with fake identities through the sensi-tive information. On the other hand, our scheme can protect the sensitive information without affecting the transmission and usability of the ordinary data.
