Single-Course English 5 ECTS

Cryptology 1

Overall Course Objectives

The main purpose of this course is to introduce the student to central concepts and methods in cryptography.

Learning Objectives

  • Explain the pillars of modern cryptography: security definitions, security reductions, attacks
  • Describe the concept of a block cipher and how block ciphers are used
  • Analyze the security of block cipher modes of operation
  • Outline the applications of cryptographic hash functions in cryptography, and analyze and discuss their generic security
  • Discuss the differences between classical (symmetric) cryptography and public-key (asymmetrical) cryptography.
  • Describe the design of AES
  • Present the RSA public-key cryptosystem, and explain how the system is used for encryption and to construct digital signatures.
  • Discuss the quantum threat to cryptography.
  • Explain the Learning With Errors problem and Regev’s encryption scheme.

Course Content
