Abstract:
The invention is a method for managing communication between a secure element and a device. The secure element comprises a physical communication interface and first and second virtual profiles. It is configured to exchange data targeting the virtual profiles with the device through the physical communication interface. The method comprises the steps of: running simultaneously said first and second virtual profiles, demultiplex incoming data received through the physical communication interface and multiplex outgoing data sent through the physical communication interface, resetting one of said virtual profiles individually without affecting the other virtual profiles in response to receiving a specific signal sent by the device through the physical communication interface.
Abstract:
The present invention relates to a method to build a non-alterable structure and to such a non-alterable structure including data relative to a set of cryptographic material generated randomly or derived from a secret key linked to a business use, the non-alterable structure being intended to be transferred from a first entity to a second entity, the entities sharing at least an encryption/decryption key and a signature key, the structure comprising at least business data relative to the intended use of cryptographic material, an encrypted protection key encrypted with the encryption key, an encrypted set of cryptographic material encrypted with the protection key, a signature of the set of cryptographic material, the protection key and the data relative to the intended use of cryptographic material signed with the signature key.
Abstract:
The invention relates to a method of communicating data with an electronic device, comprising the step of receiving signals conveyed by an electrical lead. The method is distinguished in that it comprises the following steps: fitting an RF radiofrequency interface with electrical terminals in the device, extracting signals from the electrical lead, and injecting signals resulting from the extracted signals, in the form of frames of radiofrequency signals in the RF interface with electrical terminals. The invention also relates to a radiofrequency communication device, a system comprising the device and a machine using the device.
Abstract:
The invention relates to a method for fabricating an electronic device comprising an electronic/electrical circuit, wherein it comprises the following steps: formation of a support-body comprising a battery inside; making of a cavity emerging on the surface of the support-body, said cavity revealing connection terminals of the battery; connection of an electronic/electrical circuit to the battery via the terminals situated in said cavity; exchanging of data in the electronic/electrical circuit by electrical contact. The invention also relates to the corresponding electronic device.
Abstract:
The invention relates to a method for carrying out an electronic transaction between a main communication apparatus and a transaction terminal, wherein a smart portable accessory is provided, which has a different format from a standardized chip card format and is capable of relaying the transaction or of representing said main apparatus relative to a transaction terminal; and the transaction is carried out by only presenting said accessory, instead of the main apparatus, to the transaction terminal. The invention also relates to the corresponding system.
Abstract:
The invention relates to an electronic module comprising a dielectric support film having a first side, conductor paths that are printed on said first side, and a semiconductor component which connects the conductor paths by means of electrical connections. The electronic module of the invention is characterized in that each electrical connection includes a lead wire that connects a contact of the semiconductor component to each path directly or via an island or an interconnection pad.
Abstract:
To a method for accessing a service, at least one first user device executes a first application that communicates with a second user device application. The first user device sends to a remote server data relating to the first application execution, as a first user device report. The data relating to the first application execution includes information relating to either an incoming event or an outgoing event and at least one attribute relating to the first application execution. The remote server determines, based upon at least the first user device report, a trust level relating to the first user device. A third user device sends to the remote server a request for getting a trust level relating to the first user device. The remote server sends to the third user device, as a request response, the trust level relating to the first user device.
Abstract:
The present invention relates to a system and method for securing offline usage of a certificate by authenticating a user by a One Time Password (OTP) system when the user computing device is working in offline. An external authentication server of the server generates a set of expected OTP to protect the certificate. The server encrypts each certificate with a wrapper key and derivates a key from each OTP. Each derived key encrypts the wrapper key to create a set of encrypted wrapper keys. The computing device stores into its memory the encrypted certificate and the set of encrypted wrapper keys received from the authentication server. During a use of the certificate by the computing device working offline, an authentication request is received from a user of the computing device, the authentication request including a user-provided OTP. The computing device derives a key from the OTP provided. The OTP derived key being used to decrypt one corresponding wrapper key of the set of encrypted wrapper keys. The decrypted wrapper key being used to decrypt the certificate
Abstract:
This invention relates to a method used by an authorized user for the verification of a document having electronic verification means, The method comprises the various steps consisting in:—reading, with electronic reading equipment with which the authorized user is equipped, of information stored in the electronic verification means of the verified document;—transferring verification information, established on the basis of the information saved in the electronic verification means, from the electronic reading equipment to a viewing device of the authorized user, which viewing device is positioned, in normal conditions of use, in front of the eyes of the authorized user, the said viewing device being transparent to allow the said authorized user to see through it.
Abstract:
The invention relates to a method for loading at least one native code on at least one target secure element comprising a java card virtual machine, said method comprising the following steps: providing a modified CAP file composed of at least one custom CAP component comprising a native code; extracting said native code from the custom CAP component; installing said native code in the target secure.
