“…The Substitution Box (S-Box) is critical in block ciphers; it creates inconsistency between the initial and encrypted speech signals. [17] As a result, several researchers have attempted to develop a strong S-Box that can be used in the substitution phase and substitutes the standard S-Box to provide a high degree of security [5].…”

This paper proposes the establishment of a secure encryption system for data transmission that includes three stages: first stage is a scrambling stage that is divided into scrambling of different sizes blocks and scrambling bits, the second stage is the use of DNA code to flip the bits and the third stage is the encryption using the Substitution box by 256 keys. The scheme is analysed using a variety of metrics. The findings demonstrate that the proposed system is significantly more reliable and robust against various forms of attacks than several recent related speech signal encryption systems.

“…Also several studies were carried out for S-box constitution from chaotic system by using FPGA Parallel Multi-Layer Selector Substitution Boxes based on the Lorenz Chaotic System and its FPGA implementation were carried out [11]. Speech encryption using a chaotic system and an S-box table on FPGA was studied [12][13][14][15]. Besides several studies were done on image encryption systems by using chaotic systems based S-box Table implemented on FPGA [16][17][18] In this study it is aimed to constitute a FPGA accelerated S-box via fractional order Liu chaotic system.…”

Substitution box(S-box) has an important duty in encryption. In recent years plenty of S-box designs by chaotic systems have been studied. In this paper a high speed S-box constitution from fractional order Liu system on FPGA is proposed. The design was implemented by using Xilinx System Generator(XSG) toolbox in MATLAB/Simulink software in single precision floating point numbers format and a low cost Basys 3 FPGA trainer card was used. In addition, numerical fractional order equations was solved by using Grünwald-Letnikov(GL) method with 1024 elements length. The S-box table was constructed about 0.137s. After all performance analyzes as nonlinearity, strict avalanche criterion, differential probability, bits independent criterion, and equiprobable input/output XOR distribution, were performed. The performance analyzes shown that the design was satisfactory.
