Distributed Trust-Based Monitoring Approach for Fog/Cloud Networks

Abstract

The fog computing paradigm presents an extension of the cloud computing in order to more ensure the requirements of Internet of things (IoT). Hence, the growth of fog-IoT system and their openness to their socioeconomic environment has led to new needs in terms of security. There are many damages resulting from security breaches and violations. In order to address these challenges, this article proposes a novel framework to further enhance the data security and privacy and the system performance, for the IoT users trying to connect to fog network. In fact, a trust-based monitoring strategy is suggested to avoid system’s damages and attacks, and also to maintain low latency, because it is easier to avoid damage resulting from security breaches than to wait for a violation and to try to restore and repair the damage caused. The findings of our evaluation indicate that the proposed monitoring process is an efficient solution for system supervision, and detection and prevention attacks, with a fast processing time.
