Course Description

Students who finish the training will get a certificate of completion.

The 2-day training Crypto Attacks and Defenses by Jean-Philippe Aumasson and Philipp Jovanovic is designed to familiarize developers and security professionals of any level with the most important concepts and best practices of modern cryptography. The training sheds also a light upon some of the most common vulnerabilities and failures found in cryptographic applications over the years and analyses how they could have been prevented.

In the lectures, students learn about all the important basics of modern cryptography. This includes notions such as secure randomness generation, block ciphers and stream ciphers, hash functions, authenticated encryption, key exchange protocols, digital signing schemes, elliptic curve cryptography, and formal security notions and attack models. The training also features topically focused talks on the Transport Layer Security (TLS) protocol, password protection, secure messaging, distributed ledger technologies, and post-quantum cryptography.

In the hands-on sessions, participants put into practice the notions and tools encountered during the lectures by being challenged to find, exploit, and fix vulnerabilities in cryptographic software. The exercises consist of a mix of made-up problems and examples of real-world vulnerabilities found in widely deployed systems.

There are no specific prerequisites for this course beyond a basic programming background.

Students should bring a notebook capable of running Virtualbox or VMware.
