Embodiment Construction

[0013] Embodiments of the present invention will be described below with reference to the drawings. An embodiment is an image forming apparatus. Such as figure 1 As shown, the image forming apparatus includes a system board 100 . The system board 100 has input / output interfaces (not shown). The scanner engine 200, the printer engine 300, the operation panel 400, and the secure board 500 are all connected to an input / output interface (not shown) through the input / output interface. An input / output interface connects the hard disk drive 600 to the dongle board 500 .

[0014] The operation panel 400 includes a touch panel 401 and a key / 0-9 number key unit (hand-key / ten-key unit) 402 . The panel 400 has a liquid crystal display. The user operates keys provided on the operation panel 400 so that at least copying can be performed. The encryptor board 500 includes an IDE controller chip 501 , an encryption chip 502 and a key-programmable logic device (PLD) 503 . The IDE control...

Abstract

An encryption apparatus and an image forming apparatus are provided, in which measures are taken to prevent the encryption-key code from leaking outside. An encryption-key code is stored in a volatile memory that is soldered to a board. A lithium button-cell is used as backup power supply for the volatile memory. A wire that is provided on the board connects the lithium button-cell to the volatile memory.

Description

technical field [0001] The present invention relates to an encryption device and an image forming device. Specifically, the present invention relates to an encryption device and an image forming device in which measures are taken to prevent theft of an encryption key code used in encrypting data. Background technique [0002] In an image forming apparatus, image data read from a document may be stored in a recording medium such as a hard disk. The image data recorded in the hard disk is read so that an image represented by the data can be formed on the image transfer drum. The image is transferred from the drum to the paper. Image data is encrypted before being recorded on the hard disk and decrypted after being read from the hard disk. Therefore, classified data, personal data, etc. stored in the hard disk can be protected from unauthorized use even if the hard disk is disassembled and stolen. [0003] When an image forming device is reinstalled, an encryption function ...
