Some smaller AES implementations

You asked for smaller AES implementations, here you are:
http://www.ti.com/tool/aes-128
http://dominik.cc/projekty/avr-aes/

Warning: They have the same timing vulnerability in GF multiplication.

The issue provides two external AES implementation links and notes a timing vulnerability in GF multiplication, but names no repository file or test. Review those references and clarify the desired implementation, scope, and acceptance criteria before starting; the payload does not define what completion would look like.
