Summary: The proposed cryptosystem utilizes temporal skew Fourier transformers (TSFTs) to enhance security, which introduces complex-value modulations that increase the difficulty of phase retrieval attacks. Additional secret keys are generated by the skew coefficients epsilon(1,2) in the encryption stage, making the attack more challenging. The system's fidelity robustness against noise and occlusion on optical communication channels is also demonstrated.

Summary: In this research, a physically enhanced ghost encoding scheme is proposed by utilizing the optical channel characteristics and dynamically generated scaling factors as security keys. The dynamic scaling factors are controlled in the optical path to achieve physical enhancement of ghost encoding. The proposed method introduces a variable beam attenuator and an amplitude-only spatial light modulator (SLM) to generate dynamic scaling factors. Optical experiments are conducted to verify the feasibility and effectiveness of the proposed scheme, which could bring new research perspectives to optical ghost encoding.

Summary: This paper proposes an effective content-adaptive image compression and encryption method based on compressive sensing and double random phase encoding. The method converts the original image into low-frequency and high-frequency parts using DWT and sorts them using chaotic sequences. A novel measurement matrix optimization algorithm is presented to measure the high-frequency components. The security of the scheme is enhanced through DRPE, quantization, and diffusion. The encryption process utilizes the Logistic-Sine chaotic system to generate chaotic keystreams, providing effectiveness against known-plaintext and chosen-plaintext attacks. Numerical experiments demonstrate the effectiveness of the proposed algorithm.

Summary: In this paper, we propose a double image encryption approach based on a hybrid phase-truncation scheme. The proposed method utilizes spatial and Fresnel encoding to encrypt two plaintexts into two private key masks and one ciphertext mask. Compared with other phase-truncation techniques, this hybrid scheme not only prevents information leakage but also resists various types of attacks. The parameters of the Fresnel transform and discrete multiple parameter fractional Fourier transform serve as additional keys to enhance the security significantly.
