Project scoring system based on digital signature

Abstract

The invention relates to the technical field of project scoring data security, and discloses a digital signature-based project scoring system, which comprises the following steps of: before a project completion person PCi, a project reviewer PRi and a project acceptance person PAi request to carry out data interaction with project scoring system server software running on a cloud computing server CCSpss, the project completion person PCi performs signature processing on the information M1 to obtain a signature S1 of the information M1; the project reviewer PRi firstly verifies the signature S1 of the information M1 of the project completion person PCi, and then performs signature processing on the information M2 to obtain a signature S2 of the information M2; the project acceptance person PAi firstly verifies the signature S2 of the information M2 of the project reviewer PRi, and then performs signature processing on the information M3 to obtain a signature S3 of the information M3; and then a system administrator SAccs on the cloud computing server CCSpss verifies the signature S3 of the project acceptance person PAi. According to the invention, the technical problem of how to overcome the forgery and tampering of the project review data in the network transmission process is solved.

Description

technical field [0001] The invention relates to the technical field of project scoring data security, in particular to a digital signature-based project scoring system. Background technique [0002] The project scoring system is usually used in the project acceptance process. The traditional operation method is: the project completion team introduces the project on site, and displays the project completion status and all project acceptance materials. The project reviewers score the project according to their own judgment on site. Then the staff will enter the scores scored by the reviewers into the system, and calculate the review results according to the review rules, then print out the scoring results and comments, and finally classify and archive the projects according to the acceptance results. The entire project review process needs to be completed by all reviewers at the review site. The review results need to be entered and calculated manually, which is prone to error...
