Abstract A large number of images are generated and distributed in various fields every day. To protect the image information from being stolen during the network transmission, this paper proposes a multiple-image encryption algorithm based on genetic central dogma and three-dimensional (3D) bit planes. This paper simulates the genetic central dogma and defines the 3D bit planes. Firstly, k original images are transformed into 8-bit binary and converted into a 3D matrix; secondly, the 3D matrix is permutated by rotating the bit plane and performing permutation among the bit planes; thirdly, we encode the scrambled 3D matrix into DNA codes. The diffusion is realized by imitating the genetic central dogma and introducing RNA mutations; finally, the encrypted images are obtained by the RNA decoding operation. Experimental results and algorithm analyses indicate that the proposed algorithm has strong security and desirable performance.
