A steganographic algorithm linked to magic squares (Original)
Keywords:
steganography; magic squares; asymmetric algorithmAbstract
The present work corresponds to the introduction of a new algorithm in the preparation of the students of the master's degree, Applied Mathematics of the University of Havana, corresponding to the Postgraduate course, "Steganography and Applications", in addition to the MININT members of In the province of Guantanamo, a novel steganographic algorithm linked to the spatial domain is presented, which uses a 128-bit private key together with the magic squares, with the purpose of hiding highly classified information, so that the resulting image after the insertion is not noticeable to any electronic monitoring system. The proposed algorithm improves in the level of imperceptibility analyzed through the PSNR values; In addition, it provides a quasi-perfect and safe system-stego system reflected in the values achieved for relative entropy (Er).
