A cyber-physical system (CPS) introduces further topics for innovative discussions among medical practitioners, researchers, and industrialists. This extensive field integrates and provides in-depth collaboration of computation, communication, and control technologies. Medical CPS is a perceived term that evolved from health monitoring, which is obviously a subfield. Medical CPS, like other subfields of CPS, uses sensing technologies for reliable data acquisition and extensively depends on wireless sensor networks (WSN) for data transmission, storage, and control. This data is acquired through wearable or implantable medical devices, which are then used by a medical practitioner to diagnose and prescribe according to the health conditions of the patient. Therefore, it is considered as a substantial topic in the CPS domain. From the last two decades, data security has emerged as the primary concern for researchers due to the open-access wireless network in CPS. However, several key authentication schemes have been proposed as a possible solution that strengthens the data-protection types against vulnerabilities in the existing system. But due to rapid development in CPS-related technologies, new challenges have been evolving that created further considerations to test multiple design variations for key authentication schemes. This chapter covers detailed analysis of the authentication schemes and compares their efficiency in term of performance, storage, and computational requirements. Finally, it also highlights the pros and cons of each scheme of protection against available cyberattacks in medical CPS.
