High-dimensional discrete chaotic systems have a wide range of engineering applications, while the chaotic synchronization method is the key to confidential communication applications. Based on the proposed discriminant theorem for high-order polynomial chaotic mapping, in this paper, a hybrid inverse generalization and inverse projection synchronization method for high-dimensional discrete chaotic systems is constructed. The method increases the flexibility of synchronization control by designing to enable the coexistence of inverse projection synchronization and inverse generalized synchronization in chaotic systems, by specifically using an invertible and adjustable constant diagonal matrix to extend the control capability of the error system. Meanwhile, this paper proposed the validity of this hybrid synchronization scheme based on the multi-stationary chaotic system for the first time, through comparison, it is certified that the multi-stationary discrete chaotic synchronization system introduced in this paper not only has complex dynamics behavior but also has a faster synchronization speed. Meanwhile, this paper proposed the validity of this hybrid synchronization scheme based on the multi-stationary chaotic system for the first time, through comparison, it is certified that the multi-stationary discrete chaotic synchronization system introduced in this paper not only has complex dynamics behavior but also has a faster synchronization speed. Finally, a transmission system based on hybrid synchronization is also designed in this paper, where experiments and analyses of cryptographic transmission of pictures are carried out, and the results of the analyses show that the system has higher security and a larger key space.

“…The proposed algorithm is also tested against the known plaintext attack (KPA) [8], chosen plaintext attack (CPA) [9], and a special iterative attack [30]. Figure 11 presents the results for KPA and CPA when the grayscale 'Building' image is used as the original image.…”

“…Although these types of asymmetric cryptosystems can resist the known plaintext attack and the chosen plaintext attack, it has been found that they can be targeted by iterative cryptographic attacks [22,24]. The security of these cryptosystems was further enhanced by using different approaches, such as, integral transforms, polarization lights, ghost imaging, compressive sensing, joint transform correlator, ptychography, sparse representation, and photon counting [25][26][27][28][29][30][31]. Recently, some optical authentication techniques in conjunction with image encryption schemes have also been discussed, which can provide an additional layer of security to information transmissions [32].…”

In this paper, a new multiuser optical image encryption and authentication technique is proposed. Sparse multiplexing and polar decomposition are used in the Fresnel domain to obtain the ciphertext of an input image. To enable the multiuser platform, multiple private keys are obtained through polar decomposition during the encryption process. It will allow multiple authorized users to access the secure information simultaneously without having the key distribution problem among them. The proposed method has a large key space and robust against several attacks, such as, contamination attacks (noise and occlusion), brute force attack, plaintext attacks, and special iterative attack. A comparative analysis of the presented technique is also performed with the similar existing techniques. The numerical simulation results demonstrate the robustness and feasibility of the proposed algorithm.

“…In order to fulfill the security requirements, many encryption schemes have been proposed and analyzed as possible solution systems which include chaos [7]- [9], Scan [10], [11] and some other methods are available [12]- [15]. Each technique has their own merits and demerits in terms of pixel randomness of encoded image, key size, strength, security and size of input data.…”
