“…In this research, a hybridization of a chaotic system based on a cast encryption algorithm is used to encrypt different types of digital images. CAST-128 is a procedure designed to be used as a symmetric encryption algorithm, which was developed by Carlisle Adams and Stafford Tavares [ 27 , 28 , 29 ]. CAST-128 is a classical feistily network, consisting of 16 rounds and operating based on 64-bit blocks of plaintext, with 64-bit blocks then being produced as a cipher text.…”

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.

“…K.H. Boey et al, power analysis has been applied to attacks on CAST-128 which is the only algorithm that has not been practically broken either on ASIC or GPGA [5]. Author uses 128 bits of secret key within 300, 500 power traces to reveals the outlines an approach on attacking the registers rather than S-box.…”

An optimized key scheduling algorithm for the 64-bit block cipher CAST-128 by using dynamically substituting of S-box. In this regard, an attempt has been made to modify key scheduling algorithm for generating subkeys of a secret-key block cipher which is CAST-128 algorithm so as to enhance performance by modifying the generation of subkeys using dynamic substitution of S-box. The CAST-128 uses four static substitution of S-box to generate subkeys, where as the proposed structure generates subkeys using substitution of S-box dynamically to provides the performance of CAST-128. The approach considers different security aspects and metrics evaluation for verification
