abstract = "Cellular Automata (CA) represent an interesting
approach to design Substitution Boxes (S-boxes) having
good cryptographic properties and low implementation
costs. From the cryptographic perspective, up to now
there have been only ad-hoc studies about specific
kinds of CA, the best known example being the ki
nonlinear transformation used in Keccak. In this paper,
we undertake a systematic investigation of the
cryptographic properties of S-boxes defined by CA,
proving some upper bounds on their nonlinearity and
differential uniformity. Next, we extend some previous
published results about the construction of CA-based
S-boxes by means of a heuristic technique, namely
Genetic Programming (GP). In particular, we propose a
reverse engineering method based on De Bruijn graphs to
determine whether a specific S-box is expressible
through a single CA rule. Then, we use GP to assess if
some CA-based S-box with optimal cryptographic
properties can be described by a smaller CA. The
results show that GP is able to find much smaller CA
rules defining the same reference S-boxes up to the
size 7by7, suggesting that our method could be used to
find more efficient representations of CA-based S-boxes
for hardware implementations. Finally, we classify up
to affine equivalence all 3by3 and 4by4 CA-based
S-boxes.",
