An Innovative Design of Substitution-Boxes Using Cubic Polynomial Mapping [PDF]
Symmetry, 2019 In this paper, we propose to present a novel technique for designing cryptographically strong substitution-boxes using cubic polynomial mapping. The proposed cubic polynomial mapping is proficient to map the input sequence to a strong 8 × 8 S-box meeting the requirements of a bijective function. The use of cubic polynomial maintains the simplicity of S-

Designing chaos based strong substitution box
2015 Eighth International Conference on Contemporary Computing (IC3), 2015Substitution boxes are the indispensable part of block ciphering techniques such as AES, DES, IDEA, etc. It is important to design effective S-boxes in an efficient way. In this paper, a method to generate effective S-boxes is proposed. A new technique is suggested to produce the input S-boxes candidates.

Hardware Software Codesign for a Hybrid Substitution Box
2017 30th International Conference on VLSI Design and 2017 16th International Conference on Embedded Systems (VLSID), 2017S-Box (Substitution-Box) is an important part of cryptographic algorithms such as AES, DES, Blowfish etc. This paper focuses on an efficient FPGA-based, reconfigurable AES S-Box design. This is the first S-Box architecture which uses hybrid search method (Z-TCAM), which enables to use the same design for encryption and decryption.

Designing Substitution Boxes for Secure Ciphers
International Journal of Innovative Computing and Applications, 2007In cryptography, a Substitution box (S-box) constitutes a cornerstone component of symmetric key algorithms. In block ciphers, they are typically used to obscure the relationship between the plaintext and the ciphertext. It is well-known that the more linear and the less auto-correlated the S-box is, the more resilient the cryptosystem that uses them ...

Alternative substitutional box structures for DES
2018 6th International Symposium on Digital Forensic and Security (ISDFS), 2018The DES algorithm is an important encryption protocol that has influenced many cryptology studies. It is still used today in many practical applications such as electronic passport. But it is an important problem that the design parameters of substitution boxes of this algorithm are unknown.

Globalized firefly algorithm and chaos for designing substitution box
Journal of Information Security and Applications, 2020Abstract This study adopted a metaheuristic approach based on the firefly algorithm (FA) optimization to generate an appropriate configuration for an 8 × 8 Substitution boxes (S-boxes). The FA can construct a strong S-box that satisfies the stipulated criteria by rapidly searching for the optimal or near-optimal feature subsets that minimize a given ...
