Abstract

Introduction: Privacy is particularly important in protecting data when it comes to the realm of digital communications. Aspects of the importance of hybrid chaotic encryptions are the hybrid chaotic map-based encrypting method introduced conditional in this paper. The first hybrid chaotic- encrypting method based on Sine mapping system, and Hénon mapping system., In addition to the use of extreme sensitivity and randomness of chaotic systems, hybrid chaotic encryption enables strong-average image encryption. The hybrid chaotic encryption method is a stepwise process comprising four primary processes and constituents. These processes include. Hence, the image is secret-image by the hybrid chaotic map, which is hybridness of Sine map+ Hénon map. Randomization7 ing the hybrid chaotic map further increases encryption based on complexy. Finally, given the. The second phase also. The PSNR value of 9.2122 dB shows that encryption is especially effective in concealing image data. Moreover, the original image has an entropy of 7.4451, while the encrypted image has a greater total entropy of 7.9993, which means it is closer to the true randomness. The correlation among adjacent pixels in the encrypted image is significantly lower as well, being 0.97193, 0.98503, 0.95933 for horizontal, vertical, and diagonal correlation, respectively. Objective: By mixing Sine and Hénon maps in this way, this will allow us to provide a powerful and secure encryption protocol for the transmission of images. The hybrid chaotic system ensures reliable recovery of the original image while effectively improving data security. Theoretical Framework: The creation of modern picture encryption methods is justified by this theoretical framework, which integrates hybrid systems theory, cryptography principles, and chaos theory. The hybrid chaotic model overcomes traditional image encryption weaknesses including low entropy, poor correlation, and a restricted keyspace by bringing together the advantages of multiple maps. Method: Using hybrid chaotic maps, this technique offers a strong, safe, and practical way to encrypt images. Compared to single chaotic systems, hybrid systems are more unpredictable and resilient. Using a variety of objective security indicators, the performance is verified. Results and Discussion: This technique is a valid, secure, and practical way to encrypt images using hybrid chaotic maps. Hybrid systems are more unpredictable and resilient than single chaotic systems. The performance is verified based on multiple objective security indicators. Research Implications: The results of using the recommended hybrid chaotic image encryption approach are presented along with a series of trials to assess the effectiveness. The encrypted images are statistically, visually, and cryptographically evaluated and compared. Originality/Value: By creating and validating an innovative hybrid chaotic encryption algorithm that outperforms existing algorithms, this study makes a unique contribution to the area of cryptographic image security. The drawbacks of systems that are traditional and that use just one chaotic map. The uniqueness and worth of this work are clear in a number of important areas.
