Can one implement AES on 4-bit microcontroller?
It is possible to implement AES on 4-bit microcontroller? As far as I know, AES on 8-bit microcontroller are common especially for light weight application such as the RFID. … I have yet to come across AES been employed on 4-bit microcontroller, therefore I have been wondering whether such implementation is feasible. …

Best choice of finite field for AES on a 4-bit microcontroller?
As the finite field of $GF(2^8)$ are isomorphic to $GF((2^4)^2)$, $GF((2^2)^4)$ and $GF(((2^2)^2)^2)$,
which of the fields is best suited and most efficient for 4-bit MCU and why? Would it be $GF((2^4 …
