Abstract
There is provided mechanisms for generating a cryptographic key for a user. The method is performed by a cryptographic key generator device. The method comprises authenticating the user using biometrics data read from the user using a biometrics reader. The method comprises obtaining, only when having authenticated the user, a PUF response from a PUF entity by providing a challenge based on biometrics response data to the PUF entity. The biometrics response data is a function of the biometrics data. The method comprises generating the cryptographic key using a cryptographic function and by seeding the cryptographic function with the PUF response.
