Abstract: 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.

Abstract: An electronic device includes a secure element and an application programming interface. The secure element, in operation, executes a first application. The application programming interface, in operation, verifies a reliability of a received command directed to the first application, and transmits the command and a result of the verification to the first application.

Abstract: 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.

Abstract: An NFC device may include a first and second controller interfaces, a first communication channel coupled to the first controller interface, and a second communication channel connected to the second controller interface. A secure element may include a secure element interface connected to the first communication channel and encryption/decryption circuitry configured to encrypt data to be sent on the first communication channel for being framed into the encrypted frames and to decrypt encrypted data extracted from the encrypted frames and received from the first communication channel. The secure element may also include management circuitry configured to control the encryption/decryption circuitry for managing the encrypted communication with the NFC controller. A device host may include a host device interface coupled to the second controller interface and control means or circuitry configured to control the management circuitry through non-encrypted commands exchanged on the first and second communication channels.

Abstract: 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.

Abstract: 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.

Abstract: A method is for managing information communication between an NFC controller coupled to an antenna for a contactless communication with an object, a device host, and a secure element. The method may include routing the information through the NFC controller, and communicating first information to be communicated between the secure element and the device host through a first communication link between the NFC controller and the device host, and through a second communication link between the NFC controller and the secure element. The method may include communicating second information with the antenna through a third communication link between the NFC controller and the secure element, the first and second communication links having bandwidths greater than a bandwidth of the third communication link.
