Abstract
The network document transmission system includes the digital sign process module, the document encrypting/decrypting module and the document process module. If the user at the end of transferring the document wants to encrypt the document to be transferred, the document encrypting/decrypting module encrypts the document by using the public key of the receiver at the receiving end. Then, the document process module transfers the encrypted document through the network to the receiving end. With the document being received, the user at the receiving end by use of the encrypting/decrypting module and the own private key decrypts the encrypted document so as to obtain the content of the document. The sign can be combined with the document by using the digital signal process module and the own private key to generate the information sequence.
