Hi, I'm Scott Griffy.

Introduction

I've done a lot of various computer-related stuff in my life. Currently, I'm very interested in applied and theoretical cryptography and how to use it to solve societal and technical problems. Specifically, I've recently been working with randomizable signatures, lattices, and anonymous credentials.

Education/Jobs

I'm entering my 5th year as a PhD student in computer science at Brown where I'm working with Anna Lysyanskaya. I graduated from Portland State University with a master's in computer science in June 2019. I got my bachelor's in computer science from Oregon State University. I worked at Intel as a security researcher/engineer and co-authored a patent there. For more info, please see my CV.

Service and miscellany

I (along with others) run the cryptography reading group at Brown, so if you're in the area and would like to come present your work to the group, please reach out to me at myfirstname_mylastname@brown.edu. I was a PC member for PrivCrypt 2025, a shepherd for CANS 2025, and a subreviewer for Crypto 2025, Eurocrypt 2024, Asiacrypt 2024, CANS 2024, Crypto 2024, and IMACC 2023. I used to help out at a club called "GEMS" (Game & Entertainment-Making Students) at Portland State University. In my free time I enjoy developing videogames, playing piano, and biking.
