PP-NDNoT: On preserving privacy in IoT-based E-health systems over NDN

Internet of Things (IoT) is a novel networking paradigm that contributes greatly in improving daily life. However, it includes a great number of interactive nodes that generate, aggregate and exchange critical data. Thus, security and privacy challenges must be handled. Named Data Networking (NDN) represents a promising future networking paradigm fitting perfectly with the requirements of IoT applications and especially those related to security and privacy. In this paper, we leverage the basic feats of NDN vision for designing a robust privacy preserving NDN-based e-health IoT system (PP-NDNoT). It ensures security and fulfills content and contextual privacy requirements. Indeed, the security and privacy level is fixed according to the patient's state. To prove the robustness and effectiveness of our proposal, an extensive security analysis and performance evaluation are reported.
