In order to achieve the second object of the present invention, the present invention adopts the following technical scheme:
The design method using the paperless design system comprises the following steps:
s1, a client 1 acquires a research and development file index of a research and development project;
S2, the client 1 selects an item to be edited in the research and development file index, and invokes a configuration template and design software information corresponding to the item;

s65, the automatic signature module 25 completes the signature, and the signed file is returned to the original position and the signature result is returned.
The trusted signature implementation principle in the present disclosure is:
(1) The document to be signed by the trusted signature first becomes a byte stream;
(2) The entire PDF file is written to disk, storing the signature value is an array ByteRange of four digits. The array comprises: the actual signature value of the signature coordinates (offset of the file, signature value field length (content requiring hash) is stored in the "/Contents key" between the end of the first sequence and the beginning of the second sequence of the array;
(3) The offset (coordinates of the signature) in the file is obtained based on the signature position selected during the signing process and the correct signature value is used to overwrite ByteRange arrays. Because the signature position cannot be changed, the extra bytes after the new array statement will be covered by 0;
(4) The hash value of the entire file is calculated, and bytes specified using a hash algorithm such as SHA-256. The PDF signature system always calculates the document signature hash of the whole PDF file, and starts from byte 0 to the end of the last byte in the file (but does not comprise signature value bytes);
(5) The hash value is encrypted by a private key of a signer, a hexadecimal coded PKCS#7 code is generated, and signature processing is carried out on the hash value;
(6) PKCS #7 encodes the overlay placeholder in a file stored on disk. The space not storing PKCS #7 codes is covered by 0;
(7) When the PDF file is reloaded in the parser, the versions in the memory and on the disk can be ensured to be identical;
(8) The signature is completed.
In the application, the validity verification of the electronic file can also be carried out:
(1) The PDF parser of the addressee (Adobe Reader or Acrobat, etc.) generates a hash value of the document by using the same algorithm used by the signer, and excludes the signature value;
(2) The encrypted hash in the document is decrypted using the public key of the signer;
(3) Comparing the decrypted hash value with a locally generated hash value;
(4) If they are identical, the signature is informed as a trusted signature.
The invention establishes a complete Distributed (DCS) design process control system through an informatization system integration technology, and establishes a standardized flow for a document/drawing compiling process by combining plug-in secondary development and integration technology of an office application platform. Establishing a general document/drawing compiling generating guide through a technical means, and carrying out standardized processing on the digital delivery; based on the virtual characteristics of the designed cloud platform, the desktop standardization of paperless application is realized under the framework of the existing virtual platform; and the integrated digital trusted signature system ensures the legitimacy and the safety of the electronic file.
The technical effects are as follows: and a series of problems in the design process are thoroughly eliminated.
1) Solving the problem of file homology (paper version file is different from editable file);
2) Solving the problem of non-standard template use (template default configuration, replacement and manual template configuration functions);
3) The problem of missing an opening chapter is solved;
4) Solving the problem of losing in the drawing circulation process;
