Aim and Content

The course is an extension of the theory of cryptology given in INF240. The course deals with the construction of and the attack on some cryptographic ciphers, cryptographic hash functions, and digital signatures.

We will also look at other topics within cryptology- the selection will vary from time to time. Examples of such topics are authentication codes, elliptic curve cryptography, secret sharing systems, zero-knowledge proofs, random number generators, secure multicasting, and information theoretical tools.

Learning Outcomes

After completing the course the student should be able to

  • Explain the mathematical foundation for and construction of central ciphers, hash functions, and digital signatures.
  • Implement standard cryptographic systems.
  • Digest and explain cryptographic algorithms.
