Abstract

The invention belongs to the technical field of block chains and the technical field of Internet of Things, and relates to an Internet-of-Things data management method based on block chains and edge computing. The method has the advantages that firstly, an efficient, safe and low-consumption layered mass Internet-of-Things data collection and aggregation mechanism is designed based on the advantages of Internet-of-Things network architecture and edge computing; secondly, complete data is stored outside the chain, the block chain storage pressure is relieved, and the performance is improved; an index hash value is stored in the block chain, so that a credible, safe and traceable data storage method is ensured; and finally, the credible data sharing method is provided, and auditing, credibility and traceability of a data sharing process are ensured based on an intelligent contract technology of a block chain.

Description

technical field [0001] The invention belongs to the technical field of blockchain and the technical field of the Internet of Things, and specifically relates to a data management method of the Internet of Things based on blockchain and edge computing. Background technique [0002] With the vigorous development of Internet of Things technology, large-scale wireless sensor networks controlled by different owners are increasing and collecting massive and valuable Internet of Things data. However, the computing and storage resources of sensors are limited and large-scale, and the collection and processing of IoT data involves multiple layers in the network; in addition, different data owners do not want to expose their private data, which also makes data sharing and multi-party There is a crisis of trust in collaboration. [0003] At present, for data collection tasks across multiple layers of the network, it is necessary to consider efficiency and privacy protection issues. T...
