1 additionally provides a kind of physical interface control method of smart card, in conjunction with the modules in the smart card, the embodiment of the present invention 1
The flow chart of this method of offer is as shown in Fig. 2, specifically include:
Step 201, card-reading terminal send physical interface control request to application module.
In this step 201, physical interface control request can open physical interface for request, close physical interface, inquiry
The current state of physical interface, wherein the current state of physical interface is to turn on or off.Application module is within a smart card
The special applications module downloaded and installed.
Further, before sending physical interface control request to application module in card-reading terminal, card-reading terminal can be to
Application module sends check code.Application module verifies the check code, and check results can be saved after verification.
Step 202, application module determine the check code sent to card-reading terminal after receiving physical interface control request
Whether verification is successful, if not, 203 are entered step, if so, entering step 204.
In this step, since application module is receiving physical interface control request, application module may be to card-reading terminal
The check code of transmission is verified, it is also possible to do not verify, or verification after the result is that verify successfully or verify fail, therefore
It needs to confirm and the check code of card-reading terminal is proved to be successful, then carry out the subsequent control to physical interface and operate.
After step 203, the verification code check failure sent when application module is determining to card-reading terminal, returned to card-reading terminal
Error message.
In this step, as the case may be, error message can indicate verification failure or not verify.
After step 204, the verification code check success sent when application module is determining to card-reading terminal, by the physical interface control
System request is sent to authority module.
Wherein, authority module increases permission control and physics connects on existing Global Platform normative foundation
Mouth control function.Global Platform is a comprising modules of JAVA operating system.
Step 205, authority module control physical interface according to the physical interface control request received accordingly
System.
Further, authority module is looked into the authority information table prestored after receiving physical interface control request
It looks for whether the application module has the permission of request control physical interface, if having permission, physical interface is carried out corresponding
Control；If not having permission, authorization check failure news can be returned to application module.
Specifically, authority module opens physical interface when physical interface control request opens physical interface for request；When
When physical control request closes physical interface for request, authority module closes physical interface；When physical interface control request is to ask
When seeking the current state of inquiry physical interface, the current state for the physical interface that authority module inquiry saves.
Further, it is carried out in control process in the physical interface to smart card, or completes to connect the physics of smart card
After the control of mouth, smart card is all likely to be received the communication request of card-reading terminal, when smart card receives the communication of card-reading terminal
After request, it can determine whether this time to communicate according to the current state of physical interface, specific treatment process following steps
206- step 211:
Step 206, card-reading terminal send communication request to control module.
Wherein, which increases on existing JCRE (Java Card Runtime Environment) normative foundation
Add the query function to physical interface state, JCRE is the comprising modules of JAVA operating system.
After step 207, control module receive the communication request, determine whether the communication request requests and physical interface control
System application is communicated, if so, entering step 208；If not, entering step 209.
Wherein, physical interface control application is the application module of smart card in the present embodiment 1.
Step 208, when determine the communication request for request with physical interface control application communicated when, allow the card reading
Terminal is communicated.
Step 209, when determine the communication request be request in addition to physical interface control application using being led to
When news, the current state of physical interface is inquired.
If step 210, the current state of the physical interface inquired are to open, the card-reading terminal is allowed to be communicated.
If step 211, the current state of the physical interface inquired are to close, refuse the card-reading terminal and communicated.
The method that above-described embodiment 1 provides through the invention avoids smart card and exists by controlling physical interface
Physical interface situation in the open state always under electric power thus supplied, and card-reading terminal is making requests communication with smart card
When, the communication of card-reading terminal and smart card is controlled by the current state of physical interface, it is therefore prevented that the stolen brush of smart card improves
The safety of smart card.
