Abstract

The optical image encryption and decryption method based on compound chaos and quantum chaos involves the field of optical information security technology, and solves the security defects of the existing optical image encryption technology due to the non-linearity, including the encryption process and decryption process, and separately sets the user encryption key and The decryption key is composed of the initial value, control parameters, and order of the hyperchaotic system of the three-cell fractional order quantum cellular neural network; the initial value, control parameters, and series of deformation fractional Fourier transform of the composite chaotic map; the present invention It makes up for the security defects of the traditional optical image encryption technology with insufficient linear features, and the fractional order quantum chaos system has a higher key dimension, a larger key space, stronger sensitivity, and a better ability to resist various security attacks. Strong, and because the quantum chaotic system is a new type of nanoscale device that transmits information to each other through Coulomb interaction between quantum dots and quantum cellular automata, it has the advantages of ultra-high integration, low power consumption, and lead-free integration.

Description

technical field [0001] The invention relates to the technical field of optical information security, in particular to an optical image encryption and decryption method based on fractional order quantum chaos and deformed fractional Fourier transform Background technique [0002] With the rapid development of optical technology and information technology, optical information processing technology has made great progress. The inherent parallel processing capability of the optical information system shows incomparable advantages in the processing of massive amounts of information. Since the dual random phase optical encryption technology was first proposed in 1995, researchers have designed a large number of dual random phase optical image encryption method. Optical image encryption technology has strong parallel processing capability, and optical parameters can also be used as user keys to increase the key space, so optical image encryption technology has been widely used.
