Internet of vehicles multi-data type encryption method and system based on FPGA

The invention relates to the technical field of data encryption, and particularly discloses an Internet of Vehicles multi-data type encryption method and system based on an FPGA (Field Programmable Gate Array), and the method comprises the steps: collecting various data of a vehicle, and classifying the various data according to different data transmission types; and the FPGA encryption module is adopted to encrypt different types of data by adopting different encryption algorithms. By using the reconfigurable FPGA chip, various encryption algorithms (a symmetric encryption algorithm and an asymmetric encryption algorithm) are realized in the same chip, so that different encryption algorithms are selected according to data types, and the encryption efficiency and security can be effectively improved. Meanwhile, according to an encryption scheme for different data types, the security and reliability of sensitive information in the Internet of Vehicles can be better protected. By utilizing the reconfigurability
