Abstract
An authentication method between a secure host processor and a controller of an NFC system, the controller being equipped with an NFC interface circuit sending and receiving contactless data, includes connecting the host processor to the controller and checking that there is a predefined relation between a first secret data stored by the host processor and a second secret data stored by the controller. The method further includes transmitting the second secret data to the controller and storing of the second secret data by the controller. The host processor may be removably associated with a contactless component storing the second secret data which is contactlessly transmitted to the controller.
