Abstract
The invention relates to a method of executing a secure application in an NFC device, the method comprising steps during which: a contactless link is established between first and second NFC devices, the first NFC device transmits by the contactless link an identifier of a secure processor of the first NFC device, the second NFC device transmits by the contactless link an application identifier, the secure processor transmits by the contactless link first authentication data allowing the authentication of the secure processor of the first NFC device, the second NFC device transmits to an application server the first authentication data, the application server transmits to an authentication server the first authentication data and second authentication data) to authenticate the application and authorizes the two NFC devices to execute the application only if the secure processor and the application are authenticated.
