The Internet of Things (IoT) has converged with cloud computing to provide comprehensive services to users in different locations. However, with the exponential growth of smart devices connected to the internet, cloud computing presents major challenges, especially for applications that require low-latency real-time processing. Therefore, the fog computing paradigm has emerged, which is more compatible with IoT, where events are processed close to where they occurred to get a convenient and fast response time. Authentication is a critical issue for fog computing security, as fog gateways and IoT devices face many attacks. The main problem with authentication between IoT devices is that they have limited compute resources and processing. On the one hand, certificate-based authentication algorithms are secure, but they are difficult for IoT devices. On the other hand, pre-shared authentication algorithms such as PSK are suitable for device-poor devices, but are not widely used due to their low security. Therefore, this document proposes to use the ECDHE (Elliptic Curve DiffieâHellman Ephemeral) key exchange algorithm with the pre-shared key (PSK) as a lightweight and secure authentication scheme between the fog gateway and the IoT device, based on the Message Queuing Telemetry Transport (MQTT) publish-subscribe protocol in a distributed fog computing architecture. The proposed ECDHE-PSK authentication scheme uses an ephemeral pre-shared key instead of heavy certificates, which is very lightweight and also provides a PFS (Perfect Forward Secrecy) function to improve security compared to the static PSK algorithm. To assess the resource consumption and security resistance of the proposed schema, it was implemented in the real-world test environment and then compared to two state-of-the-art certificate-based authentication schemes and a static PSK-based schema. Comprehensive performance and security assessments have shown that in the distributed fog computing architecture for publications, the proposed ECDHE-PSK is almost as light as the PSK algorithm, while having all the security features of certificate-based algorithms.
