Problems solved by technology

[0004] At present, no effective way to solve the above-mentioned information security problems has been found. If the purpose of security is achieved through pure software, it is unsafe to some extent, because, as we all know, some small software or small programs can It can be cracked, so to effectively solve the above problems, it is necessary to invent a reasonable hardware solution

Embodiment 1

[0028] Embodiment 1: as figure 2 As shown, it is an information processing and conversion device with an information security system. It is a multifunctional machine with printing, copying, scanning, and fax functions. It can also be a printer, or a copier, or a scanner, or a fax. It can also be a combination of printing and copying, or a combination of copying, scanning and faxing. It consists of an information processing and conversion device main controller 1, a dynamic random access memory (DRAM) 2, a boot memory (Boot Rom) 3, information security system, and shell etc.; Described information security system has security chip 4; This security chip 4 is an integrated circuit chip with LPC interface, and one end has an interface and information processing and conversion equipment The interface of the main controller 1 is connected, and the other end has an interface connected with the boot memory 3; one end of the security chip 4 described in this embodiment is an LPC inter...

Embodiment 2

[0030] The difference from Embodiment 1 above is that the security chip 4 is connected to the boot memory 3 with an SPI interface through an SPI interface.

Embodiment 3

[0032] What is different from above-mentioned embodiment 1 is that described information security system also has a Key5, and safety chip 4 has an interface to be connected with Key5; Safety chip 4 also has USB interface, or MMC card interface, or SD card interface, or MS card One of the interfaces is connected to the corresponding interface of Key5; to be specific: according to the different Key used, the interface of the connected security chip 4 is also different. The optional Key here is USB Key (Device / Host / OTG), In this embodiment, the security chip 4 has a USB interface connected to the USB interface of the Key5.

Abstract

The present invention relates to a message processing and conversion device which is provided with an information security system, belonging to the electronic information security technique field. The message processing and conversion device comprises a master controller, a dynamic random access memory, an initiate memory, and the information security system provided with a security chip. The security chip is an integrated circuit chip. One side of the security chip has an interface connected with an interface of the master controller of the message processing and conversion device. The other side of the security chip has an interface connected with the initiate memory. The initiate memory is connected with the master controller only through the security chip. All the information which are interacted between the master controller and the initiate memory are gone through the security chip. The message processing and conversion device provided by the present invention has the advantages of that: any operation made for the initiate memory comprises reading and writing pass authenticate of the security chip; in addition, the security chip is an integrated circuit chip with low production cost and convenient use; and because of the security chip and Key, operations such as starting up, printing and so on are effectively monitored, so as to be in favor of managing office environment.

Description

technical field [0001] The invention relates to an information processing and converting device with an information security system, which belongs to the technical field of electronic information security, and in particular relates to printing, copying, scanning, fax machines and other devices with an information security system or a combination of at least two functions of these devices Multifunctional. Background technique [0002] After the information is processed by the computer, it is finally converted into visual and audio forms such as images or text and output. Information conversion and output devices are widely used. Among them, printers are very popular devices in both homes and offices, and multifunctional machines are office equipment that integrates two or more functions of printing, copying, scanning, and faxing. Across the two major fields of IT and OA, it has the characteristics of integration, digitization, small footprint, and high cost performance. Mor...
