Entrance requirements:
For graduate students: Basic knowledge in theoretical computer science required, background knowledge in number theory and complexity theory helpful

Aims / Competences to be developed:
The students will acquire a comprehensive knowledge of the basic concepts of cryptography and formal definitions. They will be able to prove the security of basic techniques.

Content:

  • Symmetric and asymmetric encryption
  • Digital signatures and message authentication codes
  • Information theoretic and complexity theoretic definitions of security, cryptographic reduction proofs
  • Cryptographic models, e.g. random oracle model
  • Cryptographic primitives, e.g. trapdoor-one-way functions, pseudo random generators, etc.
  • Cryptography in practice (standards, products)
  • Selected topics from current research


Assessment / Exams:

  • Oral / written exam (depending on the number of students)


A re-exam is normally provided (as written or oral examination)


Used Media:
