Seminar on Computer Security and Cryptography


This weekly seminar on security and cryptography is organized by Cynthia Dwork and John Mitchell. Our goal is to cover a range of topics, from applications requiring security to engineering of secure systems to basic concepts and techniques in cryptography.

Time and Place

We will meet on Tuesdays at 4:15 in Gates 104. This room is just inside the Serra Street entrance to the Gates Building. (This is the building entrance that has Bill Gates' name over the door.)

Mailing List

Announcements will be posted to a mailing list called secure; to join that list, send email to with the line subscribe secure in the body of the message. There is an archive of this list.
