The Internet of Things for healthcare monitoring: Security review and proposed solution

Abstract

The development of the Internet of Things will greatly facilitate the process of patient's diagnosis and monitoring, with small IP-based wireless sensors implemented on the patient's body, his physiological parameters, such as blood pressure and heart rate, can be monitored remotely and continuously. This scenario must absolutely respect the confidentiality and privacy of patient's medical information, only caregivers and authorized persons should possess the right to access these information. The security must be ensured throughout the healthcare application scenario. This paper presents a study of the potential security problems in this application, and proposes a security model as a solution. Our model is based on symmetric cryptography with a proposed key management system and network nodes authentication mechanism.
