“…Rodrigo et al have derived the main properties of the GT [26], designed a setup to optically implement this transform [27] and presented several applications of the GT to image processing [7]. The GT has been utilized in image encryption with: RPMs generated by chaos [28], Arnold transform [29] and iterative random phase encoding [30,31,32], among other works.…”

Abstract.A novel nonlinear image encryption scheme based on a fully phase nonzeroorder joint transform correlator architecture (JTC) in the Gyrator domain (GD) is proposed. In this encryption scheme, the two non-overlapping data distributions of the input plane of the JTC are fully encoded in phase and this input plane is transformed using the Gyrator transform (GT); the intensity distribution captured in the GD represents a new definition of the joint Gyrator power distribution (JGPD). The JGPD is modified by two nonlinear operations with the purpose of retrieving the encrypted image, with enhancement of the decrypted signal quality and improvement of the overall security. There are three keys used in the encryption scheme, two random phase masks and the rotation angle of the GT, which are all necessary for a proper decryption. Decryption is highly sensitivity to changes of the rotation angle of the GT as well as to little changes in other parameters or keys. The proposed encryption scheme in the GD still preserves the shift-invariance properties originated in the JTC-based encryption in the Fourier domain. The proposed encryption scheme is more resistant to brute force attacks, chosen-plaintext attacks, known-plaintext attacks, and ciphertext-only attacks, as they have been introduced in the cryptanalysis of the JTC-based encryption system. Numerical results are presented and discussed in order to verify and analyze the feasibility and validity of the novel encryption-decryption scheme.

“…It has been extended to allow other transforms take the place of the optical Fourier transform, such as the Fresnel transform [5] (including by means of a chirp placed in the Fourier plane [6]), fractional Fourier transform [5], [7], and the 1-dimensional linear canonical transform (1D-LCT) [8]. Phase retrieval based on intensities captured in planes related by one specific nonseparable transform, the gyrator transform, have also been reported [9], [10], [11], [12], [13], [14], [15]. The advantage of using these alternative systems is that increased flexibility for the system designer.…”

This paper proposes a novel ARX model-based image encryption scheme that uses addition, rotation, and XOR as its confusion and diffusion mechanism instead of S-Box and permutation as in SP networks. The confusion property of the proposed scheme is satisfied by rotation and XOR with chaotic sequences generated from two logistic maps. Unlike classical image encryption schemes that adopt S-Box or permutation of the entire plain image, the diffusion property is satisfied using addition operations. The proposed scheme exhibits good performance on correlation coefficients (horizontal, vertical and diagonal), Shannon's entropy and NPCR (Number of Pixels Change Rate). Furthermore, simulation results indicate that its time complexity is 9.2 times more efficient than the fastest algorithm(Yang's algorithm).
