Abstract

In a method for cryptographically processing data which are exchanged between a first unit and a control unit, a derived key is used in this process, which is derived from a secret key and an identifier. The exchanged data are encrypted using the derived key, and the exchanged data are encrypted in a tool chain, which provides the identifier.
