Description
Technical Field
The application relates to the technical field of smart cards, in particular to a method and a device for updating and managing a smart card system package.
Background
With the popularization of smart terminals and smart cards, the smart terminals and smart cards have been widely used in various fields in our society and life. Two types of software packages, namely a mask system package and a download package, exist on the Java Card intelligent Card, the mask system package is a basic function package provided by the Java Card operating system, and provides a basic framework and a function service of the Java Card operating system along with the operating system.
The requirement for updating the operating system of the issued smart card exists in the actual use process, the updating of the mask system is also included for updating the functions of the smart card, a user does not need to change the card and directly updates the card, the card does not need to be recycled, changed and issued for the second time, the updating cost can be effectively reduced, personalized sensitive data of the user can be reserved, convenience is brought to the user, and the experience effect is good.
However, the application package includes calls to basic functions provided by the system package, for example, an object including a class in the system package, a reference to a class and a static public method in the system package, and the like are instantiated in the application. When the application package is downloaded, the class address or the method address called in the byte code is generally fixedly linked, so that a search step in the execution of the application is omitted, and the execution speed of the application is optimized. However, the link relationship is destroyed after the system package is updated, because the address or method address of the class referred to in the updated system package is changed, the reference address of the application package on the card to the system package is wrong, and the application cannot be used normally.
In the face of the technical problem, the traditional solution is to keep the constant pool component and the reference component when the application package is downloaded, and after the system package is updated, re-link all downloaded packages on the card by using the constant pool component and the reference component, and update the downloaded packages into a correct link relation; and the operating system is required to provide a system package object updating function module for traversing all objects on the card, and the instantiated object of the class of the mask system before updating and the class address corresponding to the updated system are linked again, so that the class address quoted by the object is correct, and the updated object can be normally accessed.
However, the implementation of the above solution has some disadvantages: constant pool components and reference components which are not needed when the application runs need to be saved, and space resources are occupied; in addition, after the system package is updated, traversal and link are required to be performed on the data on the card again, so that the time consumption is long, and the user experience is influenced.

the reference relation building module is used for downloading an application package on the intelligent card operating system of the initial version, and building a reference relation between information needing to reference the mask system of the initial version in the application package and referenced information in the mask system of the initial version based on corresponding index values in the secondary reference table;
the reference table updating module is used for downloading an application package on the smart card operating system of the initial version, and establishing a reference relation between information needing to reference the mask system of the initial version in the application package and referenced information in the mask system of the initial version based on corresponding index values in the secondary reference table;
the reference relation updating module is used for establishing a reference relation between information needing to reference the updated version mask system in the application package and referenced information in the updated version mask system based on the corresponding index value in the updated secondary reference table; wherein the content of the first and second substances,
and the reference table entry in the secondary reference table corresponds to the index value, the reference table entry in the secondary reference table corresponds to the physical address of the reference information referenced by the mask system package, and the index value in the secondary reference table is in a preset index value range.
7. The smart card system package update management device of claim 6, wherein:
and the corresponding relation of original information belonging to the mask system in the updated version mask system package corresponding to the reference table item of the updated secondary reference table is unchanged, and the newly added information in the updated version mask system package is added corresponding to the reference table item of the updated secondary reference table on the basis of passing through the secondary reference table, and is configured with a corresponding index value.
8. The smart card system package update management device according to claim 6, wherein in establishing a reference relationship between information in the application package that needs to refer to the updated version mask system package and information referred to in the updated version mask system package based on a corresponding index value in the updated secondary reference table:
and the application package acquires the corresponding physical address of the reference information referenced by the mask system package through the updated secondary reference table.
9. The smart card system package update management device of claim 6, wherein:
and the intelligent card operating system is allocated with a logical address for storing the index value of the mask system package or the updated version mask system package.
10. The smart card system package update management device of claim 6, wherein:
the updated version mask system package is consistent with the mask system package in the logic address of the intelligent card operating system.
