There are two talks about how to implement AES efficiently, this one

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.
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):
VIFF (Virtual Ideal Functionality Framework) brings easy and efficient
SMPC (Secure Multiparty Computation) to Python. See: http://viff.dk/.
