Abstract

The embodiment of the present invention discloses a safety protection device and method for an FPGA program download port, including a CPLD, a digital logic circuit is arranged in the CPLD, and the digital logic circuit includes several logic control units; the logic control unit is used for On-off control of memory and interface pins, and on-off control of memory and FPGA. The invention sets a multi-channel logic control unit through the CPLD to realize the connection between the memory and the corresponding pins of the interface pins, realizes the on-off connection of the memory, the interface pins, and the FPGA through the logic control circuit, and prevents malicious personnel from downloading malicious things to the FPGA through the AS port. The program ensures the security of the FPGA system.

Description

technical field [0001] The invention relates to the technical field of computer security, in particular to a security protection device and method for a FPGA program download port. Background technique [0002] FPGA (Field-Programmable Gate Array Field Programmable Gate Array) is a volatile programmable logic device, and the programs stored in it cannot be saved after the chip is powered off, so an external non-volatile storage device is required to save the FPGA. The program is loaded into the RAM (Random Access Memory, random access memory) inside the FPGA to run after the FPGA reads the program from the external memory after the next power-on. Downloading the FPGA program to the external memory needs to use the program download port of the FPGA, that is, the active serial AS (active serial) interface. The FPGA program is downloaded to the external memory by connecting a dedicated cable through the AS interface. [0003] like figure 1 As shown, each signal of the AS port...
