A data privacy protective mechanism for wireless body area networks

As an important branch of wireless sensor networks, wireless body area networks (WBAN) has attracted widespread attention in various fields because of its portability and mobility. However, because much of the data collected by WBAN are related to personal information of the user, the sensitive private data may be at risk of leakage or malicious modification in the actual process of application and deployment. In order to assure the security and privacy of user's data in the environment of WBAN, this paper presents a Data Privacy Protective Mechanism for WBAN. In order to secure data and secure transmission, this mechanism combines symmetric key with an asymmetric key to transmit user's data. Then, it cuts and reorganizes the data in the process of transmission to better capture defense and the attacks of the nodes. Ultimately transmits the user's data securely under the condition that the data collected by the nodes are confidential and secure. Copyright © 2015 John Wiley & Sons, Ltd.     

Capacity Region of a Class of Gaussian Cognitive Degraded Broadcast Channel

This paper studies the cognitive broadcast channel in which the primary user com- municates to the primary receiver, while the secondary user has noncausal knowledge of the primary radio＇s codeword and expects to communicate to two secondary receivers. Comparing with the existing cognitive radio channel which considers only one secondary receiver, cognitive broadcast channel studies the case that there are multiple secondary receivers. To this end, we investigate the fundamental limits of the performance of the Gaussian cognitive broadcast channel from the information theoretic perspective. Specifically, we derive the capacity region of the Gaussian cognitive degraded broadcast channel with weak interference.
