Cryptographic communication systems depend extensively on the Advanced Encryption
Standard (AES) block cipher algorithm. The encryption strength in the AES algorithm is …

The real-life incidents researched in academia have revealed that (possibly) state-level
efforts are made to camouflage the intentional flaws in the mathematical layer of an S-Box …

This paper proposes a lightweight and low energy encryption algorithm to secure voice
traffic over wireless networks. The proposed algorithm meets the requirements of voice traffic …

Abstract A Feistel Network (FN) based block cipher relies on a Substitution Box (S-Box) for
achieving the non-linearity. S-Box is carefully designed to achieve optimal cryptographic …

S-box plays a major role in the AES algorithm. The strength of S-box depends on the design
and algebraic constructions. In this paper, the construction of S-box will be built using a …
