Introduction and background

My most recent work advances the fields of anonymous credentials, randomizable signatures, zero-knowledge proofs, and lattices. I'm currently a Research Associate at the University of Edinburgh, working with Markulf Kohlweiss. I graduated in May from Brown University with a PhD in Computer Science. At Brown, my advisor was 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, Google scholar, or dblp. To contact me, you can use my email: scottgriffy+sgcom@gmail.com.

Service and miscellany

I previously ran the cryptography reading group at Brown. I was a PC member for PrivCrypt 2025, a shepherd for CANS 2025, and a subreviewer for Crypto, PKC, Eurocrypt, Asiacrypt, CANS, and IMACC as well as the journal Information and Computation. 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 video games, playing piano, and biking.
