Cryptography

• 26 hrs lectures
• 13 hrs projects

Students will learn basic principles of applied cryptography, including classical cryptography and modern secret key and public key cryptography.

Students will learn the role of security and functionality in information systems.

The goal is to make students familiar with the basic concepts applied cryptography, including classical cryptography and modern secret key and public key cryptography.
