During recent decades, double random phase encoding grasped more attention for researchers. To achieve nonlinearity, it had been done with random S-Box. We exhibit this involvement that DRPE system is much vulnerable in the above methodology. Concatenating anything with DRPE needs an imaginary value, wherein s-box unsuccessful in it. Used S-box has been reformed into various sizes. Due to this scenario, S-box values are replicating. So, complex S-box has been employed and proposed size of the s-box is similar to an input image. Numerical simulations have been performed out to validate the practicability and trustworthiness of traditional DRPE system with complex S-box.

“…However, the computation more complicated and the security levels are low in chaos theory based ciphering algorithms [17]. Other ciphering algorithms were proposed based on decomposition techniques [15], [18]- [21]. However, the drawbacks of those techniques were the security levels rustiness because of the bit planes numbers and its contents are constant in additive to key space were little.…”

<span>Image security is still one of the important fields in multimedia processing because it’s used in our daily lives. Watermarking, steganography, and ciphering are three directions to keep an image secret. Encryption defined as the process of changing information (which called plaintext) into an unreadable secret format (which called cipher-text). A new ciphering algorithm based on binary decomposition and binary codes conversion is proposed in this paper. The key is constructed in a flexible way based on the size of a secret image using some logical operations to increase the security levels. Three test images in different sizes were used to evaluate the performance of the proposed algorithm. The results of the visual scene and statistical factors proved that the suggested method was ciphering the image with high security. The proposed work was validated to confirm its effectiveness. As conclusions, the uses of decomposition and simple binary operations have given high-level image security. Also, key construction is an important step to face several types of attackers.</span>

“…In 2020, Abdelfattah et al [34] proposed a compact optical asymmetric encryption system for multicolor images without contours based on unequal modulus decomposition (UMD) in the GT domain. Asymmetric optical cryptosystem using lower upper (LU) decomposition is proposed in light of FrFT [35], an asymmetric image encryption mechanism using QR decomposition in hybrid multi-sesolution wavelet domain [36], a single-channel color information security system using LU decomposition in GT domain [37]. Further the cryptosystem is extended to use LUDPP [38].…”

An asymmetric optical cryptosystem to encrypt images using devil's vortex Fresnel lens (DVFLs) phase masks and lower upper decomposition with partial pivoting (LUDPP) is proposed in gyrator transform domain. The proposed cryptosystem utilizes DVFLs which are the complex phase masks designed using the combination of a phases of devil's lens (DL), vortex lens(VL), and Fresnel lens (FL). LUDPP is an operation used to decompose the matrix and is utilized to supersede the phasetruncation (PT) task in the traditional phase-truncated Fourier transform (PTFT). Hence, the proposed method is immune to the attacks to which the PTFT-based cryptosystems are vulnerable. The cryptosystem is asymmetric as both the encryption and decryption processes are different along with different keys. The private keys generated during the encryption process are utilised in the decryption process to retrieve the original image. The encryption and decryption process can be realised with both the digital and the modified optical architecture. In order to show the strength and robustness of the proposed encryption, a conspire numerical simulation was performed.
