Personal privacy has been realized as the most important security issue in wireless sensor networks. While there are much researches on privacy information protection, most of them shared the same condition that the sensing action happened anywhere at any time and few of them tackle the problem in the body sensor network (BSN). To address the problem, this paper proposes a system model according to BSN's specific features. The proposed model includes a hierarchical structure and an adversary model which originated from the traditional wireless sensor network. Based on the proposed model, an efficient green Secure Data Transmission Scheme is provided to protect users'privacy against the global eavesdropper. Next we conduct extensive simulations for proposed scheme by deploying it on the TinyOS, and compare it against a representative privacy-preserving scheme. The result shows that the scheme proposed in this paper has lower energy consumption and quicker response time, thus it fits for BSN more preferably.
