The present application belongs to the technical field of information security and coding theory, and provides a minimal linear code construction method, a secret sharing method and a secret sharing system, comprising: first defining a trace function in a finite field, constructing a two-to-one mapping, a vector Boolean function with a finite discrete value of Walsh spectrum, and then defining a code word set based on the function, embedding the output of the trace function into a linear code generation expression to generate a minimal linear code with a weight set and a support without strict inclusion; then using the dual code to establish a one-to-one correspondence between the participants and the dual code coordinates, the minimal code word support and the minimum access structure, embed the secret generation share distribution, and the participants meeting the conditions restore the secret through linear combination. The system contains four functional modules, which are suitable for distributed storage, blockchain key management and other scenes, and realize safe, efficient and expandable secret sharing. The present application can improve the security, efficiency and flexibility of secret sharing, and is suitable for multiple scenes and easy to expand.

This application relates to a netlist processing method, electronic device, and storage medium for resistance calculation. The method includes the following steps: determining a first node and a second node in a first netlist; traversing a set of third nodes between the first and second nodes according to their connection relationship to determine the first order variable of each third node in the set, where the first order variable represents the minimum access order of the node; determining invalid resistors in the first netlist based on the first order variable of the third nodes; deleting invalid resistors and calculating the equivalent resistance between the first and second nodes to obtain a second netlist. This application, by analyzing the connection relationship between the first and second nodes, identifies and deletes invalid resistors in the netlist that have no impact on the calculation of equivalent resistance, reducing the size of the netlist and the computational load in the subsequent equivalent resistance calculation process, thereby improving computational efficiency while ensuring the accuracy of the equivalent resistance calculation.
