WebFeb 1, 2024 · 2 I am struggling with a Diffie Hellman crypto challenge based on a client that uses a static private key. My goal is to trick the client into revealing enough information to reconstruct the private key (2048 bits) of this client. Let's call the vulnerable client Bob, while I am acting as a malicious Alice. WebOct 3, 2024 · Starter Diffie-Hellman Starter 1 (10 pts.) The Diffie-Hellman algorithm works with finite fields and modular exponentiation to allow to parties to exchange a shared secret. If you’re not familiar with this algorithm or with the math behind it I would suggest to check out the Wikipedia page to get started.
