This study suggests a novel color multiple image encryption technique using “Algebra-Chaos Amalgamated 256-length-12-bit random sequence” and DNA Transform. The proposed random sequence (S-box) has the property of occupying small computer memory space as regards to the existing S-boxes. Moreover, for simplicity and novelty, 1D sin chaotic map and 1D logistic map are mixed to generate a 1D mixed Chaotic map. Initially, a 12 × 12 (256-length-12-bit) S-box is designed by the unit elements of a chain ring, and then it is mixed with the 1-D mixed chaotic map that results triplets T₁,T₂ and T₃ of high random behavior. A multiple digital image encryption is performed by using the triplet for substitution-permutation along with DNA transform. The proposed image encryption technique enhances key-space size. Moreover, the experimental results show that the proposed technique of encryption for digital medium has extra ordinary resistance against the well-known attacks.

这项研究提出了一种新颖的彩色多图像加密技术，该技术使用了“代数-混沌融合的256长度12位随机序列”和DNA转换。所提出的随机序列（S-box）具有相对于现有S-box占用小的计算机存储空间的特性。此外，为了简单和新颖，将一维正弦混沌映射图和一维逻辑映射图混合以生成一维混合混沌映射图。最初，通过链环的单元元素设计一个12×12（256长度12位）的S-box，然后将其与一维混合混沌映射图混合，从而生成三元组T ₁，T ₂ 和 T ₃高随机行为。通过使用三元组进行置换置换以及DNA转换，可以进行多重数字图像加密。所提出的图像加密技术增强了密钥空间的大小。此外，实验结果表明，所提出的数字媒体加密技术对已知攻击具有额外的普通抵抗力。
