My name is Hernán Darío Vanegas Madrigal. I have a Bachelor’s degree in Computer Engineering and Bachelor’s degree in Mathematics. I’m working as a MPC Research Engineer at HashCloak Inc. Also, I am an MSc. student in Applied Mathematics at National University of Colombia. I am interested in cryptography, particularly, in Secure Multiparty Computation (MPC). In general, I am interested in applying abstract mathematic concepts to computer science areas.
Despite I’m working with MPC constantly, I am always learning it. There is always something that I don’t know and new things come up every day.
In my master’s thesis, I studied how to compute the edit distance between two DNA chains privately using multi-party computation (MPC) protocols based on secret sharing (SS). This study includes the evaluation of the pros/cons and the efficiency of these implementations. I used the MP-SPDZ framework for this work.

This blog is intended to share a little bit of my findings, opinions and maybe some knowledge. But also, it’s for practicing my english. So, it is fairly possible that you will encounter here typos, bad grammar, and even bad redaction. Not without saying that I will do my best to improve my wiriting and avoid such mistakes. And with some frequency, I will post content also in spanish.
