Micro stock market data processing system using FPGA encryption card

Abstract

The invention discloses a micro stock market data processing system using an FPGA encryption card. The micro stock market data processing system comprises an FPGA module, an encryption and decryption module, an asymmetric algorithm module and a main control module; the encryption and decryption module, the asymmetric algorithm module and the main control module are separately connected with the FPGA module; the main control module and the asymmetric algorithm module are separately connected with an interface control and conversion unit; the FPGA module comprises a PCI protocol unit, a first storage module, a second storage module and the interface control and conversion unit; the PCI protocol unit transmits data to the interface control and conversion unit through the first storage module; the interface control and conversion unit transmits the data to the PCI protocol unit through the second storage module; and the encryption and decryption module comprises a third storage module, a fourth storage module and a command and state register. According to the micro stock market data processing system disclosed by the invention, the encryption and decryption module is arranged, so that high-speed encryption and decryption of SM1 can be realized; operation results grouped before can be output while the data is input; therefore, pipeline operation can be supported; and the data throughput speed is increased.

Description

technical field [0001] The invention relates to a microdisk system, in particular to a micro stock market data processing system using an FPGA encryption card. Background technique [0002] With the country's emphasis on information security, many domestic departments and enterprises currently require the use of domestic cryptographic algorithms to protect their information. Relevant laws clearly prohibit the use of plaintext methods or the use of foreign cryptographic algorithms, thus increasing the demand for domestic cryptographic algorithms , but also put forward higher requirements for the domestic encryption algorithm. In order to meet the requirements of servers, gateways and other equipment for the speed and security of encryption algorithms, many manufacturers have developed some encryption cards, which meet the above requirements to a certain extent. However, with the vigorous promotion of the 4G network, the number of users has increased significantly and each us...
