CYBS4250 - Data Security & Cryptography

Today, cryptography is everywhere! This course introduces modern applied cryptography by learning about how crypto schemes work and how they can be used in practice to secure data both at rest and in motion. It explains not only how cryptographic primitives work but also how to use them correctly and reason about security. It covers modern crypto schemes of practical relevance, including the Advanced Encryption Standard (AES), Data Encryption Standard (DES) and 3DES, RSA cryptosystem, elliptic-curve cryptography (ECC), Diffie-Hellman key exchange, digital signatures, and the SHA hash function family. Protocols and key establishment methods, including certificates and public-key infrastructure, are also introduced. This course focuses on cryptographic algorithms and their minimum mathematical background to better understand the essentials.
