SCS2206 Cryptography

A rigorous introduction to modern cryptography. Emphasis will be placed on the fundamental cryptographic primitives of public-key encryption, digital signatures, pseudo-random number generation, and basic protocols. The course will discuss both the foundations of modern cryptography in computational complexity theory and the main conceptual applications of cryptographic primitives. 

Course Objectives

• Be competent with basic cryptographic protocols such as key exchange, identification, and commitment schemes. 
• Be familiar with cryptographic hash functions, message authentication codes, and digital signatures. 
• Be familiar with mathematical foundations of cryptography and mathematical formulations of security goals.
• Be exposed to zero-knowledge proof systems. 
• Be exposed to advanced cryptographic protocols such as electronic voting and digital cash. 
• Be exposed to cryptographic attacks.

Learning Outcomes

• To provide a basic introduction to central aspects of symmetric and asymmetric cryptography. 
• To establish knowledge and understanding of how cryptographic techniques are used to establish security in modern information- and communication systems.
