A configuration file decryption method, device, equipment and readable storage medium

Abstract

The present invention discloses a configuration file decryption method provided by the present invention. It is necessary to obtain the configuration data of the decryption module first, and then configure the reconfiguration area into a decryption module through the reconfiguration module of the FPGA according to the configuration data of the decryption module. The decryption module is set inside to avoid the storage of the key, thereby reducing the cost of the FPGA-based operating system. At the same time, because the reconfiguration area is configured as a decryption module, the reconfiguration area can be flexibly configured as different decryption modules, thereby effectively increasing the flexibility and applicability of user operations. The present invention also provides a configuration file decryption device, a configuration file decryption device, and a computer-readable storage medium, which also have the above beneficial effects.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a configuration file decryption method, a configuration file decryption device, a configuration file decryption device and a computer-readable storage medium. Background technique [0002] At this stage, the security of configuration files of FPGA (Field Programmable Gate Array) is getting more and more attention from companies. In the overall development and testing environment of FPGA IP multiplexing, anti-piracy and anti-infringement are important Sex is becoming more prominent. Usually, the FPGA and the external MCU with encryption function are used to cooperate with each other, and the parameters of the FPGA are configured through the external MCU, and the configuration mode of the FPGA can be the slave serial mode and so on. [0003] However, at this stage, if an external MCU is used to encrypt data, the entire system needs an additional chip support circuit; at ...

Problems solved by technology

[0003] However, at this stage, if an external MCU is used to encrypt data, the entire system needs an additional chip support circuit; at the same time, the corresponding key needs to be stored in the FPGA, and the key usually needs to be stored in a volatile device with a battery that is always powered on. storage area

This will increase the material cost and hardware design complexity
