Embodiment Construction

[0054] Now, will refer to figure 1 with figure 2 One embodiment of a data transfer method and a method of accessing such data is described.

[0055] refer to figure 1 , the user has a mobile terminal 10 such as a cellular phone or a PDA (Personal Digital Assistant).

[0056] The mobile terminal has a communication module 30 (eg a GSM module) enabling communication via a communication network R with a remote server (eg with a management server T). This communication is, for example, "OTA" (Over-The-Air) communication, that is to say conventional wireless communication. Alternatively, the mobile terminal is linked to the network R via a wired telephone line.

[0057] The mobile terminal 10 also includes a security module 20 .

[0058] The security module 20 is, for example, a removable medium of SIM or UICC (universal integrated circuit card) type, a secure storage area of ​​a mobile terminal, or a memory card loaded with secure elements (SD card, embedded security control...

Abstract

The invention pertains to a method of transferring data related to an application installed on a security module (20) associated with a mobile terminal (10), the data being stored in a first secure memory area (C) of the security module, adapted for receiving a data access request, for reading the data, and for transmitting or storing the data after encryption. The invention also pertains to a method of accessing these data which is suitable for transmitting an access request, for receiving and for decrypting the encrypted data. The invention also concerns a security module, a management server and a system implementing the transfer and access methods.

Description

technical field [0001] The present invention relates to the field of telecommunications and, more particularly, to the field of security of applications hosted on a secure element of a mobile terminal. Background technique [0002] Most existing mobile terminals can be used not only to make telephone calls, but also to execute a certain number of applications downloaded into a security module associated with the terminal. The security module may be a memory module of the terminal or a removable medium (eg a subscriber chip card) inserted into the terminal. [0003] The downloading of these applications takes place via a regular connection between the mobile terminal and the management server. [0004] Such an application includes, on the one hand, a program part executed when an instruction for selecting an application is received from an external device item (for example, a contactless terminal), and on the other hand includes an application data area. [0005] These appl...
