Measurement of Encryption Quality of Bitmap Images with RC6, and two modified version Block Cipher by Baedaa H. Helal, Ashwaq T. Hashim

“…Due to the increasinguse of images in industrial process, it is essential to protect the confidential imagedata from unauthorized access. In this paper, RC6 with two modified version 512bit RC6 and 640 bit RC6-Cascade encryption algorithms will be analyzed toinvestigate the encryption efficiency for them to digital images and providing anew mathematical measure for encryption efficiency. …”
