Lecture 10:
The Return of Paco
Background
just got here last week
finished degree at MIT week before
Philosophy of advising students
don’t come to grad school to implement someone else’s idea
can get paid more to do that in industry
learn to be a researcher
important part of that is deciding what problems and ideas are worth spending time on
grad students should have their own project
looking for students who can come up with their own ideas for research
will take good students interested in things I’m interested in – systems, programming languages & compilers, security
rest of talk – give you a flavor of the kinds of things I am interested in
meant to give you ideas (hopefully even inspiration!) but not meant to suggest what you should work on

*** RIJNDAEL *** Selected by NIST for the Proposed AES
October 2, 2000
[Note: Apparently, one of our NIST servers was down for while today, making the webcast inaccessible. It also has led to a delay in these AES pages being updated. We will try to make the "archived" webcast available as soon as possible.]
