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: 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.

Abstract: 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.

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.
