Schlüsselaustauschmodells
The Schlüsselaustauschmodell, or Key Exchange Model, is a conceptual framework used in cryptography and network security to describe how cryptographic keys are securely shared between parties. It outlines the necessary steps and protocols to ensure that only authorized individuals can access or use these keys. The core challenge addressed by such models is the "key distribution problem" – how to get a secret key to two or more parties without an eavesdropper intercepting it. Different Schlüsselaustauschmodelle exist, each with its own strengths and weaknesses, depending on the specific security requirements and the underlying cryptographic primitives employed.
Common approaches within Schlüsselaustauschmodelle include pre-shared keys, where keys are manually exchanged beforehand, and dynamic key
