Description: In the article the modified RSA cryptosystem to generate matrix models and algorithms of cryptographic transformation of images. Proposed a matrix model that can be tailored to specific images, and be adapted to different types and sizes of. Presented formulas and algorithmic procedures steps encryption and decryption image dimension 128 × 128. Advantages and demonstrated capabilities and such modifications of RSA imaging model experiments programmed in Mathcad Professional.
Keywords: cryptographic transformation, modification system RSA, matrix models, encoding, decoding, image, adjustments
