ECDSA: Handle with Care
The elliptic curve digital signature algorithm (ECDSA) is a common digital signature scheme that we see in many of our code reviews. It has some desirable properties, but can also be very fragile. For example, LadderLeak was published just a couple of weeks ago, which demonstrated the feasibility of key ... Read More
Themes from Real World Crypto 2020
Over 642 brilliant cryptographic minds gathered for Real World Crypto 2020, an annual conference that brings together cryptographic researchers with developers implementing cryptography in the wild. Overall, RWC 2020 was an impressive conference that demonstrated some amazing work. Here we explore three major themes that emerged: Crypto bugs are everywhere...Whether ... Read More
Multi-Party Computation on Machine Learning
During my internship this summer, I built a multi-party computation (MPC) tool that implements a 3-party computation protocol for perceptron and support vector machine (SVM) algorithms. MPC enables multiple parties to perform analyses on private datasets without sharing them with each other. I developed a technique that lets three parties ... Read More
