DeepSec 2019 Workshop: Attacks on the Diffie-Hellman Protocol — Denis Kolegov & Innokentii Sennovskii *

This workshop is a hands-on task-based study of the Diffie-Hellman protocol and its modern extensions focusing on vulnerabilities and attacks. It is not a full day training, but it will be held during the conference. Everyone interested in applied cryptography and attacks connected to this topics should attend. Seats are limited!

Some of the topics that will be highlighted:
Diffie-Hellman key exchange
Elliptic-curve Diffie-Hellman
Variants of Diffie-Hellman protocol: Ephemeral, static, anonymous, authenticated Diffie-Hellman
X3DH, Noise and SIGMA protocols
Forward secrecy and post-compromise security
Small-subgroup attack
Pollard’s rho and lambda algorithms
Invalid curve attack
Curve twist attack
Protocol attacks (MitM, replay, KCI, UKS)

Labs:
Small subgroup attack against multiplicative group DH
Invalid curve attack against ECDH
Twist attack
KCI attack
Key Takeaways
Learn about Diffie-Hellman key exchange
Learn about applying Diffie-Hellman in modern protocols
Hands-on experience in implementation of the classic attacks
