On low degree polynomials in 2-round AES
Recent observations on polynomial structures of AES-like round functions are analysed in this note. We present computational evidence that input/output bits of AESlike 2-round transform up to 40-bit, constructed with 8-bit AES S-boxes, do not satisfy any relations of degree 3. So it is very unlikely that actual AES 2-round transform admits any relations of degree ≤ 3.
