“…The Table (7) presents a comparison of a proposed algorithm with six algorithms from literature based on two performance metrics: NPCR and UACI. The proposed algorithm achieved an NPCR value of 99.6002, which is slightly lower than Algorithm [1] (99.9353), but higher than Algorithms [2][3][4][5][6] (ranging from 99.65 to 99.617). The proposed algorithm also achieved a higher UACI value of 35.3623, as compared to all six previous algorithms (ranging from 33.38 to 33.64).…”

This research paper introduces a novel encryption algorithm that utilizes a hyper six-dimensional chaotic system to enhance image security. The algorithm incorporates randomization, switching, diffusion, and XOR operations in a series of stages to ensure robust encryption. Two sets of keys are generated using the chaotic system, adding random and unpredictable elements to enhance the algorithm's security. During the encryption process, the image's color values are transformed into red, green, and blue vectors, enabling precise manipulation at the pixel level. Pseudo-random shuffling, guided by chaotic keys, introduces an additional layer of randomness, making the encrypted image resistant to decryption and tampering attempts. XOR operations further modify the pixel values, while interconnecting the color vectors enhances the encryption's complexity and security. Experimental evaluation of the proposed algorithm demonstrates its efficacy. A high PSNR value of 7.9997 indicates preserved image resolution after encryption. The NPCR value of 99.6002 indicates robust resistance to pixel modifications and the UACI value of 35.3623 showcases uniform pixel distribution. The algorithm also offers a substantial key space of 2 947 , further strengthening its overall security. Notably, its sensitivity of 10 15 highlights its resilience against potential attacks.

“…Chaos, is sometimes known as the "butterfly effect [16].Is a phenomenon that results from the complex, aperiodic behavior of deterministic systems that exhibits remarkable sensitivity to minute changes in initial conditions [15].In the framework of Shannon's confusion and diffusion principles, this characteristic of chaos has been used in cryptography [13]. Chaotic events have demonstrated potential as a source of pseudo randomness in information security by utilizing their mixing property and great sensitivity to tiny fluctuations [2], [13], [17].…”

In the era of data-driven applications and resource-constrained devices, the need for lightweight algorithms has become increasingly important. Lightweight algorithms refer to computational techniques that strike a balance between efficiency and resource utilization, making them well-suited for low-power devices, embedded systems, and scenarios with limited computational capabilities. For the new encryption method PRESENT, which was put forth in 2007, S-box directly affects the algorithm's security, whereas the p-layer mostly functions as a confusing factor during the encryption process. This paper provides a brief explanation of the PRESENT algorithm's operation and suggests an enhanced S-box and p-layer to address the issue that the main PRESENT S-box and P-layer have an anti-fixed point. The random generate of S-boxes and P-layers for PRESENT algorithms using 6D chaotic systems to generate 10 new S-boxes and 10 new P-layers. Finally, the security analysis has been completed, and the results indicate that the chaos S-box and P-layer are better able to with stand differential attacks and linear assaults and are suitable for protecting sensitive data.

“…As a result, numerous approaches and procedures have been created in an attempt to identify the fastest and most secure method for encrypting digital image content [1] [2]. Image encryption presents a number of challenges, including encryption quality, processing time, 88 and difficulties associated with the encryption key (such as key space and key exchange in the case of symmetric key) [3][4][5]. A more robust encryption technique is indicated by a higher level of noise and a more unintelligible encrypted image.…”

The rapid tech growth and widespread internet usage caused a surge in sharing multimedia (text, images, videos, audio) across public networks. Protecting this data is vital, demanding encryption to prevent unauthorized access. Image encryption distorts images for security. This paper highlights encryption's vital role in safeguarding multimedia, especially amid rising internet use and media exchange. It introduces a novel solution: a chaotic three-dimensional system for color image encryption. The study scrutinizes system traits using math software. It employs a new chaotic system to generate a crucial key sequence for pixel scrambling. Utilizing stream cipher encryption enhances security. Extensive security analysis tests its resilience against attacks like histogram and correlation techniques. Results are promising: a fairly uniform histogram, minimal correlation among pixels nearing zero, and entropy close to the ideal. Metrics like NPCR and UACI almost match ideal values, ensuring high security. Experiments confirm its effectiveness in encrypting diverse color images. The approach guarantees a uniform histogram, minimal pixel correlation nearing zero, entropy near the ideal value (8), and NPCR/UACI values close to ideals (99.61191% and 33.41068% respectively).
