Elements of RSA Algorithm and Extra Noising in a Binary Linear-Quadratic Transformations During Encryption and Decryption of Images
A. M. Kovalchuk, Nataliia Lotoshynska · 2018
An algorithm is proposed for encrypting-decrypting images using RSA algorithm elements, as the most cryptographically resistant to unauthorized decryption related to images with strictly clear edges. It is proposed to use RSA algorithm elements as coefficients of some linear-quadratic affine transformation. The proposed algorithm has a higher cryptographic stability compared to RSA algorithm.
