IoT Trust Management as an SIoT Enabler Overcoming Security Issues

Nowadays, security in the IoT world is a very popular area because it affects everyone's privacy and safety. The risk is increasing with Social IoT, involving intelligent devices interacting with each other dynamically and autonomously. However, while trying to limit interactions only to objects known as secure, we take the risk of service disruption. This means that traditional techniques are in general not applicable or inefficient in this context. In this paper, we present trust management as a promising paradigm that can deal with security concerns in IoT. We draw up various techniques and parameters implemented in this context and we describe the different challenges of managing SIoT trust.
