ABSTRACT
An e-health system delivers health care services to its users (physicians, nurses, pharmacists, and patients) with the secure use of information and communication technologies. An e-health system provides a substantial ability to upgrade the quality of on-demand health care, reliability, diagnosis, bring down medical costs, and meet the challenges posed by an aging society. The collection of lightweight, low-power-usage wireless sensor nodes used in the medical field are known as biomedical smart devices. These smart devices are implanted within or outside the human body to remotely measure the real-time parameters of patients’ physiology and activity. The biggest challenge that an e-health system faces is the privacy and security of data. Data requires securing at different layers. Data privacy can be defined as data accessible only to authorized users. To protect security, various security protocols have been proposed: an energy-efficient routing Protocol, a secure protocol for user authentication and key agreement, a node-to-node authentication protocol that eliminates the man-in-the-middle attack, a lightweight anonymous authentication protocol for network security, and a trust key management protocol for biomedical smart devices. In this chapter, we discuss security protocols for biomedical smart devices.
