Abstract

The invention discloses a fault-tolerant ciphertext data aggregation method based on a smart engineering construction system platform, comprising: setting public parameters in the engineering construction information management center, and assigning fault-tolerant parameters and secret parameters to the smart engineering construction system platform; During the design period, the end user of the engineering construction will homomorphically encrypt the sensitive data to obtain the homomorphic ciphertext, and upload the homomorphic ciphertext to the smart engineering construction system platform; the smart engineering construction system platform setting has successfully uploaded the engineering construction of the homomorphic ciphertext The set of end user identities, calculate the Lagrangian interpolation coefficient according to the serial number corresponding to the engineering construction end user identity that has successfully uploaded the homomorphic ciphertext; calculate the aggregated ciphertext, and use the secret parameter to decrypt the aggregated value of the sensitive data; calculate the sensitive Average state value of the data. The method of the invention can grasp the average state value of the sensitive data, which facilitates timely adjustment of engineering construction parameters by the intelligent engineering construction system platform.

Description

technical field [0001] The invention relates to the technical field of engineering construction informatization, in particular to a fault-tolerant ciphertext data aggregation method based on a smart engineering construction system platform. Background technique [0002] Due to the complexity of engineering construction management, the dynamic changes of the construction site and the multi-source transportation of raw materials, the traditional engineering construction system management urgently needs to be upgraded, and it is impossible to achieve refined management. In particular, in the traditional engineering construction system, the reporting and summarization of traditional business process data has poor timeliness, lack of data correlation, and failed to form a unified project supervision system; construction site management is not standardized, data is not rigorous, and construction site safety management is not in place. , lacks the ability to backtrack to the proble...
