This research actually focused on reducing the size of the matrix that can be used to encrypt Unicode characters using a playfair algorithm. The previous work that attempted to encrpyt unicode characters using a playfair algorithm used a 256x256 matrix which is the normal size of matrix needed to encrypt unicode characters using a playfair algorithm. This research was able to reduce the size of the matrix to a 16x16. The reduction in the size of the matrix actually reduced the space that is needed for the matrix generation. As a result, it reduces the computation time by a sizable factor. In o...
