Mathematics of cryptography,
in this course we will learn about the mathematical foundations that secure modern communication systems. From number theory and modular arithmetic to group theory and elliptic curves, this course dives deep into how mathematics forms the backbone of cryptographic algorithms like RSA, Diffie-Hellman, and ECC. You'll explore key techniques such as modular exponentiation, the Chinese Remainder Theorem, and discrete logarithms. The course also covers how randomness, probability, and complexity theory play a role in encryption and decryption processes. Whether you are interested in classic cryptographic methods or post-quantum algorithms, this course provides a comprehensive overview of the math behind securing data. By the end, you’ll be equipped to understand, analyze, and apply cryptographic systems using rigorous mathematical concepts. Let’s begin unlocking the science behind secure information. Zach Star
