Security, Privacy, and Trustworthiness in Medical Cyber Physical Systems

Medical Cyber Physical Systems (MCPS) are life-critical, context-aware, and networked systems of medical devices that provide tight integration of and coordination between the cyber world of computing and communications and the physical world. Recent advances in mobile and wearable healthcare, communication, and Cloud computing technologies are making MCPS a promising platform for scientific advancement and development of new tools that may improve patients’ health and wellbeing. Coming along with the potential social economic and personal healthcare benefits are significant security, privacy, and trustworthiness challenges in MCPS, due to unreliable embedded software controlling medical devices, weak computing and networking capabilities of medical devices, and adaptive privacy requirements introduced by complicated physiological dynamics of patient bodies. In this talk, I will present two works about how to secure the communication for mobile and wearable healthcare devices. In the first work, we consider most wearable devices are extremely limited in their capability to display information due to their small size. I will present a new LightTouch method by which a wearable device can establish a secure connection to an ambient display, such as a television or computer monitor, based on the user’s intention to connect to the display. We built a wearable prototype and carried out extensive experiments using multiple displays to demonstrate the effectiveness and security of the LightTouch. In the second work, we studied the wireless body area network (WBAN), which is composed of multiple wearable devices on the same human body. Different from other traditional networks, WBAN has many constraints in communication and...
