Cryptography from Fachbereich Informatik

This lecture deals with the following cryptographic topics:

  • Cryptographic Foundations (security goals, historical ciphers, AES, a sketch of RSA)
  • Foundations of information theory (terms, probability theory, Shannon’s theorem)
  • Entropy
  • Design principles of cryptographic hash functions
  • Pseudo random number generators and stream ciphers
  • A sketch of elliptic curve cryptography
  • Quantum cryptography
  • Implementation issues (efficiency, obfuscation)
