FPGA dynamic configuration system based on cloud encryption

Abstract

The invention relates to an FPGA, a microprocessor, dynamic configuration of the FPGA, encryption configuration of the FPGA and cloud encryption, in particular to a FPGA dynamic configuration method,which is characterized in that encrypted configuration data is obtained by the microprocessor through the cloud through cloud encryption, decryption is carried out by using a decryption algorithm built in the microprocessor, and then the FPGA is dynamically configured by using the decrypted data. According to the invention, the configuration data of the FPGA is stored in the cloud for strict protection; the microprocessor acquires the data from the cloud through the encryption channel, decrypts the encrypted data and then uses the decrypted data for FPGA configuration; configuration data are protected to the maximum extent, illegal acquisition and use are prevented, remote dynamic configuration can be carried out on the FPGA, and the effects of being good in confidentiality effect and flexible in configuration are achieved.
