Securing Edge Services for Future Smart Healthcare and Industrial IoT Applications

Secure and intelligent environments are crucial for fostering future IoT applications such as digital healthcare and Industry 4.0. Such smart environments must enable needed digital services to the respective users ubiquitously and fulfill critical requirements such as ensuring security, privacy, and low latency. This paper summarizes the dissertation work [1] through three major contributions, i) a lightweight biometrics-based user authentication mechanism in the smart and gadget-less healthcare environment, ii) a conceptual three-tier mechanism for secure nodes bootstrapping and secure users access for digital services, and iii) a Blockchain and Edge computing based network architecture for IIoT use case to fulfill the needed requirements such as low-latency, trust management, and security among others. The performance evaluation of the proposed framework is carried out, and the obtained results highlight valuable insight of this work for enabling a secure future hyperconnected environment for various applications.
