Abstract: The present invention concerns a method of radio-frequency communication between a contactless transponder and a reader, in which at least one sideband of the carrier frequency is used for communicating a response from the transponder by modulation of the amplitude of this carrier frequency. The method is distinguished in that the modulation at least partly applies a modulation level greater than 100%, which causes a negative modulation. The invention also concerns a corresponding communication circuit.

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 for managing an application that includes a generic part and an additional part. The generic part is pre-installed on a device. The device gets a fingerprint of itself and after a user authentication sends to a server a request for getting the additional part. The request comprises credentials associated with the user or a reference of the user, the fingerprint and a reference of the application. The server generates a ciphered part of the additional part using a key based on both the credentials and the fingerprint and builds an auto-decrypt program configured to decipher the ciphered part. The device receives the ciphered part and the auto-decrypt program. It gets the fingerprint and the credentials and retrieves the additional part by running the auto-decrypt program with said fingerprint and credentials as input parameters.

An application is installed in the secure element and configured to be implicitly selected on the communication interface. The method comprises the following steps: —the secure element receives a command requesting the installation of a new application configured to be implicitly selected on the communication interface, —upon receipt of the command, the secure element installs the new application, configures the new application to be implicitly selected on the communication interface and keeps the previous application unchanged.

Abstract: A method, a device and a system for printing a three dimensional object are disclosed. A printing device, as a first device, or a second device stores predetermined data relating to one or several printings. The second device cooperates with the first device. The first or the second device stores a predetermined printing threshold. The first or the second device determines and stores, during a printing of the three dimensional object, at least one current printing progress rate. The first or the second device compares the current printing progress rate to the predetermined printing threshold. As soon as the current printing progress rate is greater than or equal to the predetermined printing threshold, the first or the second device updates the data relating to one or several printings, so as to validate the printing of the three dimensional object.

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: A requester device sends to a server a request for proving a piece of user information and data identifying a requester. The server generates requester authentication data and associated data identifying a transaction. The server generates a proof of user information using the piece of user information and the requester authentication data. The server sends to the requester device, as a request response, the proof of user information and the associated data identifying the transaction. A verifier device sends to the server a request for getting authentication data associated with data identifying a transaction and the associated data identifying the transaction. The server sends to the verifier device, as a request response, authentication data associated with the data identifying the transaction. The verifier device or a verifier authenticates the piece of user information only if the received authentication data matches the requester authentication data.

When an authentication is required in a given local network (LNj), an UICC application derives a local key (LKiLNj) in the UICC application of the subscriber (IMSIi) using the network identifier (LNj), the key derivation function (KDF) and the subscriber key (SMKi) and use the derived local key (LKiLNj) in the algorithm to perform local authentication in the local network (LNj).

Abstract: The invention is a method for deploying a trusted identity for a user issued by an issuer. The user has a user device configured to send a request for signature to an issuer device handled by the issuer. The request comprises a user public key allocated to the user. The issuer device is configured to compute an issuer signature by signing both the user's trusted identity and the user public key using an issuer private key allocated to the issuer. A block chain transaction containing the issuer signature is created and submitted to a Block Chain for transaction verification and storage.

Abstract: A chip is coupled to a device. The device stores at least one configuration parameter for configuring an access to an Internet type network. According to the invention, the chip stores data relating to at least two subscriptions. The method comprises the following steps. The chip de-activates a first subscription. The chip activates a second subscription. The second subscription is distinct from the first subscription, as a previously active subscription. The second subscription is a currently active subscription. The chip detects whether the device does or does not read a currently active subscription. Only if the device reads a currently active subscription, then the chip detects whether at least one configuration parameter does or does not allow accessing an Internet type network. Only if at least one configuration parameter does not allow accessing an Internet type network, then the chip ascertains that at least one configuration parameter is corrupted.
