Abstract
Internet of Things (IoT) is an emerging networking paradigm that aims to improve human daily life. It includes a huge number of interactive nodes that generate, aggregate and exchange sensitive data. Thus, security and privacy challenges must be addressed. Various studies on privacy in the area of IoT were proposed. However, none has considered all privacy requirements. To meet such requirements, we propose a novel privacy-preserving IoT-based e-health solution. This solution satisfies content and contextual privacy requirements. It is based on a specific communication scenario and a novel identity-based encryption scheme, respecting the limited resource nature of smart-things. To validate our proposal, an extensive security analysis is provided. Its effectiveness is also demonstrated through a performance evaluation.
