Abstract
The invention relates to an ELF automatic upgrade control method for a Java smart card. The method comprises the following steps: performing data docking with an application on the Java smart card through a localized data migration interface provided by the Java smart card; obtaining an ELF upgrade session coded as an APDU response code, constructing a dynamic decision tree, and performing dynamic arrangement of an instruction stream; triggering an application upgrading instruction according to the current session state, and performing application upgrading on the Java smart card; judging whether the application upgrading instruction is executed successfully or not according to the return code; and if execution of the application upgrading instruction fails, triggering execution of application rollback, application reservation or application discarding.
