A real-time video encryption module, developed to be used on an electrical accelerated mini-helicopter (UAV), is presented in this paper. The surveillance system is composed from six modules: image capture, encryption, two radio link modules, dec

The number of changing pixel rate (NPCR) and the unified averaged changed intensity (UACI) are two most common quantities used to uate the strength of image encryption algorithms/ciphers with respect to differential attacks. Conventionall
