Ah, of course! I had not thought of that. By the way, everybody should take a look at the "Stick Figure Guide to the Advanced Encryption Standard (AES)": http://www.moserware.com/ -- Martin Geisler VIFF (Virtual Ideal Functionality Framework) brings easy and efficient SMPC (Secure Multiparty Computation) to Python.

Re: [viff-devel] AES slides from SPEED-CC
Hi, There are two talks about how to implement AES efficiently, this one http://www.hyperelliptic.org/SPEED/slides09/kasper-aes_speedcc09_slides.pdf describes on slide 9 how one will typically combine SubBytes, ShiftRows, and MixColumns into one operation operating on diagonals. I don't know if that will matter for us? I don't think so because lookup tables are not efficient in MPC.

[viff-devel] AES slides from SPEED-CC
Hi everybody, The slides from SPEED-CC are up: http://www.hyperelliptic.org/SPEED/ http://www.hyperelliptic.org/SPEED/timetable.html There are two talks about how to implement AES efficiently, this one http://www.hyperelliptic.org/SPEED/slides09/kasper-aes_speedcc09_slides.pdf describes on slide 9 how one will typically combine SubBytes, ShiftRows, and MixColumns into one operation operating on diagonals.
