Description
Technical field
The present invention relates to usb communication technical field, specifically block and its a kind of hardware digital realized by USB interface is awarded
Authorization module and its authorization method.
Background technique
RS232 interface is very widely used in modern industrial equipment.There is RS232 interface in traditional PC machine,
But with the development of computer technology, support the USB standard interface of hot plug gradually instead of RS232 interface.This just makes
The communication obtained between some PC machine and industrial equipment becomes difficult.Most of in response to this is by equipment
Increase USB/RS232 bridge joint device (such as CP2102, CH340 etc.) after RS232 interface, the end PC passes through USB interface virtual one
RS232 interface solves the problems, such as.
Existing more mature product authorization method is added by the USB interface insertion U-shield in computer (PC machine), USB
The hardware such as close dog are realized by the method for embedded digital certificate, are common in e-bank, critical software, for awarding for software
Power uses.But for solution can be licensed there has been no preferable at present with independently operated instrument and equipment.
Summary of the invention
The purpose of the present invention is to provide a kind of hardware digital authorization module realized by USB interface and its authorized parties
Method, according to equipment by USB/RS232 bridge device after can only be communicated with PC machine the technical issues of, design it is a can with it is this
The authorization module of class USB interface (interface after USB/RS232 bridge joint device conversion) communication, to solve in above-mentioned background technique
The problem of proposition.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is that:
A kind of hardware digital authorization module realized by USB interface, including main control chip, memory, the master control core
Piece is communicatively coupled with memory using general serial Peripheral Interface, and the memory is for storing authorization encryption key, institute
It states main control chip and Communications Authorization is carried out by USB interface and the device controller to authorisation device, and in automatic removing memory
Used authorization encryption key.
It further, further include power module, the power module provides power supply for the main control chip.
Further, the authorization method of the hardware digital authorization module realized by USB interface, including walk as follows
It is rapid:
A. authorization encryption key is stored in memory；
B. authorization module is inserted into in the class USB interface of authorisation device；
C. Authorized operation will be automatically performed by software by USB interface and authorization module to authorisation device；
D. after authorizing successfully, USB authorization module will remove used authorization encryption key in memory automatically.
The beneficial effects of the present invention are:
The present invention provides a kind of hardware digital authorization module and its authorization method realized by USB interface, authorized party
Formula is simple and convenient, after authorization module storage authorization encryption key, can be automatically performed after inserting instrument class USB interface to instrument
Authorized operation.
Detailed description of the invention
The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
Fig. 1 is present system frame diagram.
Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction with attached drawing, it is clear that described implementation
Example is a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill
Personnel's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
As shown in Figure 1, the present invention provides a kind of hardware digital authorization module realized by USB interface, including master control core
Piece, memory, the main control chip are communicatively coupled with memory using general serial Peripheral Interface, and the memory is used for
Storage authorization encryption key, the instrument for licensing to needs carries out effectively preventing unexpected use using management, described
After module is on the USB interface for be inserted into instrument, main control chip is carried out by USB interface and the device controller to authorisation device
Communications Authorization, it is automatic to remove used authorization encryption key in memory after authorizing successfully.
The invention also includes battery module, the power module provides power supply for the main control chip.
The authorization method of the hardware digital authorization module for USB device, includes the following steps:
A. authorization encryption key is stored in memory；
B. authorization module is inserted into the class USB port of USB device to be authorized；
C.USB equipment and authorization module will be automatically performed Authorized operation by software；
D. after authorizing successfully, USB authorization module will remove used authorization encryption key in memory automatically.
By the authorization method for the hardware digital authorization module that USB interface is realized, also not fully it is limited in by USB and connects
Mouth is realized.Equipment for there was only RS232 interface or CAN interface can also be come by adjusting the interface of the authorization module
It realizes, implementation steps are constant.
The embodiments of the present invention described above are not intended to limit the scope of the present invention, any in the present invention
Spirit and principle within made modifications, equivalent substitutions and improvements etc., should be included in claim protection model of the invention
Within enclosing.
