METHOD AND DEVICES FOR INSTALLING AND RETRIEVING LINKED MIFARE APPLICATIONS
First Claim
1. A method for installing linked MIFARE applications in a MIFARE memory being configured as a MIFARE Classic card or an emulated MIFARE Classic memory, the method comprising storing the first linked MIFARE application in a first free sector of the MIFARE memory, storing the second linked MIFARE application in a second free sector of the MIFARE memory and writing link information indicating this second sector in a link information memory location of the first sector where first linked MIFARE application has been stored, and repeating the steps of storing linked MIFARE applications and writing link information until the last linked MIFARE application has been stored.

Abstract
A method for installing linked MIFARE applications (TK1-A, TK1-B, TK1-C) in a MIFARE memory (MM) being configured as a MIFARE Classic card or an emulated MIFARE Classic memory comprises storing the first linked MIFARE application (TK1-A) in a first free sector of the MIFARE memory, storing the second linked MIFARE application (TK1-B) in a second free sector of the MIFARE memory and writing link information (LK) indicating this second sector in a link information memory location of the first sector where first linked MIFARE application (TK1-A) has been stored, and repeating the steps of storing linked MIFARE applications and writing link information (LK) until the last linked MIFARE application (TK1-C) has been stored.

7. A MIFARE memory device being configured as a MIFARE Classic card or an emulated MIFARE Classic memory, comprising in each of its sectors link information memory locations dedicated to being written with link information that indicates another sector where a linked MIFARE application is installed.
-
8. A trusted service manager being configured to transmit linked MIFARE applications and link information values via an Over-The-Air interface to a mobile communication device that is equipped with a MIFARE memory being configured as a MIFARE Classic card or an emulated MIFARE Classic memory, wherein the trusted service manager is adapted to instruct the mobile communication device on basis of the transmitted linked MIFARE applications and link information values to store the first linked MIFARE application in a first free sector of the MIFARE memory, to store the second linked MIFARE application in a second free sector of the MIFARE memory and to write link information indicating this second sector in a link information memory location of the sector where first linked MIFARE application has been stored, and to repeat the steps of storing linked MIFARE applications and writing link information until the last linked MIFARE application has been stored.
-
9. A reader device for retrieving MIFARE applications from a MIFARE memory that is configured as a MIFARE Classic card or an emulated MIFARE Classic memory, wherein the reader is configured to read a first MIFARE application from a first sector of the MIFARE memory, which first sector is optionally a predefined sector, reading link information from the same sector, if the link information points to another sector of the MIFARE memory reading the MIFARE application being stored in this another sector, and repeating the steps of reading MIFARE applications and link information until the link information points to an empty or invalid sector or contains a stop instruction or points to a sector that has already been read.
