How to Commit to a Private Function

  • This is an online-only event.
    See description for details.

Dan Boneh heads the applied cryptography group and co-direct the computer security lab at Stanford University. His research focuses on applications of cryptography to computer security. His work includes cryptosystems with novel properties, web security, security for mobile devices, and cryptanalysis. He is the author of over a hundred publications in the field and is a Packard and Alfred P. Sloan fellow. He is a recipient of the 2014 ACM prize and the 2013 Godel prize. In 2011 Dr. Boneh received the Ishii award for industry education innovation. Dan Boneh received his Ph.D from Princeton University and joined Stanford University in 1997.

Public Lecture


A cryptographic commitment scheme lets one party commit to some data while keeping the data secret. The committer can later open the commitment (uniquely) to reveal the committed data. Commitment Schemes are a fundamental tool in cryptography and have been studied for over four decades. In this talk we will generalize this basic concept, and in particular, develop ways to commit to a secret function. The commitment reveals nothing about the function, however, the committer can later “open” the function at any point, namely efficiently prove that for a given (x,y) the function evaluates to y at the point x. We will discuss some societal applications of this concept, as well as the beautiful algebraic questions that come up when constructing it. The talk will be self contained. This is joint work with Wilson Nguyen and Alex Ozdemir.
