| | | | | Motivation In my quest to understand zero knowledge proofs from the ground up, I've decided to go back to the basics, and really understand how everyday cryptography tools work, not just how to use them. In this post, I'll attempt to explain how and why the diffie hellman key exchange protocol works, along with proofs and a working example. The examples are purely for educational purposes only! Introduction The Diffie-Hellman key exchange protocol is an algorithm that allows two parties to generate a uni... | |

| | | | | So far in this series we've seen elliptic curves from many perspectives, including the elementary, algebraic, and programmatic ones. We implemented finite field arithmetic and connected it to our elliptic curve code. So we're in a perfect position to feast on the main course: how do we use elliptic curves to actually do cryptography? History As the reader has heard countless times in this series, an elliptic curve is a geometric object whose points have a surprising and well-defined notion of addition. | |

| | | During 2021 I had access to a facility equipped with an alarm system from Securitas Direct. I had access as a regular user to Securitas Direct's My Pages at mypages-pro.securitas-direct.com, which is used to administer some aspects of one's security alarm installation. That web application suffered a CWE-384 Session Fixation vulnerability which can be used by an attacker in a so-called Man-In-The-Middle (MiTM) position.
