Problems solved by technology

[0004] At present, most of the encrypted fax devices on the market adopt the guard type. In addition to being unable to realize the automatic switching of plain and secret faxes, the guard equipment is also independent of the fax equipment. Data theft between fax devices, security risks still cannot be eliminated

Abstract

The invention discloses a fax encryption device based on an intelligent encryption key and an implementation method of the fax encryption device, and relates to the field of encrypted fax communication. Hardware encrypted faxes are realized through a traditional PSTN (public switched telephone network), a custom command is added in the fax implementation process to realize the fax encryption method on the basis of the fax T.30 protocol, fax data encryption is organically integrated in the fax communication process, and the hidden danger of guard type secret leakage is eliminated. The adopted intelligent encryption key is approved and certificated by the State Encryption Administration, adopts the state commercial cryptographic algorithm and can effectively ensure the reliability and the high efficiency of the cryptographic algorithm; the device can automatically switch unencrypted and encrypted faxes, is higher in safety, working efficiency and compatibility and can be widely applied to various industries such as government agencies, military, finance, telecom, enterprises and the like as well as users.

Description

technical field [0001] The invention belongs to the field of encrypted facsimile communication, and in particular relates to an encrypted facsimile device based on an intelligent encryption key and a realization method thereof. Background technique [0002] At present, fax has been more and more widely used in all walks of life in society, and it is a convenient way to send and receive text files. Faxes are transmitted through the world's most popular public switched telephone network (PSTN), so no matter which office in the world, as long as you have a fax machine, you can send and receive messages or faxes. Because it is transmitted on the public network, although measures such as dialing to prevent theft and eavesdropping have been taken. But when fax data is transmitted, its content is completely exposed on the PSTN, so some interception means can be used to intercept useful data and restore it. With the improvement of people's security awareness, their communication s...
