In the SubBytes step, each byte in the state is replaced with its entry in a fixed 8-bit lookup table, S; b ij = S(a ij). In the SubBytes step, each byte , in the state array is replaced with a SubByte (,) using an 8-bit substitution box. Before round 0, the state array is simply the plaintext/input.
The SubBytes operation applies a non-linear permutation (the S-box) to each byte of the state independently. The 8-bit S-box is composed of 3 smaller 4-bit S-boxes.

The Rijndael S-box was specifically designed to be resistant to linear and differential cryptanalysis. This was done by minimizing the correlation between linear transformations of input/output bits, and at the same time minimizing the difference propagation probability.
The Advanced Encryption Standard (AES), the symmetric block cipher ratified as a standard by National Institute of Standards and Technology of the United States (NIST), was chosen using a process lasting from 1997 to 2000 that was markedly more open and transparent than its predecessor, the Data Encryption Standard (DES).
Kupyna hash function uses Davies–Meyer compression function based on Even–Mansour cipher.The compression function consists of two fixed permutations, T ⊕ and T +, which are taken from the Kalyna block cipher [4] and consist of four operations: AddRoundConstant, SubBytes, ShiftBytes and MixColumns.
IPsec Virtual Private Network and more; IEEE P1363 covers most aspects of public-key cryptography; Transport Layer Security (formerly SSL); SSH secure Telnet and more; Content Scrambling System (CSS, the DVD encryption standard, broken by DeCSS)
The rebound attack is a tool in the cryptanalysis of cryptographic hash functions.The attack was first published in 2009 by Florian Mendel, Christian Rechberger, Martin Schläffer and Søren Thomsen.
