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 order to ensure that the security of cipher is not breached, the matrix is shuffled after encrypting each character.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786200243621\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Softcover - 9786200243621","offer_id":39455346589789,"sku":"9786200243621","price":39.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/2996f9a8-9838-4f88-a500-470bc6486813.jpg?v=1773733031","url":"https:\/\/shop.autorenwelt.de\/en\/products\/a-modified-playfair-algorithm-with-international-nibbles-von-gideon-nuhu","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
