The embodiment of the invention provides a trusted node determination method and device based on a blockchain network, and the method comprises the steps: enabling a first program on one node of the blockchain network to obtain the pass information of access equipment when equipment is connected to the blockchain network, and enabling the pass information to comprise the safety information of theaccess equipment; the first program calls the first contract object, and the first contract object generates security assessment information for the access device according to the pass information; and the node corresponding to the first program judges whether the access equipment is a trusted node or not according to the security evaluation information. In the embodiment of the invention, the safety information of the Internet of Things equipment is used as the selection condition of the trusted node of the networked blockchain network, and the overall safety of a consensus mechanism can be maintained or even improved on the premise of not losing the high performance of a weak centralized consensus algorithm.
Description
technical field [0001] The present application relates to the field of communication technology, in particular to a method for determining a trusted node based on a blockchain network and a device for determining a trusted node based on a blockchain network. Background technique [0002] With the development of IoT, traditional centralized IoT back-end services (for example, device management platform DMP, connection management platform CMP, data aggregation and analysis services) will be difficult to handle a large number of global IoT devices in the foreseeable future. Access management and data processing, the topology of the future Internet of Things will also develop from the current device-edge-cloud to cloud-edge-device + P2P distributed network. [0003] How to establish trusted connections, data interactions, and decentralized services in the Internet of Things of this scale and complexity is a real challenge. The blockchain provides a technical option that may sol...
