Abstract: The services of an HTTP or HTTPS server, being implemented by or running on a first electronic device that is a portable device, are offered to an application running on a second electronic device by exchanging HTTP messages between the first electronic device and the second electronic device over a local communication channel according to the Bearer Independent Protocol. The application running on the second electronic device may use the TCP/IP protocol for exchanging HTTP messages with the server. A gateway is employed on the second electronic device, which manages the local communication channel and performs protocol conversion, Bearer Independent Protocol—TCP/IP, for messages received from the application running on the second electronic device, and protocol conversion, TCP/IP—Bearer Independent Protocol, for messages being sent to the server, where the second electronic device is a terminal hosting the portable device.

Abstract: The solution concerns the access to a number of data files stored in the memory of a data processing device. The device includes a privilege file (P1-P3) associated with a user type (ADM, PUBLIC, USER1, USER2), the privilege file identifying for at least one command (SEL, INS, UPD, SUP) the data files on which the command can be executed. A microcontroller is programmed to create, when a user accesses the data files, a set of flags from the privilege file, each flag being associated with a unique data file, the flag indicating whether or not the command can be executed on the associated file.

Abstract: Method for monitoring the usage of a service by a communication device coupled to a tamper resistant module, in particular a smart card. A said service is transmitted from a resource able to communicate with said communication device by way of a network. The service comprises a plurality of encrypted data flow and its use comprises successive decryption steps of data flow by a respective first key EK, said first key EK being encrypted in the data flow and decrypted in the tamper resistant module by way of a second key KEK stored in said tamper resistant module or derived inside said module. The invention is characterized in that said method comprises the following steps: a. A counting step, in which a memory location stores a count of occurrences of decryption steps of said first key EK attached to a same service; b. A using step, in which said counter is used to prove the amount of data flow which has been decrypted.

Abstract: 1) A method for synchronizing databases (DB1, DB2), a first database (DB1) being stored in a first data processing system (MOB), a second database (DB2) being stored in a second data processing system (MNO), said method comprising: a. A loading step in which an application (APP) is loaded into said first data processing system (MOB); b. An execution step in which the application (APP) executes a command; c. A requesting step in which said command requests the first data processing system (MOB) to process a synchronization step, said command providing the first data processing system (MOB) with the information about the synchronization parameters to be used for synchronizing the content of the first (DB1) and the second (DB2) databases, said method being characterized in that said first data processing system (MOB) includes a security token (CAR) controlled by an operator (OP) and in that said application (APP) is loaded into said security token (CAR).

Abstract: The solution concerns a method to query a relational database stored on a computer comprising a microcontroller, said database comprising at least a table composed of columns and rows including data accessible via a cursor. The method includes the following steps: Before executing the cursor, declare a cursor by systematically selecting all columns in the table concerned by the cursor, execute the cursor, after execution, select columns using a SEARCH command capable of selecting columns in the cursor result.
