A nonlinear substitution operation of bytes is the main strength factor of the Advanced
Encryption Standard (AES) and other modern cipher systems. In this paper we have …

S-boxes are used in block ciphers as the important nonlinear components. The nonlinearity
provides important protection against linear and differential cryptanalysis. The S-boxes used …

Substitution boxes, or s-boxes, provide the primary source of non-linearity in symmetric
cryptographic primitives. There are a variety methodologies used to design s-boxes. One …

Governmental bodies, such as military and national security agencies, keep looking for
proprietary encryption algorithms to secure their confidential communication applications …

Translation polynomials used in the construction of advanced encryption standard (AES) S-
box are computed for each modulus polynomial and carry out the analysis based on the …

A hybrid encryption scheme based on SPN and Feistel structures is proposed. In this
scheme, the round functions of AES are modified by considering block size 33× instead of …

The AES S-Box is the only part of the standard responsible for providing the nonlinearity
needed to deal with the linear and differential attacks. This fact emphasizes the necessity for …

Due to the fact that encryption operations performed by any protocols increase the number
of operations and also slow down the rate of data being sent or received over WiMAX …

The demand for security in wireless communication channels is rapidly growing. In this
exertion a proposed encryption unit which adopts the AES (Advanced Encryption Standard) …

There are many encryption algorithms, but Advanced Encryption Standard (AES) 128-bit to
be used in many applications for protecting sensitive information/data. Typical examples are …
