This study introduces the Two-Dimensional Hybrid Chaotic Fourier Series and Nonlinear Coupled Oscillator Model (2- DHOCFSANCOM), which is integrated with compressed sensing technology, aiming to address the challenge of slow encryption speeds in agricultural Unmanned Aerial Vehicles (UAVs). The principal challenge in enhancing encryption speed is the inher- ently limited capacity of traditional chaos-based systems coupled with the complexity of their computational processes. By employing a sophisticated two-dimensional hybrid chaotic system, the 2-DHOCFSANCOM significantly enhances the security of image transmission in agricultural drones. This model surpasses existing chaos-based methods by integrating advanced Fourier series and nonlinear coupled oscillators, achieving improved pseudo-randomness and robustness in encryption. Moreover, incorporating the Bonouille function into the Discrete Cosine Transform (DCT) domain results in a sparser measurement matrix, which is pivotal for enabling efficient real-time encryption. The effectiveness of 2-DHOCFSANCOM in securely encrypting images from agricultural drones has been rigorously validated through simulations and analytical evaluations, employing sophisticated row, rotation, and matrix encryption techniques. Comparative analyses have further confirmed its enhanced safety performance. Compared to other models, the 2-DHOCFSANCOM demonstrates a notably higher Lyapunov exponent of 15.1039 and a sample entropy of 2.5, evidencing its superior chaotic performance and reliability in encryption.

“…By assaulting the ciphertext, the security of encrypted data may be compromised using the cryptanalysis approaches [10]. For systems that employ encryption to successfully safeguard sensitive data, cryptanalysis must be avoided [11] [12]. In the encryption and decryption stages, contemporary block ciphers use permutation and substitution procedures [13].…”

In present-day data communication, the imperative to safeguard information and shield it from a multitude of potential threats and attacks has gained significant prominence. One of the pivotal tools employed in the pursuit of data protection is the design of robust substitution boxes (S-Boxes). These S-Boxes often find their roots in the realm of chaotic maps, leveraging the inherent unpredictability and complexity of these mathematical constructs. An S-Box is an integral and critical component in the design of modern ciphers offering a means to enhance the security of data by introducing non-linearity and confusion into the encryption process. In this research endeavor, we propose the development of a novel chaotic map to create an S-Box that exhibits a notably high nonlinear score making it more formidable for potential adversaries to decrypt the ciphertext. To substantiate the efficacy of the proposed S-Box, a comprehensive analysis is done by comparing its performance using standard criteria including nonlinearity (NL), strict avalanche criterion (SAC), bit independence criterion (BIC), presence of fixed points (FP), linear probability (LP), differential probability (DP), etc. to other state-of-the-art S-Boxes. The comparative analysis reinforces the security fortitude of the proposed S-Box in meeting the rigorous demands of modern data security and presents a vital contribution to the ever-evolving field of cryptographic techniques and data protection in the digital age.
