Cryptography – Number Theory Prerequisites

[Stub] Short mathematical warm-up for modular arithmetic, gcd, and related concepts that appear in later cryptographic constructions.

Topics

  • Modular arithmetic and congruences
  • Greatest common divisor and Euclid’s algorithm
  • Modular inverses (conceptual)
  • How these tools show up in cryptographic schemes

Reading and Preparation

[Stub] Reference the Canvas module or textbook sections on number theory for cryptography.
