Abstract

The invention discloses a fax encryption method, device and equipment based on a national secret algorithm, and a medium. The fax encryption method comprises the following steps: key distribution: loading a fax data symmetric cryptographic operation key in a UKEY offline mode; threshold key sharing: issuing the data encryption key protection key of the key service center to the fax cipher machine through a threshold key sharing technology; and secure message packaging: performing secure encryption / decryption transmission on the fax data by adopting a national commercial password algorithm, performing encryption / decryption on the data by using a national commercial password SM1 symmetric cryptographic algorithm, and performing integrity verification on the data by using a national commercial password SM3 abstract cryptographic algorithm. According to the invention, secure encryption of the fax data can be realized, and security assurance is provided for the fax data. In the aspect of security assurance, a key distribution technology is adopted to provide a data security encryption / decryption key for a user, and data security assurance during transmission of the fax data is provided.

Description

Technical field [0001] The present invention relates to the field of fax data secure transmission technology, and more particularly to a fax encryption method, apparatus, apparatus, and media based on national algorithm. Background technique [0002] The fax is the main tool for modern communication. It is used to transfer the text, chart, image, etc. recorded on paper, and then transfer from the sender from the transmitting end, and reproduce the working mode on the recording paper of the receiving end. It not only transmits the content of the document, but also the form of the document, the delivery of information is true, with telegraph, telephone, electrical transmission and other devices are unparalleled. As an important still image communication method of information society, the knowledge economy era, the basic characteristics of "real-time record" and "real-time transfer" can meet the fast, true, accurate and full requirements of information delivery, not only It has been...
