Mathematics And Cryptography

Summary

Today we're going to talk about how to keep information secret, and this isn't a new goal. From as early as Julius Caesar's Caesar ... Modular Arithmetic is a fundamental component of Eddie Woo demonstrates the RSA encryption process by walking through a simple numerical example to convert a letter into cipher text and back again. The explanation focuses on using modular arithmetic and powers to understand the underlying mathematics of secure messaging. Banks, Facebook, Twitter and Google use epic numbers - based on prime factors - to keep our Internet secrets. This is RSA ... Lattices are seemingly simple patterns of dots. But they are the basis for some seriously hard By the end of this video, you'll have a solid understanding of how RSA works, from key generation to Every time you enter your credit card details online, prime numbers are silently working behind the scenes to keep your data safe.
