Abstract
A unique hardware key is recorded a secure hardware environment. A first logic circuit of the secure hardware environment is configured to generate a unique derived key from said unique hardware key and at least one piece of information. The at least one piece of information relates to one or more of an execution context and a use of a secret key. The secure hardware environment further includes a first encryption device that performs a symmetric encryption of the secret key using the unique derived key. This symmetric encryption generates an encrypted secret key for use outside of the secure hardware environment.
