These diagrams have been created in the winter term 2020/2021 at Kiel University during a cryptography lecture for computing education students. Some of the following image were only used to illustrate specific examples and might not be suitable for Wikimedia Commons. I hope that this only applies to a minimal portion of the images.

Digital signatures

• 
  The algorithms involved in an asymmetric cryptographic signature process
• 
  An attacker on a digital signature algorithm
• 
  An attacker ${\displaystyle A}$ for a digital signature cryptosystem is created by reduction from another attacker ${\displaystyle A'}$.

Message authentication codes

• 
  The algorithms involved in generating and validating message authentication codes.
• 
  An attacker on a MAC algorithm
• 
  A cascading algorithm to create message authentication codes
