The Future of Cryptography

Abstract

We’ve seen where cryptography came from, but where is it going? In this article, I pose a number of unsolved problems: challenges that face us with which we have to deal. Some of them are elephants in the room that we’re all ignoring, or if not ignoring we’re noting that they’re in the room, take up a lot of space, and do make it hard to dust, but then we go back to the previous subject. Others are genuinely hard problems without a good solution. Still others are tradeoffs. Consider this a tour of stopoffs at interesting problems and surprising things.
