...there was a functional AES C implementation for AVR on avrfreak a few years ago if I remember well.

Anyway this document is helpfull for speed improvement on 8bit AVR uC:
https://online.tu-graz.ac.at/tug_online/voe_main2.getvolltext?pDocumentNr=91534

...and the implementation source is here (aes.c and aes.h):

Already got both of them.....

there is also an additional one: AVR411

and

another one more complete....: AVRCryptolib

In my case the help i need is: did someone checked those algorithms? if so, before implementing it by myself, did someone wrote an ultra optimized one?
