Abstract

Cryptography's aim is to construct schemes or protocols that can still accomplish certain tasks even in the presence of an adversary. A basic task in cryptography is to enable users to communicate securely over an insecure channel in a way that guarantees their transmissions' privacy and authenticity. This installment of Crypto Corner will explain what cryptography is about and how we can scientifically justify a cryptographic scheme's security.
