Improving quality of DES S-boxes by cellular automata-based S-boxes
The Journal of Supercomputing, 2010In the paper we use recently proposed cellular automata (CA) based methodology (Szaban and Seredynski in LNCS, vol. 5191, pp. 478---485, 2008) to design the 6×4 S-boxes functionally equivalent to S-boxes used in current cryptographic standard known as Data Encryption Standard (DES).

Efficient implementations of S-box and inverse S-box for AES algorithm
TENCON 2009 - 2009 IEEE Region 10 Conference, 2009In this paper, improved architectures are proposed for implementation of S-Box and inverse S-Box needed in the Advanced encryption standard (AES) algorithm. These use combinational logic only for implementing SubByte (S-box) and InvSubByte (Inverse S-box).

Substitution boxes are central to symmetric ciphers. Many introductory cryptography books do not provide adequate coverage of this topic, in many cases no coverage at all. This is unfortunate, as s-boxes provide the primary source of nonlinearity in many symmetric ciphers.

Resource efficient cryptographic primitives become fundamental for realizing both security and efficiency in embedded systems like RFID (Radio-Frequency IDentification) tags and sensor nodes. Among those primitives, lightweight block cipher plays a major role to secure RFID's tag. One of the common lightweight block ciphers is PRESENT.

0.18um CMOS Technology in Implementation of S Box and a Modified S Box
2011Cryptographic algorithms are the most essential elements in designing the system security. Though there are numerous encryption systems used in security systems by various organizations, for the wider use, a particular encryption method is used as a standard. The internationally accepted and acclaimed algorithm is Advanced Encryption Standard.

Various probabilities of accidental linearities occurring in a random, reversible substitution lookup table (S-box) with m address and m contents bits are calculated. These probabilities decrease very dramatically with Increasing m. It is conjectured that good S-boxes may be built by choosing a random, reversible table of sufficient size.

Cellular automata based S-boxes
Cryptography and Communications-Discrete-Structures Boolean Functions and Sequences, 2019Cellular 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 χ nonlinear transformation used in Keccak.
