Hard copy control system based on national commercial cipher algorithm

Abstract

The invention relates to a hard copy control system based on a national commercial cipher algorithm, comprising a main control module, a hard copy component, a human-computer interface module, and a network communication module. The main control module comprises a random access memory unit, a flash memory unit, and a main control unit. The main control unit is connected with the hard copy component, the human-computer interface module, the network communication module, the random access memory unit and the flash memory unit. The system further comprises a national cipher algorithm module used for providing an SM1 / SM2 / SM3 / SM4 algorithm and connected with the main control unit. Compared with the prior art, the confidentiality of the work information of the hard copy component is ensured and information leakage is prevented while the integrity and correctness of the work information are ensured, and the information security risk of the existing hard copy component is solved.

Description

technical field [0001] The invention relates to the field of information security, in particular to a hard copy control system based on a national commercial encryption algorithm. Background technique [0002] For the current hard copy components, such as multi-function machines, printers and other hard copy components, there are mainly the following potential safety hazards. [0003] (1) Potential security risks of data storage [0004] During the processing of printing, copying, and scanning jobs, there will be cached job information inside the device. Whether it is a hard disk or a solid-state disk, the information will not disappear after the device is powered off. If these hard drives or SSDs are stolen, all cached job information is leaked. [0005] (2) Security risks of firmware upgrade [0006] Firmware is the software that is responsible for the most basic and bottom-level work of a system. Hard copy components such as multi-functional all-in-ones and printers ha...
