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, the authors 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.
