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 University 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.Conference and journals
