Oberthur Technologies | Date: 2017-03-22

A method of communicating between a terminal (20) and a secure element (10) comprises determining a challenge and sending the challenge (122) to the terminal (20). The secure element receives a response (124, 126) from the terminal (20) comprising the challenge and personal identification number, PIN, data. The response is encrypted with a key. The secure element determines (132) if the challenge received in the response matches the challenge sent to the terminal (20). If the challenge received in the response does not match the challenge sent to the terminal (20), the secure element performs a computation (133) using the received challenge and the sent challenge. The secure element recovers a data element (136) carried by the response. The data element (136) is indicative of an action to be performed by the secure element. The data element can be an encrypted operation code.

A secure element (10) performs (40) a secure transaction by communicating with an external terminal (20). The transaction comprises a plurality of events when the secure element receives a command message from the external terminal and sends, in reply, a response message to the external terminal. During the secure transaction the secure element (10) determines (43) a time interval between sending a response message to the external terminal (20) and receiving a subsequent command message from the external terminal (20) and stores (47) log data indicative of the determined time interval at the secure element (10). The secure element (10) may send the stored log data to the external terminal (20) or perform (48) a security action at the secure element based on the log data. An external entity, such as an authorisation entity (30), may receive the log data and perform a security action based on analysis of the log data.

The invention relates to a method for generating a session key (SK) for a secure data exchange between a first electronic entity (H) and a second electronic entity (C), characterised by the following steps: determining (E2), by means of the first electronic entity (H), a first verification word (PRM); transmitting (E4) the first verification word (PRM) from the first electronic entity (H) to the second electronic entity (C); incrementing (E14) a counter (SQC), by means of the second electronic entity (C), only when the first verification word (PRM) is identical to a second verification word (PRM*); generating (E18) a session key (SK), by means of the electronic entity (C), on the basis of the value of the counter (SQC). The invention also provides an electronic entity (C) designed such as to exchange data with another electronic entity (H).

The invention relates to a method implemented by a profile management server (500) for managing the profiles (P1, P2, PROV) of a secure entity. Said method comprises: a step (S25) of sending a message (302) to said secure entity in order to modify the active profile of said entity; a step (V50) of initialising and initiating a time-recording meter (TIM); and in the event that said server (500) does not receive a message indicating the active profile in said secure entity (100) before the expiry of a predetermined period starting from said initiation: a step of initiating an audit procedure (V100) in order to determine the effectively active profile in said secure entity (100).

Devices and methods for masking and unmasking sensitive data, based on a standard cryptographic algorithm defining a ciphering algorithm, and a deciphering algorithm using more resources than the ciphering algorithm are described. The masking of sensitive data is done by applying the deciphering algorithm to the sensitive data to obtain masked sensitive data. The unmasking of the masked sensitive data is done by applying the ciphering algorithm to the masked sensitive data to obtain sensitive data in plain form.


The invention relates to a method for treating a faulty connection to a telecommunications network (N), comprising the following steps: - establishing a secure link (SL) between a first terminal (B), storing a first access profile (PB) for access to the telecommunications network (N), and a second terminal (A), storing a second access profile (PA) for access to the communication network (N) associated with the faulty connection; - communicating, from the second terminal (A) to the first terminal (B), via the secure link (SL), data relating to the second profile (PA); - transmitting, by the first terminal (B), using the first profile (PB), data relating to the second profile (PA) to an infrastructure server (SMB) of the telecommunications network (N).

The invention relates to a bank card (100) comprising a presentation surface of a pictogram (120) coding at least one item of information for executing a transaction.


The invention relates to an electronic device comprising a microprocessor (16), a body (14) defined by at least first and second opposite surfaces, a battery (32) arranged inside the body (14), an electronic component electrically connected to the microprocessor (16) and to the battery (32). The electronic device has at least one cavity (38) comprising an opening leading to one of the surfaces of the body (14) and in which the electronic component is attached. The electronic component comprises an information display area positioned relative to the opening of the cavity (38). The device further comprises at least a first module (20) comprising a substrate (22) for covering the cavity (38) such as to be flush with the first surface of the body (14). The substrate (22) of the module (20) is made of a transparent material and covered with a printed pattern defining a visual-access window (26) opposite the display area of the electronic component.

The invention relates to a method for administering life cycles of communication profiles managed by a subscriber identity module (100) installed in a telecommunications terminal (110), the method being implemented by the module (100), the module (100) being capable of using at least one administration method, the method using a set of at least one command and/or at least one rule, the method comprising the steps of: - receiving (B610) a message (M610) transmitted by the terminal (110) and representative of the capacities of the terminal (110), - selecting or not selecting (B615) the set used by the method, depending on the capacities of the terminal (110), and - if the set is selected, administering at least one life cycle of at least one of the profiles by using the set of at least one command and/or at least one rule.


The invention relates to an electronic document comprising a body (12) including a cavity (24) open on one the surfaces of the body (12) and defined by walls, said body (12) further comprising an antenna (36) which comprises at least one turn (36c) extending between two ends (36a, 36b) that lead to a wall of the cavity (24), a module (14) comprising a microprocessor (16) and at least two connection terminals (20a, 20b) for the antenna (36) and connected electronically to the microprocessor (16) and to the ends (36a, 36b) of the antenna (36) via electrical connection means. The ends (36a, 36b) of the antenna are arranged in a zigzag pattern and are composed of at least two straight portions (42) connected to each other by a bend (44), the straight portion (42) which leads to the cavity being angled relative to the wall at which it terminates.
