Cryptography of a Binary Image using a Modified Hill Cipher

Dr. V. Umakanta Sastry, D. S. R. Murthy, Durga Bhavani


In this paper, we have used a modified Hill cipher for encrypting a binary image. Here, we have illustrated the process of encryption by considering a couple of examples. The security of the image is totally achieved, as the encrypted version of the image, does not reveal any feature of the original image.


Keywords: Cryptography, Cipher, Binary image, Encrypted image, Modular arithmetic inverse.
