Abstract

The cryptographic algorithm zoo includes stream ciphers, block ciphers, hash functions, MAC algorithms, authenticated encryption schemes, public key encryption, and digital signature schemes. Each of these algorithms has different security properties and serves a specific purpose. In this session, we describe these cryptographic building blocks, explain what they can and cannot do for you and how to use them correctly. After the session, you will be able to select the right algorithm for the challenges you're trying to solve. We will also touch on the challenges posed by quantum computers.
