| contents | We introduce groundbreaking techniques in image encryption, assuming the existence of quantum computing ressources functioning with qudits, where d is a power of 2. Our quantum representation of color multi-image is based on space-filling curves and allows to reduce the storage space. We generalize the quantum baker map, so that it may scramble two n-qudits. By doing so, we enlarge its parameter space exponentially, leading to a better security. We define two new concepts of mixed scrambling and mixed diffusion, and present a variety of schemes, depending on the needs of the users. |
