A hardware encryption card and encryption method

Abstract

The invention discloses a hardware encryption card and encryption method, and belongs to the technical field of data security. The hardware encryption card comprises a ZYNQ chip, a first encryption chip, a second encryption chip, a first USB interface, a second USB interface, a DDR3 storage unit, an EMMC storage unit and a random number generator, wherein the ZYNQ chip comprises an ARM processor and an FPGA module; the ARM processor is connected with the FPGA module through a high-speed on-chip bus; the FPGA module is connected with a server through the first USB interface; the FPGA module isfurther connected with the first encryption chip and the random number generator; the ARM processor is connected with the second encryption chip, the EMMC storage unit and the second USB interface; the first encryption chip and the second encryption chip provide more encryption algorithms; the encryption algorithms provided by the first encryption chip and the second encryption chip are different;the EMMC storage unit is used for storing a key; the DDR3 storage unit is used for caching the key in a work process of the hardware encryption card; and the second USB interface is used for an external expansion device.

Description

technical field [0001] The invention relates to the technical field of data security, in particular to a hardware encryption card and an encryption method. Background technique [0002] With the development of information technology and the popularity of the Internet era, information security technology has gradually been valued by people to deal with various information security threats. For some key industries, such as: banks, public security systems, etc., hardware encryption equipment must be used to improve the security of the system. The key must be stored locally in the hardware encryption system and cannot appear in the system memory, so the hardware encryption card comes into being. pregnancy. [0003] The current mainstream hardware encryption card is mainly composed of a main control module, an encryption module, a flash memory (flash) module, a random number generator and a communication interface module. Among them, the main control module is the core module o...

Problems solved by technology

[0004] The flash module capacity of the current hardware encryption card is relatively small, most of which only reach 1MB, and cannot realize massive key storage; at the same time, the communication interface module adopts the peripheral component interconnection standard (Peripheral Component Interconnect, PCI) interface to realize, resulting in hardware encryption The card is not convenient to carry, and it is different from plug and play
