INTEROPERABILITY MECHANISM OF TRUSTED DEVICES BASED ON BID

The interaction between traditional IoT devices generally requires a centralized cloud service for control and management, which inevitably causes problems such as low efficiency and high cost. In this paper, we study the possibility of interoperability of trusted devices through blockchain smart contracts and realize safe and low-cost connections between devices, by combining the characteristics of the new distributed BID, the decentralization of blockchain technology, and the difficulty of tampering. It is a technical verification of the BID, providing a reference for the in-depth study of subsequent interoperability and the further application of the BID.
