According to the scrambling and encryption processing steps, in the embodiment, taking an M × N image as an example, a quadruple key is adopted when the Rossler transformation is used, so that the security of scrambling is increased. The Rossler transform scrambling algorithm mainly comprises the following steps:
step1, reading a graph Image to be scrambled, wherein the size of the graph Image is M x N, determining a first secret key k = u (scrambling times), and establishing a temporary matrix B, wherein the size of the matrix B is the size of the graph Image;
