Modern cryptography isn't just about scrambled letters; it is built on and Abstract Algebra .
One of the most exciting areas is using coding theory to build cryptographic systems. Introduction to Cryptography with Coding Theory
: Adding extra "check bits" to a message so the original can be reconstructed even if parts are lost. The Intersection: Code-Based Cryptography Modern cryptography isn't just about scrambled letters; it
: Large primes are the bedrock of RSA encryption. Introduction to Cryptography with Coding Theory
: A method for two parties to generate a shared secret over an insecure channel.
: A public-key system based on the hardness of decoding a general linear code.
