Abstract: A method of loading a Java Card memory with a Java Card package through a Card Personalization Specification (CPS) flow. The method proposes to encapsulate the Java Card package destined to be loaded into the Java Card memory in an extra proprietary Data Grouping Identifier (DGI) added at the beginning of a standard DGI sequence. By adding the extra DGI containing a Java Card package at the beginning of the DGI sequence, the Java Card application writes the Java Card package into the Java Card memory. The Java Card package then receives the rest of the DGIs from the application and handles the personalization process by writing itself the personalized data into the memory.

Abstract: There is described a method for Java Card application memory footprint optimization which relies on the separation in advance of the code related to the personalization from the rest of the code. It allows this code to perform the personalization of an application installed from a main package while being itself included and installed from a separated package dedicated to the personalization, namely the Card Personalization Specifications (CPS) package. This way, the CPS package and all the code inherent to the personalization can be removed once all the personalization steps have been completed.
