Introduction - To Cryptography With Coding Theory

: A method for two parties to generate a shared secret over an insecure channel.

This uses a pair of keys: a (shared with everyone) and a Private Key (kept secret).

Modern cryptography isn't just about scrambled letters; it is built on and Abstract Algebra . Introduction to Cryptography with Coding Theory

: Relies on the difficulty of factoring the product of two large prime numbers.

: The "clock math" that forms the basis of many ciphers. : A method for two parties to generate

: The "Key Exchange" problem—how do you share the key securely? 2. Asymmetric (Public-Key) Cryptography

: Extremely fast and efficient for large amounts of data. Introduction to Cryptography with Coding Theory

: Large primes are the bedrock of RSA encryption.
