FPGA encryption protection method, system and server

Abstract

A FPGA encryption protection method, system and server are provided. That method comprises the steps of: The key is arranged in the ROM unit of the PCI-E card; The encryption and decryption module ofthe PCI-E card encrypts the configuration file of the FPGA according to the key to obtain the encrypted configuration file; the encrypted configuration file is stored to a storage unit; During serverpower-on startup, The encryption and decryption module of the PCI-E card decrypts the encrypted configuration file according to the key to obtain the configuration file; The configuration file is loaded into a RAM cell in the FPGA for execution. By adopting the scheme provided by the embodiment of the application, the confidentiality of the FPGA configuration file can be ensured, the program security of the FPGA is effectively protected, and malicious reading of the configuration file by malicious personnel such as hackers is prevented. In addition, the scheme does not need to change the hardware structure of the server motherboard, which has low cost and strong operability, and increases the flexibility of the design.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to an FPGA encryption protection method, system and server. Background technique [0002] FPGA is a programmable logic device, which is used to implement various algorithms, control, digital logic and other functions, and has been widely used in electronic information, communication engineering and other fields. FPGA also has a wide range of applications in servers, such as realizing power control, logic algorithms, acceleration units, etc., and is an indispensable part of servers. [0003] Since the FPGA is a volatile device, its internally stored program will be lost after power failure, so it is necessary to use an external non-volatile memory (such as Flash) to store its program file. figure 1 It is a schematic diagram of an FPGA configuration file storage method in the prior art, such as figure 1 As shown, the configuration file of the FPGA is stored in the Flash ...
