Implementation method and data structure of nested traceable digital twinning body

Abstract

The invention discloses an implementation method and a data structure of a nested traceable digital twinning body. The implementation method includes: executing a signature step, an initial nesting step and a loop nesting step on the electronic data generated by each node; embedding the nested file of the previous node into the record file of the current node and carrying out signature verification to obtain a new nested file to obtain of a nested traceable digital twinning body, wherein the number of layers of the data structure corresponds to the number of nodes generating data, a data record file of each node comprises a data record file of a previous node and an electronic signature of the node, and the electronic signature of each node corresponds to a block structure in a block chain. The invention relates to a backtracking and source tracing technology, evolution information and evolution processing content of original data in the whole life cycle (from generation to propagationto extinction) are recorded, and after a data source is signed through a trusted timestamp and a KSI in the generation process, a nested docket data structure is used for recording the data to form aprocess of an electronic data traceable chain.

Description

technical field [0001] The present invention relates to the field of block chain technology, in particular to a method for realizing nested digital twins by using block chain technology. Background technique [0002] The basic model and technology of the Industrial Internet rely on the digital twin (Digital Twin). Although this concept originated in the military field, it was quickly recognized by leading industrial companies and invested a lot of resources in research. Digital twins are sometimes used to refer to the completion of a digital model of a factory building and production line before construction. In this way, the factory is simulated and simulated in the virtual cyberspace, and the real parameters are passed to the actual factory construction. After the workshop and production line are completed, they continue to exchange information in daily operation and maintenance. [0003] In the contemporary information technology facilities are being popularized at a ra...
