Construction of Substitution Boxes Using Finite Fields
VFAST Transactions on Mathematics, 2023 Substitution boxes (S-boxes) play a crucial role in modern cryptographic algorithms, providingnon-linear transformations that enhance the security of data encryption. S-boxes are essentialcomponents of symmetric key ciphers, such as Advanced Encryption Standard (AES) and DataEncryption Standard (DES).

Construction of S-Boxes Using Different Maps Over Elliptic Curves for Image Encryption
IEEE Access, 2021 In this article, we present an encryption technique that can encrypt any digital data. The proposed scheme basically depends on a substitution-permutation network. Two separate bijective maps are used in the proposed algorithm.

Dual-Context Calculi for Modal Logic [PDF]
, 2020 We present natural deduction systems and associated modal lambda calculi for the necessity fragments of the normal modal logics K, T, K4, GL and S4. These systems are in the dual-context style: they feature two distinct zones of assumptions, one of which

Dynamic S-Box Design Using a Novel Square Polynomial Transformation and Permutation
IEEE Access, 2021 New era ciphers employ substitution boxes (S-boxes) which assist in the provision of security for the plaintext in the encryption phase and transforming the ciphertext on the receiver side into original plaintext in the decryption phase.
