Introduction to Cryptographic Attacks

Introduction to Cryptographic Attacks

Level of Instruction: Beginner

Instructed by: Matt Cheung

Abstract:

Using cryptography is often a subtle practice and mistakes can result in significant vulnerabilities. This workshop will cover many of these vulnerabilities which have shown up in the real world, including CVE-2020-0601. This will be a hands-on workshop where you will implement the attacks after each one is explained. I will provide a VM with a tool written in Python to execute the attacks. A good way to determine if this workshop is for you is to look at the challenges at cryptopals.com and see if those look interesting, but you could use in person help understanding the attacks. While not a strict subset of those challenges, there is significant overlap. The exercises will range from decrypting ciphertext to recovering private keys from public key attacks allowing us to create TLS cert private key and ssh private key files.
