Abstract

The invention discloses a fault-tolerant ciphertext data aggregation method based on an intelligent engineering construction system platform, and the method comprises the steps: an engineering construction informatization management center sets public parameters, and distributes fault-tolerant parameters and secret parameters for the intelligent engineering construction system platform; in a preset period, the engineering construction terminal user performs homomorphic encryption on the sensitive data to obtain a homomorphic ciphertext, and uploads the homomorphic ciphertext to the intelligent engineering construction system platform; the intelligent engineering construction system platform sets a set of the user identities of the engineering construction terminals which have successfully uploaded the homomorphic ciphertexts, and calculates a Lagrange interpolation coefficient according to the serial numbers corresponding to the user identities of the engineering construction terminals which have successfully uploaded the homomorphic ciphertexts; calculating an aggregation ciphertext, and decrypting by using a secret parameter to obtain an aggregation value of the sensitive data; and calculating an average state value of the sensitive data. According to the method, the average state value of the sensitive data can be mastered, and an intelligent engineering construction system platform can conveniently adjust engineering construction parameters in time.

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 management of traditional engineering construction systems urgently needs to be upgraded, and it is no longer possible to achieve refined management. In particular, in the traditional engineering construction system, the reporting and summarization of traditional business process data is poor in timeliness, lacks data association, and fails to form a unified project supervision system; the construction site management is not standardized, the data is not rigorous, and the safety management of the construction site is not in place , lack of retrosp...
