Abstract

The invention discloses a method based on PCI-E interface full algorithm cryptographic card, including: a cryptographic algorithm module, a FLASH memory, a PCI-E bus interface, a random numb generator, and an FPGA master control chip with NIOS soft core processor, wherein a PCI-E IP core and an algorithm state machine are integrated in the FPGA master control chip. The cryptographic algorithm module comprises a symmetric key encryption SM4 algorithm chip, a symmetric key encryption SM1 algorithm chip and an asymmetric key encryption SM2 algorithm chip. The invention also discloses an encryption method of the cipher card. The invention provides a high-performance full-algorithm cryptographic card, which simultaneously reduces the complexity of hardware circuit and energy consumption, improves the key operation speed, and the cryptographic card adopts a home-made cryptographic algorithm, so that the user's key is most securely protected.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a full-algorithm encryption card based on a PCI-E interface and an encryption method thereof. Background technique [0002] PCI-Express (peripheral component interconnect express) is a high-speed serial computer expansion bus standard. Its original name is "3GIO", which was proposed by Intel in 2001 to replace the old PCI, PCI-X and AGP. bus standard. PCIe belongs to high-speed serial point-to-point dual-channel high-bandwidth transmission. The connected devices allocate exclusive channel bandwidth and do not share bus bandwidth. It mainly supports active power management, error reporting, end-to-end reliable transmission, hot swapping and quality of service ( QOS) and other functions. After PCI-SIG (PCI Special Interest Group) certification and release, PCIe was renamed "PCI-Express", or "PCI-E" for short. Its main advantage is the high data transmission rate, th...
