Description
Technical field
The invention belongs to field of communication technology more particularly to command handling methods and device.
Background technology
For CCID (Chip Card Interface Device, intelligent card interface device), host operating system can under
The quasi- CCID orders of issue of bidding documents, the operating systems such as Window 7 and Windows XP can also issue smart card standard APDU
(Application Protocol Data Unit, Application Protocol Data Unit) is ordered, this influences whether CCID equipment
SCSI (Small Computer System Interface, small computer system interface) is communicated.For example, for using
USB (Universal Serial Bus, universal serial bus) Key (key) equipment complex in the channels CCID and the channels SCSI,
When middleware is communicated using SCSI with equipment, if host operating system issues CCID orders, inserting instruction mistake can be caused,
To influence SCSI communications.
Invention content

Specific implementation mode
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Fig. 1 shows the implementation flow chart of command handling method provided in an embodiment of the present invention, and details are as follows：
In step S101, when detecting CCID orders, the type of the CCID orders is obtained.
Preferably, when detecting CCID orders, the type for obtaining the CCID orders is specially：When detecting CCID orders
When, receive a data packet of the CCID orders；The type of the CCID orders is determined according to the data packet of reception.
In embodiments of the present invention, when detecting CCID orders, a data packet of CCID orders is first received, according to connecing
The first character section of the data packet of receipts determines the type of the CCID orders.Herein, by first receiving a number of CCID orders
According to packet, all data packets without directly receiving CCID orders improve communication efficiency.
In step s 102, if the CCID orders are standard CC id commands, the CCID orders are handled.
Wherein, standard CC id command refers to the non-order for sending APDU in the order that CCID protocol defines, such as PC_
To_RDR_lccPowerOn, PC_to_RDR_lccPowerOff, PC_to_RDR_GetSlotStatus etc..
If the CCID orders are standard CC id commands, the CCID orders are directly handled, without walking APDU flows.
Preferably, handling the CCID orders includes：Receive the remaining data packet of the CCID orders；Handle CCID lives
It enables；Returning response information.
In step s 103, if the CCID orders are self-defined CCID orders, and COS restrictions are led to using the channels SCSI
Letter, then do not handle the CCID orders.
Wherein, self-defined CCID orders refer to customized completion COS (Chip Operating System, the interior behaviour of piece
Make system) the CCID orders of function.
In embodiments of the present invention, it being communicated using the channels SCSI if COS has determined, the channels CCID are unavailable,
Therefore the CCID orders are not handled.
Preferably, not handling CCID orders includes：Abandon the data packet received；Return to error message.
Herein, it returns to error message and is specifically as follows return inserting instruction error message.
In step S104, if the CCID orders are self-defined CCID orders, COS is not limited to be led to using the channels SCSI
Letter, and COS has turned on the channels CCID, then uses the CCID orders of the APDU flow processings in the channels CCID.
Preferably, using the APDU flow processings in the channels CCID, the CCID orders include：Receive the residue of the CCID orders
Data packet；Use the CCID orders of the APDU flow processings in the channels CCID；Returning response information.
In step S105, if the CCID orders are self-defined CCID orders, and COS does not open the channels CCID, then does not locate
Manage the CCID orders.
Preferably, not handling CCID orders includes：Abandon the data packet received；Return to error message.
Herein, it returns to error message and is specifically as follows the ungratified error message of return condition.
Preferably, it if the CCID orders are self-defined CCID orders, is somebody's turn to do using the APDU flow processings in the channels CCID
Before CCID orders, this method further includes：Judge whether to receive self-defined APDU judgements order, if so, judgement COS has been opened
Open the channels CCID；If it is not, then judging that COS does not open the channels CCID.
In embodiments of the present invention, self-defined APDU judgements order is the order for being exclusively used in opening the channels CCID, if receiving
Judge to order to self-defined APDU, then judges that COS has turned on the channels CCID.
Fig. 2 shows the implementation flow charts for the command handling method that another embodiment of the present invention provides, with reference to Fig. 2：
In step s 201, when detecting CCID orders, the type of the CCID orders is obtained；
In step S202, judge whether the CCID orders are standard CC id command according to the type of the CCID orders, if
It is to then follow the steps S203；If it is not, thening follow the steps S204；
In step S203, the CCID orders are handled；
In step S204, judge whether COS limits the channels SCSI and communicated, if so, thening follow the steps S205；If
It is no, then follow the steps S206；
In step S205, the CCID orders are not handled；
In step S206, judge whether COS has turned on the channels CCID, if so, thening follow the steps S207；If it is not, then holding
Row step S205；
In step S207, the CCID orders of the APDU flow processings in the channels CCID are used.
For using the CCID USB Key equipment complexes in the channels CCID and the channels SCSI, the order received may be
CCID orders or scsi command.Scsi command includes standard SCSI command and APDU orders.CCID orders include standard CC ID
Order and self-defined CCID orders.If what is first received is standard SCSI command, need to immediately treat the response standard
Scsi command does not influence COS selection protocol types.If what is first received is the APDU orders in the channels SCSI, follow-up limit makes
It is communicated with SCSI protocol.During restriction is communicated using SCSI protocol, if receiving scsi command or mark
Quasi- CCID orders, then handled；If receiving the other kinds of CCID orders in addition to standard CC id command, do not locate
Reason, and return to error message.If what is first received is standard CC id command, simultaneously returning response is handled.If what is first received is
Self-defined CCID orders then judge whether to receive self-defined APDU judgements order, if so, handling the self-defined CCID lives
It enables；If it is not, not handling the self-defined CCID orders then, and returns to condition and be unsatisfactory for error message.
It should be understood that in embodiments of the present invention, size of the sequence numbers of the above procedures is not meant to the elder generation of execution sequence
Afterwards, the execution sequence of each process should be determined by its function and internal logic, the implementation process structure without coping with the embodiment of the present invention
At any restriction.
The embodiment of the present invention is by when detecting CCID orders, obtaining the type of the CCID orders, if the CCID orders
It is standard CC id command, then directly handles the CCID orders without walking APDU flows, if the CCID orders is self-defined CCID lives
It enables, then just uses the CCID orders of the APDU flow processings in the channels CCID when only COS opens the channels CCID, thus, it is possible to just
The CCID orders that often processing host operating system issues, and the normal use in the channels SCSI is not influenced, it is used to enhance
The communication stability of the CCID USB Key equipment complexes in the channels CCID and the channels SCSI.
