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.
