    Abstract: The invention relates to a method of reading RF transponders disposed in one and the same magnetic interrogation field, in which a magnetic coupling of the transponders is ensured with a passive resonant circuit during reading. The method is distinguished in that the passive antenna of the resonant circuit is associated with at least one transponder antenna, and the passive resonant circuit is tuned in such a way that the resonant frequency resulting from the association corresponds to one of the frequencies of the emission side bands of the transponder to be read. The invention also relates to the system corresponding to the method, a transponder structure and an object containing the transponder, in particular a travel document.

    Abstract: The invention is a method of updating a first executable code comprised in a first package in a secure element, a class instance being instantiated from said first package and comprising instance data. The method comprises the following steps: loading in the secure element an upgrade file comprising a second executable code and creating a second package from said upgrade file, changing said first executable code for said second executable code by replacing a reference to the first package by a reference to the second package in a package list stored in the secure element, while leaving the class instance alive and said instance data unchanged.

    Abstract: The invention relates to a random clock generator comprising an input receiving a master clock signal MCIk, and a clock signal reduction circuit (101) receiving the master clock signal MCIk and a whole number N and supplying an output signal corresponding to a train of N pulses every M clock pulse, M being a whole number higher than 1 and N being a whole number higher than 1 and lower than or equal to M. A number generator (102) and (103) supplies a new number (N) to the clock signal reduction circuit every P pulse of a master clock signal, N and/or P being produced randomly.

    Abstract: The present invention relates to a secure platform implementing dynamic countermeasures in relation with the execution of a code, said secure platform having at least a security sensor, a countermeasure controller and countermeasure means. According to the invention, said countermeasure controller includes at least one security sensor flag able to take at least two sensor flag values depending on the output of the security sensor, a table storing N possible security configuration for the countermeasures, a random generator to generate a random configuration value, a decision function using the sensor flag value and the random configuration value to determine a security configuration in the table to be executed by countermeasure means.

    Abstract: A device comprises a memory. The memory stores data relating to at least one service profile template. The service profile template includes executable data. A server sends to the device a first message including a request for creating or modifying at least one service profile based upon a service profile template. The device executes the executable data. The device creates or modifies a memory area. The memory area is associated with a service profile by using the service profile template. The device sends to the server at least one second message including a request for loading into the device data relating to at least one service profile. The server sends to the device at least one third message including data relating to at least one service profile. And the device stores within the created or modified memory area the data relating to at least one service profile.
