Abstract
The invention discloses a method and device for upgrading an intelligent card operation system module. The method includes the following steps that in the normal execution process of a commercial application program, if an upgrading starting order of the card operation system module is received, and state information of execution of a current program is backed up to a restoration point of an application program. After initialization of the leading program operation environment, skipping to a leading program instruct set is performed and the card operation system module is downloaded again. After upgrading is finished, information remaining in the internal storage is returned to the restoration point of the commercial program, thus the commercial application program is normally executed after upgrading is finished.
Description
Technical field
The present invention relates to smart card techniques, relate in particular to method and the device of realizing smart card COS module upgrade.
Background technology
COS(Card Operating System) be the operating system software residing in smart card, be similar to the DOS system on PC, but simply more than DOS system.COS is mainly used in receiving and processing the various information that extraneous (as mobile phone or card reader) issues smart card, carries out the extraneous various instructions that send (as authentication computing etc.), and the storage space in control card, to extraneous return response information etc.In general, smart card COS system comprises 4 parts: communication management module, safety management module, application processing module, document management module.
Smart card COS software often need to increase some business or change some function according to customer demand after smart card productization, needs smart card COS software to upgrade for this reason.Have at present the more similar scheme to smart card software upgrading: after intelligent card chip is resetted, in the normal implementation of commercial business, need after chip resets again, to adopt boot again to download COS module and operation.And conventionally after intelligent card chip resets, because smart card re-starts the initial work of applied environment, can cause the loss of state of business execution in card, for user's use makes troubles.Therefore in this scheme, require the upgrading of smart card COS must avoid carrying out between execution service period, thereby there is certain limitation.
Therefore, need to be method and the device of a kind of operating system module upgrading of smart card designs, can after resetting, carry out intelligent card chip the upgrading of COS.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of method and device of realizing smart card operating system module upgrade, can avoid carrying out the loss of state that COS upgrading causes business execution in card before intelligent card chip reset.
In order to solve the problems of the technologies described above, the invention provides a kind of method that realizes smart card operating system module upgrade, comprise the steps:
In the normal implementation of commercial applications program, if receive the starting and upgrading instruction of card operation system module, back up status information that present procedure carries out to application program restoration point, and after the initialization that completes boot running environment, jump to boot instruction set and complete the download again to card operation system module.
Further, after the initialization that completes boot running environment, jump to boot instruction set and complete the download again to card operation system module, specifically comprise:
After completing the initialization of boot running environment, if receive the upgrading download instruction in boot instruction set, the application program of down loading updating card operation system module, to program area and corresponding data field, and is returned to execution result executing after again downloading again.
Further, the method also comprises:
Boot instruction set is returned to application program restoration point, and commercial applications program is returned in redirect;
Commercial applications program enters the card operation system module main flow of renewal, by card operation system module main flow, according to the state that before the information recovery card operation system module upgrade of the program execution state of application program restoration point backup, program is carried out, continue the normal execution of commercial applications program.
In order to solve the problems of the technologies described above, the invention provides a kind of device of realizing smart card operating system module upgrade, comprise commercial applications program execution module and boot execution module, wherein:
Commercial applications program execution module, be used for carrying out commercial applications program, after the starting and upgrading instruction that receives card operation system module, back up the status information of current application program execution to application program restoration point, and after the initialization that completes boot running environment, jump to boot execution module;
Boot execution module, for completing the download again to card operation system module.
Further, if boot execution module is received the upgrading download instruction of card operation system module, the application program of down loading updating card operation system module, to program area and corresponding data field, and is returned to execution result executing after again downloading again.
Further,
Boot execution module, after the upgrading END instruction of receiving card operation system module, returns to application program restoration point, and commercial applications program execution module is returned in redirect;
Commercial applications program execution module enters the operating system module main flow after renewal, by this operating system module main flow, according to the state that before the information recovery COS module upgrade of the instruction executing state of application program restoration point backup, instruction is carried out, continue the normal execution of commercial applications program.
The present invention is because smart card externally keeps the consistance in communication in COS module upgrade process, therefore need not be as in the past, in the normal implementation of commercial business, need after chip resets again just newly downloaded the and operation COS module of duplicate removal, therefore in COS module upgrade process, the data in intelligent card chip internal memory are not lost, can after upgrading completes, according to the information retaining in internal memory, return to the restoration point of commercial program, thereby guarantee the normal execution of commercial applications program.
