Edge-Computing-Based Scheme for Post-Quantum IoT Security for e-Health
Noman Nasir Minhas, Khwaja Mansoor · IEEE Internet of Things Journal · 2024
Internet of Things (IoT) devices are going to be a crucial data source in smart cities, often generating and communicating critical, sensitive, and private data that face threats of confidentiality breaches due to the rise of quantum computers. Even though NIST has approved post-quantum cryptography (PQC) schemes that promise to provide protection from quantum computer threats, these schemes can not be implemented efficiently on IoT devices, which often have computational and memory constraints. In this article, we propose an offloading scheme that uses post-quantum edge server (PQES) for the network that performs PQC-related computation and memory operations for IoT devices in the network. The proposed scheme reduces the computational, memory, and network load for IoT devices by manifolds and increases device performance while providing PQC security.
