Abstract
In a method for cryptographic code management between a first computer unit and a second computer unit, the method is divided into individual modular phases. Authentification references that are employed in further cryptographic phases are exchanged during an authentification of the first computer unit and the second computer unit. As a result thereof and due to the modular structure, a respectively new authentification actually required in the further cryptographic phases is no longer necessary and is also not implemented.
