- a user of a mobile terminal type mobile phone is faced with an increasingly rich service offer.
- a range of diverse and varied services such as payment and transport services are offered to the user. These services are accessible either locally or via a mobile phone network (GSM, GPRS %) or even in a proximity situation, for example via dialogue protocols such as Bluetooth, RFID, etc.
- US 7,263,383 discloses a method for increasing the memory size of an address book stored on a SIM card of a mobile terminal equipped with a flash memory card.
- some of the information is stored on the SIM card and additional information is stored in The flash memory in association with an identification number of the SIM.
- the mobile terminal finds the record corresponding to that recorded on the SIM card after reading the identification number in the SIM card. This method can not work if the application is installed on the SIM card because the SIM card has no means to manage resources that are not unique to it.
- the present invention improves the situation.
- the present invention proposes a memory allocation method associated with an application stored in a security module associated with a terminal, characterized in that it comprises: a step of receiving a request for allocation of memory external to the security module from said application,
- a step of storing the memory allocation information received in association with an identifier of said application a step of storing the memory allocation information received in association with an identifier of said application.

- the allocation control comprises at least one access characteristic and the memory allocation information is determined according to said at least one characteristic.
- An access characteristic is, for example, information relating to the latency (or access time) of the memory. If the application or the security module requires the shortest possible access time, the terminal will if possible choose an internal memory zone to the terminal rather than a memory zone on a remote server. Another access characteristic is, for example, information relating to the volatility of the memory. Thus, the terminal can select a volatile memory zone, for example in RAM, to store temporary application data or on the contrary a memory zone in EEPROM if the data must be kept.
- the allocation method further comprises a step of determining at least one security parameter and a step of storing said at least one security parameter in association with the application identifier.
- a security parameter is for example an encryption key to ensure the confidentiality of data during their transfer and storage outside the security module.
- Another security parameter is for example a key used for the signature of the data and thus to control their integrity.
- the security parameter (s) are generated and stored by the security module. The fact that these keys are known only to the security module makes it possible to reinforce the security of the system and to guarantee a level of data security identical to that obtained if they were stored in an internal memory of the security module.
- the invention also relates to a method for managing data associated with an application stored on a security module associated with a terminal, characterized in that memory allocation information is stored in association with an identifier of said application, the method comprises the following steps: receiving a read or write request from an external memory, said request comprising the application identifier,
- an application having reserved an external memory zone to the security module can access this memory to store and read application data. It thus has an additional memory zone.
- the step of determining a write command comprises a step of applying said at least one security parameter to data to write.
- One or more security parameters which are for example secret keys, generated and stored during the prior allocation phase, are then used to ensure the security of the data stored outside the security module.
- the method further comprises a step of applying said at least one security parameter to read data.
- one or more security settings applied to the data read from an external memory before any use by the application ensures the security of the data.
- this key can then be used to encrypt the data before transmission of these data out of the security module. to the allocated memory.
- This key will also be used by the security module to decrypt the encrypted data read in the external memory. Storing the data in an encrypted way helps to ensure the confidentiality of the data.
- the invention also relates to a terminal comprising means for receiving a memory allocation command from the security module, means for allocating a memory area according to the received allocation command, means for determining a memory allocation information relative to said allocated area, means for transmitting said allocation information memory, means for receiving a read or write command in said allocated memory area, means for accessing said allocated area and data transmission means read in said allocated area.
- the allocation means are able to determine a memory area according to at least one access characteristic contained in the allocation command received.
- the terminal when it has several types of memory, it can select the most appropriate memory according to one or more criteria provided by the security module and / or by the application.
- the at least one access characteristic relates to the speed of access to the memory.

- the latency characteristic P2 is set to 0 if the latency characteristic P2 is set to 0 if the latency characteristic P2 is set to 0 if the latency characteristic P2 is set to 0 if the latency characteristic P2 is set to 0 if the latency characteristic P2 is set to 0 if the latency characteristic P2 is set to 0 if the latency characteristic P2 is set to 0 if the latency characteristic P2 is set to 0, this means that the memory access time must be as short as possible. In this case, the memory M1 is preferentially chosen to the memory M3. On the other hand, the remote memory M3 is chosen if there is not enough space available in the memories M1 and M2.
- the management module SM2 stores in a management table TM2 of the terminal T2, a zone start address AD3 ZM2, which represents a memory allocation information AL2, and an end address AD4.

- ZM2 received in response to the allocation request RA2.
- the request RW2 is received by the control module SC2 during a step E242.
- control module SC2 verifies that the application AP2 is registered by searching for the application identifier IA2 in the correspondence table TC2 and that a memory area has been allocated for this application.
- control module SC2 can not process the received request. It then returns to the AP2 application an error message. As an alternative, he does not answer. If a memory area has been allocated, the control module SC2 then verifies that the ADW address contained in the request corresponds to the address of a record accessible by the application AP2 by using the stored AL2 memory allocation information. in the table TC2 in association with the application identifier IA2 of the application AP2.

- the write command CW2 is transmitted to the management module SM2 of the terminal T2 which receives it during a step E254.
- Step E254 is followed by step E256 in which the management module
- SM2 verifies in the management table TM2 of the terminal T2 that the area requested for writing is reserved for the application AP2. Then, if this is the case, it controls the writing of the encrypted data DCW and the signature SW in the zone ZM2 to the address ADW (step E258).
- step E258 is followed by a step E260 during which the management module SM2 sends back to the control module SC2 ACK information relating to the execution of the command CW2.
- the ACK information is then transmitted by the management module SC2 to the application AP2 (step E262).
