Abstract
The invention relates to a method for authenticating to a device, comprising receiving, by the device, from a chip, data; retrieving, by the device, based on the received data, a predetermined encrypted credential; sending, by the device, to the chip, a decryption request for decrypting the encrypted credential including or being accompanied with the encrypted credential to be decrypted; retrieving, by the chip, a secret key; decrypting, by the chip, the encrypted credential by using the secret key; sending, by the chip, to the device, as a decryption request response, the credential; verifying, by the device, whether the credential is or is not valid; and authenticating, by the device, only if the credential is valid, the chip.
