Overview

Cryptography is a vital component of modern electronic security technologies.

Aims

The course aims to give students a good appreciation of cryptographic techniques, as they have arisen historically, and as they are used today.

Learning outcomes

  • ​​​​​​Comment on the broad principles underlying cryptography and its applications.
  • Describe some of the classical cryptographic techniques and their weaknesses.
  • Describe the principles of the most widely used private key cryptographic schemes.
  • Describe the principles of the most widely used public key key cryptographic schemes.

Syllabus

  • Early cryptography: permutations and substitutions, Vignere, Vernam, one time pads, etc.
