Patent ID: 8850527

Claim:
A method of executing a secure application in a Near Field Communication (NFC) device, the method comprising: establishing a contactless link between a first NFC device and a second NFC device, the first NFC device comprising a secure processor, transmitting a secure processor identifier identifying the secure processor of the first NFC device from the first NFC device to the second NFC device over the contactless link, transmitting an application identifier from the second NFC device to the first NFC device over the contactless link, transmitting secure processor authentication data for authenticating the secure processor of the first NFC device, from the secure processor to the second NFC device over the contactless link, transmitting the secure processor authentication data from the second NFC device to an application server, transmitting the secure processor authentication data and application authentication data for authenticating an application corresponding to the application identifier, from the application server to an authentication server, and in the authentication server, verifying the secure processor authentication data and the application authentication data and authorizing the first and second NFC devices to execute the application only if the secure processor and the application are authenticated by way of the secure processor authentication data and the application authentication data.
