Secure application directory

摘要

This disclosure relates to storing a secure application directory within a contactless smart card. The contactless smart card include secure memory area for storing software applications and may include a default application directory for listing the software applications stored within the contactless smart card to an external card reader. A second application directory is stored with an access key and a listing of a second set of software applications within the same contactless smart card. The second application directory includes improved application directory entries, where each application directory entry includes an application identifier, a starting memory block byte value, and a size byte value for each of the second set of software applications.

主权项

1. A computer-implemented method for storing multiple applications in single sectors of mobile device memory namespaces, comprising:
storing, for each application stored in a mobile device memory namespace, an application directory entry in a data memory block of an application directory in the mobile device memory namespace, each application directory entry comprising:
an application identifier (AID) for each corresponding software application stored in one or more data memory blocks of a sector of the mobile device memory namespace;a starting memory block number for a starting memory block in the sector of the mobile device memory namespace, wherein the starting memory block holds at least a part of a corresponding software application; anda size for the corresponding software application, the size defining a number of contiguous data memory blocks including the starting data memory block that store the entire corresponding software application.
