Modified Playfair Cipher for Encrypting Images
Keywords:
Playfair , Matrix, XOR operation ,algorithmAbstract
In this paper, a new extension of the Playfair cipher algorithm to encrypt images safer manner. The new method is created matrix of 16 × 16 based on the key being entered by the user to become more secretive, and then is taken image data byte by byte. In addition, the increasing complexity of the algorithm using masking and an XOR. That is, the key is used to generate XORed with the image to encrypt it. The experimental results showed that the use of slightly different secret keys, and the resulting encoded images makes it a completely different picture, and also encrypts the data that contain alphanumeric characters, integers, and most symbols
