Optimization of key generation and update mechanism for pipeline calibration information of electric energy measurement equipment

In order to improve the confidentiality and anti attack ability of the verification information of the power metering equipment assembly line, reduce the risk of data leakage and tampering, an optimization method for the key generation and update mechanism of the verification information of the power metering equipment assembly line is proposed. Generate dynamic keys using multipath relative delay method; Revoke faulty nodes based on hash key chains and detect missing keys; Perform association repair on missing keys through key pair exchange method; Update the key through self-learning algorithms, optimize the anti attack performance of the encryption mechanism, and complete the optimization of the key generation and update mechanism for the pipeline calibration information of electric energy metering equipment. The test results show that after the application of the proposed method, the encryption throughput, key anti attack performance, and encrypted data integrity have all been significantly improved, enhancing the confidentiality and anti attack ability of the pipeline calibration information of electric energy metering equipment.
