The invention provides a TPCM board card based on an FPGA and a cryptographic chip. The TPCM board card comprises an FPGA chip, a cryptographic chip, an FPGA configuration chip, a random number generator, a power supply chip, a PEIE bus physical socket, and a crystal oscillator. The FPGA chip is connected with the cryptographic chip, the FPGA configuration chip, the random number generator, the power supply chip, the PEIE bus physical socket and the crystal oscillator, separately, and is used as a control unit of the TPCM board card to control encryption and decryption, digital signature and the work process of trusted computing. The cryptographic chip is used to load a cryptographic algorithm for high performance public key encryption and high performance block cipher encryption. The FPGAchip on the board card acts as the control unit and controls the cryptographic chip to implement SM2, SM3, and SM4 cryptographic algorithms to guarantee the security of data processing. In addition,the board card provides IIC and SPI interfaces to control the BMC and BIOS on the server, respectively, to achieve trusted boot control of the server.
Description
technical field [0001] The invention relates to the technical field of server boards, in particular to a TPCM board based on an FPGA and a cryptographic chip. Background technique [0002] Trusted Platform Control Module TPCM is a branch of the trusted computing research field, proposed by academician Shen Changxiang, TPCM is in its infancy in my country at present, and has not yet been applied on a large scale. TPCM is the core control module of the trusted computing platform, which physically provides three trust roots for trusted applications: trusted measurement root RTM, trusted storage root RTS and trusted reporting root RTR. Based on this, the trusted measurement function, trusted storage function and trusted reporting function of the trusted computing platform are extended. [0003] The TPCM idea is based on cryptographic algorithms, protects the confidentiality of system programs and key data, authenticates users who access the system, and establishes a trust chain...
