Course Description

This is an introduction to cryptology with a focus on applied cryptology. It was designed to be accessible to a wide audience, and therefore does not include a rigorous mathematical foundation (this will be covered in later classes). The class format is lecture and discussion. This class covers the following at a high level:

  • Intro to cryptology, cryptography, cryptanalysis
  • Overview of cryptography
  • Symmetric cryptography
  • Asymmetric cryptography
  • Protocols
  • Overview of adversary capabilities
  • Overview of types of attacks
  • Case studies of real attacks on real systems
  • Standards

Learning Objectives

  • Understand the differences and relationships between "cryptology", "cryptography", and "cryptanalysis.”
  • Understand the role of cryptography in computer security and information assurance.
  • Understand the core concepts of cryptographic algorithms.
  • Understand classes of symmetric and asymmetric algorithms, and when each is appropriate.
  • Understand different adversarial models, relative difficulty, and how they might manifest in the real world.
  • Understand what it means for an algorithm to be "secure" and "broken."
  • Identify cryptographic standards organizations.
