Image Encryption Using Random Permutation by Different Key Size

Security of information is main aspect in network communication. The information may be in the form of text, voice and multimedia (image and video). In new generation of technology peoples transmit images over an open network which is need to be secure. There are various encryption methods to secure image from unauthorized parties. In this paper, image is encrypted using different combination random permutation techniques. A digital image can be represented by two dimensional arrays which have numeric value called pixel and a pixel is collection of bits.
