摘要
A device is provided for controlling secure transactions using a physical device held by a user and bearing at least one first pair of asymmetric keys, including a first device public key and a first corresponding device private key. The control includes, prior to implementing the device, certifying a first device public key and characteristics data of the physical device by signing with a first certification key, delivering a factory certificate, after verifying that the device private key is housed in a tamper-proof zone of the physical device. At least one second pair of asymmetric keys is generated, including a second device public key and a second device private key housed in a tamper-proof zone of the device. A second device public key is certified by signing with at least the first device private key, delivering a provisional certificate. The factory and provisional certificate are verified using, respectively, a second certification key corresponding to the first certification key, and the first device public key. In case of positive verification, the method includes delivering by a trusted third party a device certificate corresponding to the signature by the provider at least the second device public key and an identifier of the user and the characteristic data of the device.
