Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0037] The present invention proposes a data board for data encryption and decryption transmission, such as figure 1 As shown, it includes:

[0038] Power module 1, which outputs four voltages VCC, VDD, VKK and VDDS_DDR to supply power for different chips;

[0039] The DC-DC boost converter 2 is connected to the USB chip 3 and the safety memory 4 respectively, and is used to output a fixed DC voltage to supply power to the USB chip 3 and the safety memory 4;

[0040] The safety memory 4 and the flash memory chip 5 are all connected to the integrated chip 6, and the safety memory 4 passes the chip protocol identification authentication of Xilinx Company to decrypt the flash memory chip 5, and the integrated chip 6 reads the flash memory chip 5 and obtains the program to start running;

[0041] The first Micro SD card holder 7 and the second Micro SD ca...

Abstract

The invention discloses a data board for data encryption and decryption transmission, which comprises a power supply module and a DC-DC boost converter, a USB chip, a safety memory, a flash memory chip, an integrated chip, a Micro SD card seat, an N-type MOS tube, an indicating lamp external interface, a crystal oscillator, a PHY gigabit network chip, a microprocessor monitor with a watchdog timer, an AND gate, a network transformer, a network port, an RS-232 conversion chip with ESD protection, a DDR terminal voltage stabilizer, a DDR3 memory bank, an SW1, tortoise key, an SW2 tortoise key and a USB interface.. The power supply module can output four voltages VCC, VDD, VKK and VDDS _ DDR to supply power to different chips, and meanwhile, the power supply module encrypts and decrypts the power supply module in the data transmission process, so that the safety is ensured.

Description

technical field [0001] The invention relates to a data board, in particular to a data board used for data encryption and decryption transmission. Background technique [0002] With the rapid development of data transmission technology in the direction of high speed and stability, people have higher requirements for the security of data transmission. Data encryption is one of the most reliable ways to protect information. It uses cryptographic technology to encrypt information and realize information concealment, thereby protecting the security of information. The traditional data board can no longer meet people's requirements for the security of data transmission, and the traditional data board contains different chips, so different power modules are needed to supply power to different chips, so that the data board is large in size and low in cost. Then it becomes higher. Contents of the invention [0003] In view of the above problems, the present invention provides a ...
