Abstract
En 中文
• This research has been inspired by the growing utilization of local ring-based image encryption algorithms. • We have discussed the properties and conditions of Chain rings. Then, use this proposed ring for implementing data security measures. • The proposed method involves encrypting multiple images by constructing substitution boxes from subsets, which are not subgroups but have identity and invertibility axioms. The challenge of using subsets for encryption purposes is addressed by taking unit elements of the ring, picking a subgroup, and splitting it into two subsets. The substitution box is generated by one of the subsets and used for the substitution process, while the other subset is mapped to the Galois field. • The idea additionally seeks to explain why higher dimensions of S-boxes over non-chain rings are superior to Galois fields. Galois fields are widely used and require 8×28 bits of memory for GF(28) and 16×216 bits of memory for GF(216). The S-box is designed to accommodate 8×232storage cells. • Additionally, we used DNA sequence to make procedure more complex. • The next advantage is the excellent results achieved with the suggested approach for image encryption.
