Wei-Dong ZHU, Meng-Zhen CUI · 2018
The traditional encryption technology mainly relies on computer or digital signal processor and other electronic devices to achieve, so the speed and cost were restricted.As a result, people began to study more secure and efficient quantum image encryption technology.In this paper, a new method of quantum image encryption based on Arnold transform and hyperchaotic system is proposed.The encryption process of this paper consists of two phases: scrambling encryption stage and gray scale encryption stage.In this paper, a quantum image encryption algorithm based on hyperchaotic system is adopted in the gray scale encryption stage.The hyperchaotic system is used to generate hyperchaotic sequences, which are used to control non-operation.Theoretical analysis and classical numerical simulation show that this new method of quantum image encryption based on Arnold transform and hyperchaotic system has good security and anti -attack.
