Problems solved by technology

However, due to the limitation of the capacity of the smart card chip, the number of APIs implemented in the Java smart card operating system is limited. Therefore, the Java smart card operating system may not be able to meet the capabilities of Java smart card application development and operation, such as algorithms and related APIs, performance, etc.
[0004] In order to avoid that the Java smart card operating system cannot meet the development and operation of Java smart card applications, so when developing Java smart card applications, it is necessary to confirm the requirements of Java smart card application development and the interface implementation of Java smart card operating systems to avoid the development of Java smart card applications. The smart card application is using an interface not yet implemented in the Java Smart Card OS, or to upgrade an interface implemented in the Java Smart Card OS
[0005] If the Java smart card application development requirements and the interface implementation of the Java smart card operating system are not confirmed during the development of the Java smart card application program, the Java smart card application program will not be able to run, resulting in the inability to download and use the Java smart card application program

Abstract

This application relates to the technical field of smart cards, in particular to a Java smart card, including: Java smart card operating system, Java smart card application-specific interface provided by Java smart card operating system, secure storage area of ​​Java smart card hardware area, and internal operation of Java smart card operating system The user interface management module; the Java smart card application downloaded to the Java smart card calls the Java smart card application-specific interface, so that the user interface management module runs and downloads the user application program interface stored in the safe storage area. The Java smart card provided by this application can enable the Java smart card application program to call the user's required and self-developed interface through the Java smart card application-specific interface, so that even if the interface implementation of the Java smart card operating system is not confirmed before the application program is developed, it can also be used. It ensures that all Java smart card applications can be downloaded and used, making up for the missing functions of the Java smart card operating system.

Description

technical field [0001] The application relates to the technical field of smart cards, in particular to a Java smart card and a calling method of an application program interface thereof. Background technique [0002] A Java smart card application is an application developed based on the Java language and running on a smart card operating system that supports the Java smart card virtual machine. Like Java applications, it has the advantages of using natural language, easy development, one-time compilation, and multi-platform operation. [0003] In the Java smart card operating system, it is necessary to provide a large number of APIs (Application Program Interface, Application Programming Interface) for Java smart card application development to meet different usage scenarios and requirements. However, due to the limitation of the capacity of the smart card chip, the number of APIs implemented in the Java smart card operating system is limited. Therefore, the Java smart card ...
