Hi, I'm Scott Griffy.
Introduction and background
I've done a lot of various computer-related stuff in my life. Currently, I'm very interested in applied and theoretical cryptography. Specifically, I've recently been working with randomizable signatures, lattices, and anonymous credentials. I'm in my 5th year as a PhD student at Brown University where I'm working with Anna Lysyanskaya. I previously worked at Intel as a security researcher/engineer and co-authored a patent there. I've listed below some of my publications, talks, and projects I've worked on. For more complete info, please see my CV or dblp. To contact me, you can use my email: scottgriffy@gmail.com or scott_griffy@brown.edu.Conference and journal publications
