What will I learn?
This Number Theory Course provides a focused journey from divisibility and modular arithmetic to RSA-style encryption, featuring clear, rigorous proofs and practical computations. You will explore primes, Euler’s totient, Euler’s theorem, key generation, encryption and decryption, security principles, and best practices, then learn to present precise calculations and results in a polished final report.
Elevify advantages
Develop skills
- Master modular arithmetic: apply congruences, inverses, and residue systems quickly.
- Handle RSA key maths: compute φ(n), d, and secure exponents using Euclidean algorithms.
- Develop prime and totient skills: utilise φ(n), λ(n), and primality tests in actual cryptography.
- Execute encryption workflow: perform RSA encoding, modular exponentiation, and decryption.
- Refine proof-writing: present neat number-theoretic arguments for crypto reports.
