In the digital era, image encryption security is a focus. Facing security risks such as the irrelevance of plaintext and ciphertext and the independence of the disarrangement and diffusion steps, a new algorithm combined with a chaotic Hopfield neural network is proposed. The algorithm synchronizes the scrambling and diffusion to enhance its security. By associating the initial value of the network with the plaintext image, the algorithm not only improves the defense capability against chosen plaintext attacks and known plaintext attacks but also enhances the sensitivity of the key. Experimental data highlights its excellent performance, as the encryption algorithm effectively defends against attacks based on statistical information when 10,000 pairs of randomly selected adjacent pixel points with different orientations are analyzed. Meanwhile, the differential attack analysis exhibits high scores of 99% and 33% in the pixel change rate and uniform average change intensity, which are close to the theoretical optimal values. In addition, the average values of the RGB channels are 254.8, 261.5, and 256.9, respectively, which are lower than the pre-calculated theoretical value of 293.24783, further confirming its excellent security and concealment. This study is an important contribution to enhancing security. © (2025), (International Journal of Network Security). All rights reserved.

With the rapid development of the internet and information technology, the traditional encryption methods suffer from drawbacks such as poor processing capacity and low security, making them vulnerable to attacks. This paper presents a hybrid encryption algorithm that combines the Lorenz chaotic system and the generalized Arnold transform to enhance information security and confidentiality in digital images. The proposed quantum encryption scheme involves two stages: interfering with pixel coordinate information and grayscale values using the generalized Arnold transform, followed by spatial domain scrambling of pixel positions using the Lorenz chaotic system. MATLAB simulations demonstrate the effectiveness of this algorithm in achieving the desired confusion and diffusion of pixel values, making it a superior encryption method for cryptography. © 2025 SPIE.

The increasing necessity for secure communication in resource-constrained platforms those found in the Internet of Things (IoT), has drawn to a key spike in demand for lightweight symmetric cyphers. However, a number of numerous algorithms and implementation are available and, selecting the best security solution for a given application is still difficult. The implementation of Lightweight Advanced encryption Standard (LAES) algorithms on hardware is the main concern of this work which will be suited for the IoT devices. In this work LAES is implemented to satisfy the security requirements for the IoT devices. Kintex 7 FPGA (Field Programmable Gate Array) is used for the implementation, and key performance metrices including hardware area utilization are used to assess the performance. The results determine prominent improvements in accomplishing compact, area-efficient designs. There is a decrement of 73.10% in LUT consumption as compared with exiting approaches. © 2025 IEEE.

With the rapid advancement of cloud computing, significant security concerns regarding data storage have been continuously raised. When the encrypted images are stored in the cloud, reversible data hiding in encrypted domain is used to embed additional data to manage the storage resources in the cloud. Most of the current works are applied to uncompressed images rather than JPEG images. Therefore, this paper proposes a reversible data hiding algorithm for JPEG images based on an enhanced Paillier homomorphic encryption algorithm. In the proposed scheme, the AC coefficients are altered by using a ciphertext distribution constrained paillier homomorphic encryption algorithm, so as to reduce the size of the data-embedded encrypted image. Whereas, the DC coefficients are encrypted by using the one-dimensional tangent chaos encryption algorithm, thereby ensuring high security of the encrypted image. Moreover, according to the characteristics of the homomorphic encryption algorithm, the confidential data can be recovered from both the encryption domain and from the plain domain. Experimental results demonstrate that the ciphertext distribution-constrained Paillier homomorphic encryption algorithm obtains higher data embedding capacity and superior security in comparison with other advanced algorithms. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

This paper introduces a new encryption technique which bases its operations on advanced bivariate mathematical functions and uses a genetic algorithm to optimize these along with random key generation techniques. This, in turn, allows for the enhancement of cryptographic complexity and better security features with fortified protection against any possible attacks. The encryption mechanism integrates random keys along with the evolved bivariate functions, and RSA protocol is employed for securing the channel of exchanging keys, ensuring confidentiality at each stage of the transmission process. The integration of these methodologies has created a two-layer security framework that combines the efficiency of symmetric encryption with the robustness of RSA. Advanced symmetric encryption combined with RSA significantly increases the security measures provided by defending against brute force attacks, cryptanalysis, and intercept threats. Through the combination of symmetric encryption and an asymmetric key exchange protocol, this strategy fully addresses the disadvantages of the typical cryptographic system. It forms an effective solution in meeting the contemporary security demands for digital communication environments. © 2025 IEEE.

Patterns are key to decrypting messages. Language is composed of repeat groupings of symbols encoded in words and the syntax of a language. Patterns bleed through encryption since all encryption algorithms can be replaced by a substitution (S) cipher. This makes it possible to analyze the patterns in cipher text using the collisions in the cipher text message. Each language has its own unique lexicon and rules, making it possible to identify both the original plain text language and the size of the block used for encryption. The ability to identify this data supports both Kerckhoffs' and Shannon's assumption that the attacker knows all of the important data about the encryption algorithm, minus the secret key. In practice, this means that an attacker can quickly focus on the data needed to prosecute an attack on an encrypted message just by analyzing collisions in the message. This paper demonstrates that such an approach is feasible and lays the foundation to explore how to derive the information needed to attack encrypted messages using data from the collisions in the cipher text. © 2025 IEEE.

In view of the problems of small key space and poor key sensitivity in classical image encryption algorithm, the characteristics of chaotic system and M set are analyzed, and a new image encryption algorithm is proposed in this paper. The parameter values generated by SHA-256 algorithm are substituted into the hyper-chaotic Lorenz system to form the initial values of the input plaintext image. Then pseudo-random sequences are generated by hyper-chaotic Lorenz system, and the sequences are scrambled and diffused. The image matrix is generated according to Mandelbrot set, and the image is scrambled again with the sequence generated by different iteration times, and the encrypted image is finally obtained by XOR operation. The experimental results show that the proposed image encryption algorithm has good performance in various evaluation criteria, the key space value of the algorithm is large enough, high key sensitivity and the correlation of adjacent pixels is significantly reduced, and the information entropy is close to the ideal value. Thus this paper proposes image encryption algorithm has good security, can satisfy the requirements of the digital image encryption technology. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

Quantum Key-Revocable Dual-Regev encryption, Revisited 22nd

Quantum Key-Revocable Dual-Regev Encryption, Revisited

Quantum information can be used to achieve novel cryptographic primitives that are impossible to achieve classically. A recent work by Ananth, Poremba, Vaikuntanathan (TCC 2023) focuses on equipping the dual-Regev encryption scheme, introduced by Gentry, Peikert, Vaikuntanathan (STOC 2008), with key revocation capabilities using quantum information. They further showed that the key-revocable dual-Regev scheme implies the existence of fully homomorphic encryption and pseudorandom functions, with both of them also equipped with key revocation capabilities. Unfortunately, they were only able to prove the security of their schemes based on new conjectures and left open the problem of basing the security of key revocable dual-Regev encryption on well-studied assumptions. In this work, we resolve this open problem. Assuming polynomial hardness of learning with errors (over sub-exponential modulus), we show that key-revocable dual-Regev encryption is secure. As a consequence, for the first time, we achieve the following results:Key-revocable public-key encryption and key-revocable fully-homomorphic encryption satisfying classical revocation security and based on polynomial hardness of learning with errors. Prior works either did not achieve classical revocation or were based on sub-exponential hardness of learning with ***-revocable pseudorandom functions satisfying classical revocation from the polynomial hardness of learning with errors. Prior works relied upon unproven conjectures. Key-revocable public-key encryption and key-revocable fully-homomorphic encryption satisfying classical revocation security and based on polynomial hardness of learning with errors. Prior works either did not achieve classical revocation or were based on sub-exponential hardness of learning with errors. Key-revocable pseudorandom functions satisfying classical revocation from the polynomial hardness of learning with errors. Prior works relied upon unproven conjectures. © International
