A possible intrinsic weakness of AES and other cryptosystems
Published 30 Jun 2010 in cs.IT, cs.CR, and math.IT | (1006.5894v3)
Abstract: It has been suggested that the algebraic structure of AES (and other similar block ciphers) could lead to a weakness exploitable in new attacks. In this paper, we use the algebraic structure of AES-like ciphers to construct a cipher embedding where the ciphers may lose their non-linearity. We show some examples and we discuss the limitations of our approach.
