Blockchain-Enabled Trust Management in Service-Oriented Internet of Things: Opportunities and Challenges

Abstract

With the development of information and computer technology, internet of things (IoT) technology has brought tremendous changes to people's production and life. The emergence of IoT creates new opportunities to stimulate innovative services that better converge the information resources of IoT objects. However, due to the increasing scale of the network and the intelligence of devices, the development of the service-oriented IoT has also been accompanied by the issue of trust which is crucial to the security and stability of the system. Blockchain, as an emerging distributed ledger technology, is considered to be a driving force to improve the trust management of the service-oriented IoT. This research is a systematic analysis with the goal of illustrating and analyzing how the blockchain contributes to addressing the issue of trust management in service-oriented IoT. The objective of this paper is to understand the trust issue in the service-oriented IoT and analyze the potential blockchain-based solution, thereby motivating further research interest in this field.
