Wireless Body Area Networks (WBANs) is an evolving technology for healthcare applications. It provides the opportunity to medical service providers to remotely monitor the health status of their patients on real time basis. In WBANs, sensor nodes collect data of vital signs and send to the medical server for further analysis. Since this data contains life-critical sensitive information so the security, privacy and safety of this data is a main challenge. In this paper, we highlight the major issues and challenges related to data security and privacy in WBANs. Further, we propose a data hybrid method named D-Sign for encrypting and decrypting using digital signatures. We also analyze the performance of the proposed method against the state-of-the-art mechanisms aimed to ensure the security and privacy in WBANs.
