A symmetric block cipher employing a substitution–permutation duo is an effective technique for the provision of information security. For substitution, modern block ciphers use one or more substitution boxes (S-Boxes). Certain criteria and design principles are fulfilled and followed for the construction of a good S-Box. In this paper, an innovative technique to construct substitution-boxes using our cubic fractional transformation (CFT) is presented. The cryptographic strength of the proposed S-box is critically evaluated against the state of the art performance criteria of strong S-boxes, including bijection, nonlinearity, bit independence criterion, strict avalanche effect, and linear and differential approximation probabilities. The performance results of the proposed S-Box are compared with recently investigated S-Boxes to prove its cryptographic strength. The simulation and comparison analyses validate that the proposed S-Box construction method has adequate efficacy to generate efficient candidate S-Boxes for usage in block ciphers.

“…This approach augments the strength of the resultant S-box using the permutation process. Authors using methods suggested in [20][21][22][23][24][25] used DNA computing to construct robust S-boxes and cryptographically strong ciphers. Analysis of these S-boxes and ciphers demonstrated their strength with respect to cryptographic criteria and against different attacks.…”

The security and privacy of data have been one of the major challenges for service providers dealing with public data since decades. To cope with these challenges, most of the organizations rely on the adoption of cryptographic methods for protecting data against any illegitimate efforts and attacks. Modern day cryptographic ciphers utilized one or more substitution-boxes (S-boxes) which facilitate to achieve strong security of plain data during encryption and legal decoding of it during decryption process. Security of ciphers is directly proportional to the cryptographic strength of S-boxes. This paper proposes to suggest an efficient, novel and simple method based on some modular operations for the construction of dynamic Sboxes with high nonlinear nature using heuristic evolution strategy. A large number of strong S-boxes can straightforwardly be erected by making slight variations in the parameters of the anticipated method. A specimen S-box is constructed and its critical performance analysis against standard security criteria including nonlinearity, strict avalanche criterion, bit independence criterion, differential uniformity, linear probability, and fixed points have been done to justify high cryptographic strength. The generated S-box is also applied to encrypt digital images to assess its cryptographic application performance. The performance and comparison study validates that the proposed S-box has better performance strength and true candidature for cryptographic application in the area of image security.

“…DNA computing is another prevalent field being used for the design of robust S-boxes to protect data. Researchers [22][23][24][25][26][27] have employed DNA computing for the design of sturdy S-Boxes to assist the encryption process and resultant S-boxes have proved attack-resilient. Several investigators have exploited other knowledge domains to produce substitution boxes like elliptic curve [28,29], graph theory [30,31], cellular automata [32], wavelet domain [33], optimization techniques [17,[34][35][36], Hilbert curve [37], backtracking [38], feedback systems [39], firefly algorithm [40], chaotic permutation [41], Galois Field [42], etc.…”

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. The overall security of a given cipher engaging an S-box greatly depends on the cryptographic forte of the respective S-box. Consequently, many researchers have used different innovative approaches to construct robust S-Boxes. In this article, an innovative and modest square polynomial transformation, the very first time, along with a novel affine transformation and a pioneering permutation approach to construct dynamic S-boxes is proposed. The proposed method has the capability to erect a huge number of robust S-boxes by applying minute changes in the parameters of transformation and permutation processes. An example S-Box is generated, and its recital analysis has been done using typical criteria including bijectivity, strict avalanche criterion, nonlinearity, bit independence criterion, linear probability, differential probability, and fixed-point analysis to check its cryptographic forte. This performance of the proposed S-box is placed side by side against state-of-the-art S-boxes to prove its strength. The performance and comparative analyses authenticate that the projected S-box possesses the true competence for its application in modern-day ciphers.
