Abstract :

In this paper we have extended the DJSSA algorithm one step further. The present work proposes a key matrix of size 65536x256 which contains all possible 3- lettered words. The present method uses a simple randomization technique[1] to make this key matrix random. So the complexity of finding the actual key matrix will be 16777216! trial runs and which is intractable. In the current modified DJSSA method the we added one additional module to perform bit interchange between two consecutive bytes. This bit interchange will take place before DJSSA method. The user has to enter some secret text-key
