Efficient implementation of 1024-Bit symmetric encryption protocol for low range devices

In today's world information security is a big issue everyone wants a network upon which their data remain secure but even on highly secure networks, there is chance of hacking especially in large organizations like banks so more secure network is needed. In this paper, data security is done by using only one key for encryption and decryption. Digital image have many pixels and each pixel have their own values. Each pixel has n (mean number of rows) and m number of column and it is presented as n∗m. whenever we allocated digital image over a network we consider two things source and destination on source side we can encrypt image to hide the image on the destination side and decrypt image on desitnation side. For this encryption and decryption, 1024 symetric algorithm is used.
