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

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.
