Announcements

Please turn in hardcopy of the paper you are basing your project on along with your writeup.
The final-discussion time slot you signed up for (March 17-18)
I will ask students to present in the same order as their signup slot.

General information

Lectures to date - grows with each class

Class notes - evolving course notes, co-written with Mihir Bellare.

Katz-Lindell book has good topical overlap with the above.

Course information sheet - please read this - and Lectures for 2007 - doubles as a syllabus, as topics this year will be similar

Class pictures - In living color

Project information - Projects are due the last day of class

PS 2 (due Feb 9)

PS 3 (due Feb 23)

PS 4 (due Mar 9)

A bit of supplemental material

Practical, ciphertext-only attack on a substitution cipher (the first few pages of a nice article by P. Diaconis)

Example blockciphers: DES (1975), AES (Rijndael) (1998), and, for something very recent, Threefish (2008) (embedded in SHA-3 candidate Skein).

More on DES: DES is not a group (K. Campbell and M. Wiener) (See Section 5, attributed to D. Coppersmith), and why cycles of E1 o E0 are short) (D. Coppersmith).

More on AES: Cache-timing attacks on AES (D. Bernstein), and New AES Software Speed Records (D. Bernstein and P. Schwabe).

A possible project paper I wouldn't mind hearing about (M. Nandi).
