Abstract
Widely used Internet of Things (IoT) has led to close cooperation between electronic devices. It requires strong reliability and trustworthiness of the devices involved in the communication. However, current trust mechanisms have the following issues: (1) Heavily relying on a trusted third party, which may incur severe security issues if it is corrupted. (2) Malicious evaluations on the involved devices may bias the trustrank of the devices. By introducing the concept of risk management into the trust mechanism, we propose a trust mechanism for distributed IoT devices in this paper. In the proposed trust mechanism, trustrank is quantified by normative trust and risk measures. Performance analysis shows that the proposed trust mechanism has a higher probability of high trust device being selected and higher success rate of cooperation.
