Enabling data protection through PKI encryption in IoT m-Health devices

Ambient Assisted Living (AAL) aims at providing unobtrusive support to frail and elderly people for their daily life based on their context and situation. To this end, systems and services are required which are user-centric and adaptable towards the needs and capabilities of the people in need of care. The continuous integration of leading-edge technologies, such as cloud and wireless communication technologies, in the context of the Internet of the Things (IoT), can meet this requirement by enabling a new form of communication between frail and elderly people, their environment and relevant groups of care givers. However, for IoT-based systems to reach their full potential, sound answers need to be provided to the important security questions arisen, particularly those regarding authentication of entities (people and environmental objects) and data privacy. This paper presents a system based on Gateways (GW) that aggregate health sensor data and resolve security issues through digital certificates and PKI data encryption.
