Step 201, card-reading terminal send physical interface to application module and control request.
In this step 201, it can be the current state that physical interface, closedown physical interface, inquiry physical interface are opened in request that physical interface controls request, and wherein, the current state of physical interface is for opening or closing.Application module is the special applications module downloaded within a smart card and install.
Further, before card-reading terminal sends physical interface control request to application module, card-reading terminal can send check code to application module.This check code is verified by application module, it is possible to preserve check results after verification.
Step 202, application module are after receiving physical interface control request, it is determined that whether the check code that card-reading terminal is sent verifies successfully, if it does not, enter step 203, if it is, enter step 204.
In this step, owing to application module is receiving physical interface control request, the check code that application module is likely to card-reading terminal is sent has verified, it is likely to and does not verify, or the result after verification is to verify successfully or verify unsuccessfully, it is thus desirable to confirm the check code of card-reading terminal is proved to be successful, then carry out the follow-up control to physical interface and operate.
Step 203, when application module determine to card-reading terminal send check code verify after unsuccessfully, to card-reading terminal return error message.
In this step, as the case may be, error message can represent and verifies unsuccessfully or do not verify.
Step 204, when application module determine to card-reading terminal send check code verify after successfully, by this physical interface control request be sent to authority module.
Wherein, authority module, on existing GlobalPlatform normative foundation, adds control of authority and physical interface controls function.GlobalPlatform is a comprising modules of JAVA operating system.
Step 205, authority module control request according to this physical interface received, and physical interface is controlled accordingly.
Further, authority module, after receiving the control request of this physical interface, searches in the authority information table prestored whether this application module has the authority of request control physical interface, if having authority, physical interface is controlled accordingly；If not having authority, it is possible to return authorization check failure to application module.
Concrete, when physical interface controls to ask to open physical interface for request, authority module opens physical interface；When physical control request closes physical interface for request, authority module closes physical interface；When physical interface controls the current state that request is requesting query physical interface, the current state of the physical interface that authority module inquiry preserves.
Further, the physical interface of smart card is being controlled in process, or complete after the control of the physical interface of smart card, smart card is all likely to be received the communication request of card-reading terminal, after smart card receives the communication request of card-reading terminal, this communication can be determined whether, concrete processing procedure following steps 206-step 211 according to the current state of physical interface:
Step 206, card-reading terminal send communication request to controlling module.
Wherein, this control module, on existing JCRE (JavaCardRuntimeEnvironment) normative foundation, increases the query function to physical interface state, and JCRE is the comprising modules of JAVA operating system.
After step 207, the module that controls receive this communication request, it is determined that whether this communication request asks to control application with physical interface carries out communication, if it is, enter step 208；If it does not, enter step 209.
Wherein, this physical interface controls application and is in the present embodiment 1 application module of smart card.
Step 208, when determine this communication request for request with physical interface control application carry out communication time, it is allowed to this card-reading terminal carries out communication.
Step 209, when determine described communication request be request with except physical interface control application except application carry out communication time, inquiry physical interface current state.
If the current state of the physical interface that step 210 inquires is for opening, it is allowed to this card-reading terminal carries out communication.
If the current state of the physical interface that step 211 inquires is for closing, refuses this card-reading terminal and carry out communication.
By the method that the above embodiment of the present invention 1 provides, by physical interface is controlled, avoid smart card physical interface under electric power thus supplied and be in the situation of open mode all the time, and card-reading terminal is when making requests on communication with smart card, the communication of card-reading terminal and smart card is controlled by the current state of physical interface, prevent the stolen brush of smart card, improve the safety of smart card.
Embodiment 2:
Based on same inventive concept, the physical interface control method according to the smart card that the above embodiment of the present invention provides, correspondingly, the embodiment of the present invention 2 additionally provides the physical interface of a kind of smart card and controls device, as it is shown on figure 3, specifically include:
