Sorry, Dhayanithi Govindasamy, the steps you posted could easily have been extended past 56 bits key space, and so we are not permitted to host that discussion here due to US law.

Images are not always 0 to 255. For example CT scan images are routinely int16 values, -32768 to +32767

I'm guessing you did not do a search of the File Exchange or you would not be asking this. Please click on this link: http://www.mathworks.com/matlabcentral/fileexchange/index?utf8=%E2%9C%93&term=encryption

I need a algorithm written in Matlab, for a Elgamal encryption which can encrypt and decrypt data stream of 32 words, with a key which has a modulus of 1024 vits

Even US universities need to get approval to do research into advancing the state of the art in encryption. Note that encryption is different than encoding, like encoding a video into a binary file.

It is a frustrating restriction, and often makes little sense, but it is the law of the USA.
Another note: authentication is considered to be different than encryption. So something like a well-hidden watermark to verify copyright is legal. The technologies for watermarking are essentially the same as steganography (hiding messages), so the legal boundaries are far from clear.

Any algorithm that can encrypt binary streams can be used to encrypt images.
Discussion of all the image encryption algorithms and their benefits and tradeoffs is beyond the scope of this resource.
