    Technological advances in biomedical engineering have significantly improved the quality of life and increased the life expectancy of many people. In recent years, there has been increased interest inwireless body area networks(WBANs)research with the goal of satisfying the demand for innovative biomedical technologies and improved healthcare quality [1, 2]. One component ofsuch advanced technologiesisrepresented bythe devicessuch aswirelessin vivo sensors and actuators, e.g., pacemakers, internal drug delivery devices, nerve stimulators, wireless capsule endoscopes (WCEs), etc. In vivo wireless medical devices and their associated technologies represent the next stage of this evolution and offer a cost efficient and scalable solution along with the integration of wearable devices. In vivo-WBAN devices (Figure 7.1) are capable of providing continuous health monitoring and reducing the invasiveness of surgeries. Furthermore, patient information can be collected over a larger period of time, and physicians are able to perform more reliable analysis by exploiting big data [3] rather than relying on the data recorded in short hospital visits.

    Physical layer security for wireless implantable medical devices
    (Institute of Electrical and Electronics Engineers, 2015) Ankaralı, Zekeriyya Esat; Demir, Fatih; Qaraqe, Marwa; Abbasi, Qammer Hussain; Serpedin, Erchin; Arslan, Hüseyin; Gitlin, Richard
    Wireless communications are increasingly important in health-care applications, particularly in those that use implantable medical devices (IMDs). Such systems have many advantages in providing remote healthcare in terms of monitoring, treatment and prediction for critical cases. However, the existence of malicious adversaries, referred to as nodes, which attempt to control implanted devices, constitutes a critical risk for patients. Such adversaries may perform dangerous attacks by sending malicious commands to the IMD, and any weakness in the device authentication mechanism may result in serious problems including death. In this paper we present a physical layer (PHY) authentication technique for IMDs that does not use existing methods of cryptology. In addition to ensuring authentication, the proposed technique also provides advantages in terms of decreasing processing complexity of IMDs and enhances overall communications performance.
