Multi-USB cryptographic module concurrent access system and method based on Ethernet interface

Abstract

A multi-USB cryptographic module concurrent access system based on an Ethernet interface comprises a main control board, a plurality of USB cryptographic modules and a software system module running on the main control board, the main control board is connected with the USB cryptographic modules through USB interfaces, and the software system module runs through a plurality of USB cryptographic module concurrent access algorithms. A plurality of USB password modules connected to the main control board are accessed concurrently, a universal network access interface is provided for a user, and the main control board provides a hardware operation environment for the concurrent access algorithm. Compared with the prior art, the USB password module is used for replacing a PCI-E password card to achieve the functions of key management and password service, and the research and development cost and the production cost of products are reduced. And the concurrent work of the main control board and the plurality of USB password modules is realized through a concurrent access algorithm, so that the overall performance of the system is improved. The network interface is used as the access interface of the system, so that the integration requirement of an application platform on a special driver is avoided, and the application and integration difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of safe processing of digital information, in particular to a concurrent access system and method for multiple USB cryptographic modules based on an Ethernet interface. Background technique [0002] According to the definition of a cryptographic module by the National Cryptography Industry Standardization Technical Committee, all hardware, software or firmware that is included in the cryptographic boundary and realizes security functions can be called a cryptographic module. As a typical application of a cryptographic module, a cryptographic card is often used to provide hardware-based key management and cryptographic services for computer systems. Compared with traditional software cryptographic technical solutions, the cryptographic algorithm based on the cryptographic card is faster and faster. The security is higher, so the password card is the core component of the commercial information security system...
