An electronic device includes a processor and one or more secure elements. The processor executes a first high-level operating system and a first application. The one or more secure elements execute a first low-level operating system to verify a reliability, an authenticity, or a reliability and an authenticity of the first high-level operating system, and execute a second low-level operating system to execute a second application and to perform wireless communication with the first application. At each booting of the electronic device, the first low-level operating system performs a verification of the reliability, of the authenticity, or of the reliability and the authenticity of the first high-level operating system. In response to a request from the first application to the second application, the second low-level operating system requests a result of the verification from the first low-level operating system, and transmits the result to the second application.

Protection of an electronic device

In an embodiment a method for implementing a NFC transaction between a mobile terminal and a distant module is disclosed. The terminal includes a processor hosting an application configured to establish the NFC transaction and an interface software configured to execute instructions of the application, a near-field communication module and a secure element distinct from the processor. The method includes requesting, by the application via the interface software, which verifies whether the application is authorized to communicate with the secure element, authorization to implement the NFC transaction from the secure element, sending, by the secure element, a first temporary authorization to the interface software, verifying, by the interface software, at least for a first time when the near-field communication module receives first data from the distant module, whether the interface software has received the first temporary authorization and transmitting, by the interface software, the first data to the application when the interface software has received the first temporary authorization.

NFC transaction

In an embodiment a method for implementing a NFC transaction between a mobile terminal and a distant module is disclosed. The terminal includes a processor hosting an application configured to establish the NFC transaction, a near-field communication module, and a secure element distinct from the processor. The method includes storing, by the near-field communication module in the secure element, first data from the distant module, sending, by the near-field communication module, second data to the application notifying it that the first data have been stored in the secure element and requesting, by the application, the first data from the secure element.

Provided are techniques for protecting a transaction in near-field communication. Provided is an electronic device including a processor hosting an application, a near-field communication module, and a secure element distinct from the processor. The near-field communication module is configured to identify the type of terminal emitting a polling frame, addressed to the application, that the communication module receives by analyzing the type of the polling frame. The device is configured to compare the result of the analysis with at least one command received from the terminal during the implementation of an NFC transaction.

Protection of a transaction in near-field communications

The present description discloses a secure element and a communication method comprising at least one operating system including at least one application having a register associated therewith, a buffer memory, and a router having a software layer. The software layer is configured to directing first messages using a first protocol and intended for the application to the buffer memory, and directing second messages using a second protocol different from the first protocol and intended for the application to the register.

Secure element and method

The present description concerns a method of implementation of an NFC transaction between a mobile terminal and a distant module. The terminal includes a processor hosting an application establishing the NFC transaction, a near-field communication module, and a secure element distinct from the processor. The method includes at least the following successive steps: (a) the near-field communication module ciphers first data sent by the distant module by using a first key supplied by the secure element and (b) the first application deciphers the first data by using a second key supplied by the secure elements.

The present description discloses a secure element and a communication method comprising a router managing first messages using a first communication protocol between applications of the secure element and the outside of the secure element, and a software layer performing a processing at the level of the router. The software layer is adapted to verify the compatibility of a second communication protocol, different from the first one, with which second messages are received, in the absence of a compatibility, convert the second messages into the first communication protocol, and transmit the second messages to the router.

Secure element and method for converting message communication protocols

The present description discloses a secure element and a communication method, configured to implement at least one first application, and including a circuit configured to record routing data and a list and parameters of communication protocols compatible with the first application, verify the compatibility of a first communication protocol used by first messages intended for the first application with the protocols of the list, convert the first messages into second messages by using a second communication protocol in response to the first protocol not being compatible with at least one of the protocols of the list, and direct the second messages to the first application by using the routing data of the first application.

Secure element and method for managing message communication protocols

A method and associated circuits protect data stored in a secure data circuit of a telecommunication device equipped with a near-field communication (NFC) router, a microcontroller, and the secure data circuit. In the method, each message received with the NFC router is parsed to retrieve a communication pipe identifier and an instruction code. The communication pipe identifier and the instruction code are compared to corresponding information in a filter table. Instruction codes of particular messages that attempt to modify a communication pipe by reassigning one end of the communication pipe from the port of the NFC router to a different circuit are acted upon. These messages are blocked from reaching the secure data circuit when the instruction code is not authorized in the filter table, and these messages are permitted when the instruction code is authorized in the filter table.

Protection against rerouting a communication channel of a telecommunication device having an NFC circuit and a secure data circuit

Data exchanges between an ultra-wide band communication module and a secure element are controlled such that the data exchanges pass through a near-field communication router. The near-field communication router controls routing of the data exchanges so that the data exchanges do not pass through a host circuit that is also coupled to the near-field communication router.
