We study the structure of an S-box based on a fractional linear transformation applied on the Galois field . The algorithm followed is very simple and yields an S-box with a very high ability to create confusion in the data. The cryptographic strength of the new S-box is critically analyzed by studying the properties of S-box such as nonlinearity, strict avalanche, bit independence, linear approximation probability and differential approximation probability. We also apply majority logic criterion to determine the effectiveness of our proposed S-box in image encryption applications.

“…To resist a common attack, a good cryptosystem should map the plain-image to a random cipher-image without exhibiting any pattern, and the image pixels should take as many random values as possible [38]. This can be measured in terms of the fractal dimension of the cipherimage and therefore by its scaling fluctuation exponent [39].…”

“…The values α = 1 and α = 1.5, correspond to 1/f noise and Brownian motion, respectively [41]. For secure encryption, the scaling exponent should be close to 0.5 and 1 for one-dimensional DFA and 2D-DFA, respectively [37], [39].…”

“…The results of the 2D-DFA tests show that in all modes, except mode 010-11 (S-box only), the scaling exponents α are close to 1 (Table 2), which suggests that there is no correlation between pixels and that there is no visually comprehensible information, whose pixels appear totally random. As pointed out in [39], this metric seeks to evaluate the level of perceptual security, so we can conclude that except for the 010-11 mode, the rest of the encryption modes are secure from the point of view of perceptual security. Figure 2 shows a plain-image and the cipher-images in the different operation modes, which do not reveal any information that would allow us to distinguish the original image.…”

In this work, we present a configurable encryption system based on the Encryption by Synchronization in a Cellular Automata (ESCA) system, which is a symmetric key algorithm based on the synchronization phenomenon of Cellular Automata with rule-90. With the aim of producing a flexible system to trade-off power consumption and security level, we implemented a pseudo-random number generator (PRNG) that can be configured with three different key sizes. This variable-length PRNG, together with the capability of bypassing specific modules in the rest of the system, allow us to operate under a wide range of applications. In particular, it would enable online adjustments in IoT and power-constrained devices to fine-tune them between a low-power consumption and a maximum-security level. The system can be implemented with 5956 gates, and it is designed to provide in a 0.5 µm CMOS process a throughput of 50 Mbps @ 37 mW, at the maximum-security level, and an energy consumption of less than 7 mW @ 30 Mbps at the lowest-security level, while still providing a satisfactory perceptual security metric.
