Description

technical field [0001] The invention relates to a system capable of generating chaotic flow and its circuit realization, in particular to a generalized Sprott-A system with three-dimensional 2×2×1 cluster conservative chaotic flow and its circuit realization. Background technique [0002] Chaos encryption is a new subject in the field of image encryption. With the in-depth study of chaos theory, image encryption technologies based on chaotic systems continue to emerge. The existing chaotic encryption technologies can be divided into: chaos masking, chaos parameter modulation, chaos expansion frequency, chaotic keying. However, most of these chaotic systems applied to encryption are dissipative chaotic systems. Because the dissipative system has chaotic attractors and other reasons, the attacker can reconstruct the phase space by stealing a small sequence of the chaotic sequence, so as to achieve deciphering. Security risks. Conservative chaotic systems have no attractors i...
