Embodiment Construction

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0031] Such as figure 1 As shown, the equipment board applying the digital certificate authentication module of the present invention needs to reserve a slot for the digital certificate authentication module, and use the UART interface to communicate with the digital certificate authentication module of the present invention through a dedicated protocol. The device sends the original data and digital signature result (the length of the signature result is determined by the selected digital s...

Abstract

The invention relates to the technical field of Public Key Infrastructure (PKI), and provides a digital certificate authentication device and a digital certificate authentication system. The digital certificate authentication device comprises a software portion and a hardware portion, wherein the software portion comprises a COS and a guide system, the hardware portion comprises hardware loading the COS and the guide system, and the COS comprises a UART transmission and management module, a hardware drive module, a function module, an algorithm library, a communication and instruction dispatch module and a main function module. The digital certificate authentication device and the digital certificate authentication system can meet the requirements that an equipment hardware structure is not changed and the minimum integrated development workload is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of PKI (Public Key Infrastructure, public key infrastructure), in particular to a digital certificate authentication device and a digital certificate authentication system. Background technique [0002] Due to the rapid development of information technology, more and more attention is paid to the integrity of information, and the application fields of equipment certificates are also becoming wider and wider. At present, servers, smart terminals and other devices mainly use the following three forms to integrate device certificates to protect the integrity of transmitted information: First, adopt the "soft certificate" method, and the device certificate and key are stored in the device in the form of files. Algorithm software realizes the digital signature and verification of information; the second is to increase special hardware devices, such as PCI / PCI-E cards, IC cards and card readers, USBKey, et...
