“…Recently, several studies using post-processing algorithms have attempted to address this problem. The simple structure, fast results and easy implementation of the techniques based on post-processing method provide a great advantage especially against optimization-based designs [3,49]. The post-processing method has been shown to improve the nonlinearity value of an s-box structure with a nonlinearity value of 106.75 to 110 at the end of 12*255*255 processing steps in the worst-case scenario.…”

The demonstration that the nonlinearity criterion of substitution box (s-box) structures based on the random selection principle can be improved through post-processing techniques has created a new research area. The necessity of obtaining sbox structures that can be given as input to these post-processing algorithms has emerged. In this study, a study was carried out on how to obtain sbox structures based on solar panel data. The cryptological properties of the obtained sbox structures were tested using five basic evaluation metrics and compared with similar studies in the literature. The successful results indicated that these outputs may have various practical applications in the future.

“…Sensitivity is demonstrated through a SAC, indicating that approximately 50% of the key undergoes inversion in each round when any bit in the initial key is altered [18]. To validate this sensitivity, we modified any bit of the initial key listed in Table IV, resulting in 10 new round keys.…”

This research investigates the security loopholes inherent in the traditional Advanced Encryption Standard (AES) key expansion mechanism, notably its sequential and reversible configuration that permits the derivation of subsequent round keys from any obtained round key. To counteract these vulnerabilities, we introduce a novel key expansion strategy that leverages dynamic Substitution-boxes (S-boxes) alongside the innovative application of cross-coupled lattice mapping. Our approach includes the development of a new one-dimensional chaotic map integrated into the cross-coupled map lattice to enhance its chaotic dynamics. Utilizing this enhanced lattice, we devise a dynamic S-box generation method. This method, rooted in the cross-coupled lattice mapping of a spatiotemporal chaotic system, yields an S-box with unique security features. Rigorous testing and validation demonstrate the S-box's superior defense against a broad spectrum of cryptographic threats. Furthermore, by embedding cross-coupled lattice mapping into the key expansion routine, we elevate the algorithm's complexity and render it non-reversible. This iterative implementation of the lattice mapping negates the possibility of deducing any round key or the original key from a single round key. Exhaustive experimental analyses validate the proposed key expansion algorithm's independence and adaptability, underscoring its improved security capabilities. The algorithm exhibits robust resistance to conventional side-channel and differential attacks, performing exceptionally in real-world application scenarios. Our study delivers a groundbreaking key expansion methodology that significantly enhances cryptographic security, offering a substantial contribution to the encryption domain and strengthening the overall security infrastructure of encryption algorithms.

“…In this section, it is described how the proposed method uses the S-Boxes substitutions. The proposed mechanism takes advantage of the S-boxes designed by Farah et al [45], Fatih et al [46], and Islam et al [47].

The enabling devices and sensors of the Internet of Things (IoT) are characterized by devices with limited resources, where the computation and the energy consumption should be optimized. Application fields such as healthcare or multimedia content bring up security and privacy issues. Therefore, data security is critical. However, to obtain it, high computing resources are required. To avoid it, in this work, we propose a lightweight method to protect data transmissions in sensor devices. We present the GS3 method, it is based on a procedure set by Generating the data block, Shuffling, Scrambling, and applying Substitution boxes on the data. Our experimental results will show that GS3 introduces a minimal overhead, of just two bytes corresponding to the Cyclic Redundant Control 16 (CRC16) integrity control in the length of the messages concerning the original data. According to the execution time with respect of other encryption-based methods, even a 50% less than Chacha20 algorithm, as fewer steps and simpler computation procedures are required. Therefore, GS3 is a good choice to be used in resource-constrained IoT devices in which data integrity and security are required, taking into account the data freshness.
