Access Service Records Based Trust Management Scheme for Internet of Things
Xuefei Li, Ru Li

TL;DR
This paper introduces TokenChain, a trust management scheme for IoT that uses a unified data structure and encryption to enhance security, traceability, and cross-scenario trust evaluation in a distributed IoT environment.
Contribution
It proposes TokenChain and TBTM, a novel three-tier trust management architecture that improves security, traceability, and cross-scenario trust interaction for IoT systems.
Findings
TBTM achieves high security and performance in complex scenarios.
It supports cross-scenario interaction and two-way trust management.
TBTM demonstrates resistance to malicious attacks and effective trust evaluation.
Abstract
The distributed structure of the Internet of things has gradually replaced the centralized structure because of its scalability, security, and single point of failure. The huge scale of information recording of the Internet of things brings challenges and opportunities to the trust management of the Internet of things. Through the analysis of a variety of existing trust management schemes, this paper proposes a unified data structure for distributed access service records, TokenChain, in which triple DES data encryption is used to ensure privacy and traceability, to achieve a unified trust management scheme. Based on TokenChain, a three-tier trust management architecture (TokenChain-Based Trust Management, TBTM) is implemented in the data layer, computing layer, and control layer. Trust evaluation is affected by four statistics and finally converges to a real value under certain…
