CAD signature certification system used for construction drawing examination and CAD signature certification method used for construction drawing examination

Abstract

The invention discloses a CAD signature certification system used for construction drawing examination. An examination system host is connected with the input end of a CA signature server through the Internet, an Internet router and a firewall. The output end of the CA signature server is connected with the CAD signature application server and a PDF signature application server. The invention further discloses a CAD signature certification method used for construction drawing examination. The method comprises the steps of 1 logging in the CAD signature certification system through a login password; 2 waiting for a CA certificate authority to issue a CA certificate; 3 ensuring that a CAD drawing is marked with a signature identifier; 4 confirming each professional CAD drawing; 5 calling the key and signature of the CA signature server to carry out electronic signature on the drawing; 6 verifying the CA signed CAD drawing through drawing experts; 7 carrying out CA qualified signature again according to screening; and 8 downloading the drawing by a design organization. The validity of the CA qualified signature is verified through a signature plug-in.

Description

technical field [0001] The invention relates to a CAD signature authentication system and a CAD signature authentication method for reviewing construction drawings. Background technique [0002] The current construction drawing review process uses paper drawings to sign and seal, so that online batch signing of construction drawings is not possible, which not only wastes energy and space for piling up materials, but sometimes paper drawings cannot be seen clearly when annotating, which affects the approval The efficiency is relatively low, and it is prone to leakage and tampering. Contents of the invention [0003] The invention provides a CAD signature authentication system and a CAD signature authentication method for reviewing construction drawings, which not only can prevent tampering and leaking secrets, but also realize paperless drawing review and ensure the integrity and safety of CAD drawings . [0004] The present invention adopts the following technical soluti...
