comment Best choice of finite field for AES on a 4-bit microcontroller?
@ConradoPLG : so apart from the smaller LUT that $GF(2^4)$ might offer, would the overall arithmetic be more feasible and efficient for the 4-bit mcu since they will be manipulated in 4-bit?

comment Best choice of finite field for AES on a 4-bit microcontroller?
Let's just focused on the S-box (the most complicated operation) for now. I have learned that using composite field arithmetic and followed by extended Euclidean actually would reduce the size of the S-box. So in this case, would this method be suitable for 4-bit MCU? or using LUT tables would be a better choice?

comment Can one implement AES on 4-bit microcontroller?
thanks for the information. by any chance that AES in the field of GF((2^4)^2) would be efficient for 4-bit MCU in comparison to the AES in the field of GF((2^2)^4) and GF(((2^2)^2)^2)?
