Abstract

The fog-enabled healthcare IoT (F-HIoT) paradigm is impending for the prospective patient-healthcare applications. The fog nodes permit the smart medical wearables (SMW) to upload the information with low latency using 5G services. The security risks associated with the distributed attributes of fog nodes may hamper the monitoring of real-time medical reports with privacy. Many authenticated key exchange techniques can be witnessed to strengthen the interactions among SMW devices, fog nodes, and cloud server on insecure channels; however these are either based on computation-intensive crypto-primitives, or fail to provide anonymity to the F-HIoT end users. In this scheme, we propose an ultra-lightweight anonymous authentication protocol (FA-SMW) leveraging low cost crypto-primitive operations, i.e. Chebyshev chaotic map for setting up a mutually agreed session key among three entities. The security properties of FA-SMW are evaluated and analyzed under random oracle model and Canetti-Krawczyk (eCK) threat model. These findings suggest that the proposed protocol considerably meets the desired requirements in the fog-enabled F-HIoT system.
