Binay Kumar Singh, Sudhir Kumar Gupta . Grid-based Image Encryption using RSA. International Journal of Computer Applications. 115, 1 ( April 2015), 26-29. DOI=10.5120/20116-2166
In recent years, security of several kinds of images is a major issue in secure data communication over any unreliable network. In this paper, a new technique to secure images by using grid-based encryption and decryption approach with RSA cryptosystem has been devised. This approach has taken original image, performed block transformation followed by grid transformation, then finally a public key cryptosystem is applied pixel-by-pixel to secure image. Experimental images have been taken and performed encryption and decryption to elaborate this technique. Error analysis shows that the technique is robust.
