“…For the encryption process, the PSNR must be decreased, while the MSE and EQ must be increased and EQ must range between 528930 and 1587785. From this point, we note that the proposed method achieved better results and the EQ of [ 45 ] fewer than the appropriate value. Since the results of the proposed S-Box were better when compared with the other previous works, the encryption results will also be better when compared to the earlier works.…”

“…The range of AC should be between 0 and 1, with the best value being 0.5, which results in an S-Box satisfying the avalanche criterion. The avalanche of the transformation function for the S-Box can be obtained using the following equation [ 44 , 45 ]:

“…There is another comparison for the reference and the proposed work the entropy for (Lena and Baboon) image in reference [ 44 ] is (7.903 and 7.902) and for the proposed work is (7.991 and 7.998) and the appropriate value must be near 8. There are another comparisons between reference [ 45 ] and the proposed work. These are according to PSNR, MSE, and EQ evaluation measures: (1) In the reference [ 45 ], these are (0.0047, 10150.39, and 133266) for the Peper image, and (0.0053, 9016.81, and 12609) for the Lena image.…”

Background and Aim: due to the rapid growth of data communication and multimedia system applications, security becomes a critical issue in the communication and storage of images. This study aims to improve encryption and decryption for various types of images by decreasing time consumption and strengthening security. Methodology: An algorithm is proposed for encrypting images based on the Carlisle Adams and Stafford Tavares CAST block cipher algorithm with 3D and 2D logistic maps. A chaotic function that increases the randomness in the encrypted data and images, thereby breaking the relation sequence through the encryption procedure, is introduced. The time is decreased by using three secure and private S-Boxes rather than using six S-Boxes, as in the traditional method. Moreover, the CAST encryption algorithm was modified to be used on the private keys and substitution stage (S-Boxes), with the keys and S-Boxes of the encryption algorithm being generated according to the 2D and 3D chaotic map functions. The proposed system passed all evaluation criteria, including (MSE, PSNR, EQ, MD, SC, NC, AD, SNR, SIM, MAE, Time, CC, Entropy, and histograms). Results: Moreover, the results also illustrate that the created S-Boxes passed all evaluation criteria; compared with the results of the traditional method that was used in creating S-Box, the proposed method achieved better results than other methods used in the other works. The proposed solution improves the entropy which is between (7.991–7.999), reduces the processing time which is between (0.5–11 s/Images), and improves NCPR, which is between (0.991–1). Conclusions: The proposed solution focuses on reducing the total processing time for encryption and decryption and improving transmission security. Finally, this solution provides a fast security system for surgical telepresence with secure real-time communication. The complexity of this work needs to know the S-Box creation method used, the chaotic method, the values of the chaotic parameters, and which of these methods was used in the encryption process.

“…The resulted algorithm was analyzed and produced desired encryption strength results. On the other hand, other suggested enhanced s-box algorithms do not depend on a key or external parameter [11]. The initial s-box can be considered a starting point, and the succeeding sboxes all depend on the initial s-box, such as the APA s-box, S8 AES s-box [12], and Gray s-box [13].…”

Sensitive data has to be protected from the public.• A strong encryption algorithm is required for protecting images. • Computing speed is growing, making algorithms vulnerable to attacks. • An enhanced AES-CBC algorithm is evaluated for the encryption proposed. • The algorithm satisfied the required standards and passed all tests.The Advanced Encryption Standard (AES) has become an attractive encryption method for high security and fast implementation. The encryption algorithm is approved as a standard for widely-used communication and data processing units. However, the advance in technology and the introduction of quantum computers made the encryption scheme vulnerable to attack. Different attack procedures are continuously developed to attack end decrypted important and sensitive data. This paper evaluated an enhanced Advanced Encryption System operating in Cipher Block Chaining mode, suggesting a promising solution for resisting future attacks. The approach depends on a time-dependent initialization vector that produces the initialization vector block depending on the epoch time without sharing any encryption key. The evaluation process includes correlation analysis, global and local Shannon entropy analysis, chi-square analysis, histogram analysis, and differential analysis. The results showed that the enhanced encryption scheme is reliable and can resist most cyber-attacks without exposing any encrypted data to the public. The results were compared with previously published and tested algorithms and found to satisfy and exceed the minimum requirement. So, the encryption method can be implemented safely in future communication channels or used in the file encryption process.
