A New Measurement for Image Encryption Effect
LI Luo-luo · Acta Scientiarum Naturalium Universitatis Sunyatseni · 2005
With the development of digital image enciphering techniques, there appeared a lot of methods including those based on Arnold transformation and affine transformation and those based on theories of Hilbert curve, Knight_tour problem and Gray code,etc. However , there are few criteria to measure the merits and demerits of these methods. In this paper some new criteria are provided to formulate the effect of existent enciphering methods. Experiments show that these criteria can also be used to measure the relationship between the enciphering effect and the number of iterations in the enciphering techniques.
