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.

2012 International Conference on Advanced Computer Science Applications and Technologies (ACSAT), 2012
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.
