For Monday, November 6th, 2023:

  1. To Do:  Watch the first 32 minutes of This Video.  This is my friend, mentor and collaborator, Dr. Kristin Lauter, from Meta AI (formerly from Microsoft Research).  She’s giving a fairly generally accessible talk about a lot of different aspects of modern cryptography.  She has a lot of perspective on this because she’s in industry — she does the underlying math and the deployment and implementation.  She is one of the first people to propose using isogeny graphs in cryptography, for hash functions.  You’ll find lots of interesting stuff in here about practicalities and cryptography in the real world, like the future of cryptography after quantum computing.  It’s a great overview that should be just perfect for this moment in the course, where we’ve done the classical and pre-quantum crypto and are ready to dive into the newest of the new.  Note:  like a week or so after this video, SIKE (the isogeny-based proposal) was broken.
  2. Hand in some reactions to the video:  What questions did you have?  What did you learn?  3-6 sentences is fine.
