In the ever-expanding landscape of the Internet of Things (IoT), safeguarding the security and privacy of data transmissions among IoT devices has become increasingly critical. This research introduces an innovative approach known as "Chaotic Resilience" to bolster the security of data exchanged between IoT devices. While traditional encryption methods are effective, they often rely on fixed cryptographic keys, making them susceptible to attacks over time. Chaotic Resilience introduces an element of dynamic unpredictability into the encryption process, making it considerably more resistant to brute-force attacks and key extraction techniques. The proposed technique involves the integration of chaotic systems, such as the 4D chaotic map, into the encryption process. These chaotic systems generate an ongoing sequence of unpredictable values, which are then combined with the plaintext data through a dynamic encryption algorithm. The result is ciphertext that becomes highly sensitive to initial conditions and practically immune to standard cryptographic attacks. Moreover, the dynamic nature of the encryption process ensures that even if an attacker gains access to the encryption algorithm, they cannot predict future encryption keys. Through extensive simulations and experiments, we demonstrate the effectiveness of Chaotic Resilience in thwarting various attack scenarios, including brute-force attacks, chosen-plaintext attacks, and known-plaintext attacks. Additionally, Chaotic Resilience demonstrates a 20% increase in encryption speed and a 15% reduction in resource utilization, establishing it as an efficient and robust IoT security solution. Our results underscore that Chaotic Resilience significantly enhances the security and resilience of IoT data transmissions, offering a promising avenue for strengthening IoT security in an increasingly interconnected world. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

This paper presents a technique for ensuring secure communication between interconnected devices using the Serial Peripheral Interface (SPI) protocol. The method combines the strengths of the Physical Unclonable Function (PUF) and the SHA-256 Hashing Algorithm to generate an exceptionally secure key that is nearly impossible to decode, thereby preserving the internal security of the embedded nodes. The data transmitted through the channel is encrypted using the Blowfish symmetric key encryption algorithm. A new unique key is generated for each channel, guaranteeing enhanced security. The proposed algorithm provides robust protection against various attacks that target the encryption key and system integrity. Furthermore, the algorithm is implemented in hardware to evaluate its effectiveness, identify areas for improvement, and optimize its functionality. Through this hardware implementation, the authors assess the technique’s performance and explore potential enhancements for its future development. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

In order to solve the problem of researching the distribution of returns on trustworthy "dual contribution" data assets, the authors propose a research on the distribution mechanism of returns on trustworthy "dual contribution" data assets based on blockchain technology. Integrate and apply various levels in the blockchain system. In this model, a node authorization control mechanism is added in the network layer, which can be customized in the consensus layer, and the data query efficiency can be improved through the optimization of the structure and the establishment of the index, so that the data can be managed intelligently in the intelligent contract layer, and encrypts information with customizable encryption algorithms at the transaction layer. In simpler terms, the new data asset management model utilizing blockchain technology has made on-chain data queries 2.25 times faster compared to conventional models. The benefit distribution mechanism model of blockchain is more conducive to internal cooperation than the traditional model. © (2025), (West University of Timisoara). All rights reserved.

An Interpolated Quantized Guard Band Algorithm for Physical Layer Key Generation

Intelligent and Converged Networks 2025年第1期6卷 102-114页

With the continuous progress of communication technology, traditional encryption algorithms cannot meet the demands of modern wireless communication security. Secure communication based on physical layer encryption emerges as a solution. To meet the low Key Disagreement Rate (KDR) and high Key Generation Rate (KGR) requirements for physical layer key generation, this paper proposes two quantization algorithms, Improve-CQG and Interpolate-CQG, based on the Channel Quantization with Guard band (CQG) algorithm. The former divides the characteristic quantization into two phases: threshold filtering and guard band quantization, while the latter adds a step after these two phases: interpolation quantization. Compared to the CQG algorithm, the Improve-CQG algorithm enhances the granularity of filtered quantization values. The core concept of the Interpolate-CQG algorithm is to utilize threshold filtering and the rounded-off quantization values from the guard band quantization phase. The symbol information corresponding to these index values is replaced by a new interpolated symbol and inserted into the key by the agreed quantized coordinates. Simulation proves that the Interpolate-CQG is an effective quantization algorithm for the key generation with lower KDR and higher KGR than the Improve-CQA and Improve-CQG. © 2020 Tsinghua University Press.

Unbounded ABE for Circuits from LWE, Revisited 30th

Unbounded ABE for Circuits from LWE, Revisited

引用

30th International Conference on the Theory and Application of Cryptology and Information Security

ISBN: (纸本)9789819608935;9789819608942

We introduce new lattice-based techniques for building ABE for circuits with unbounded attribute length based on the LWE assumption, improving upon the previous constructions of Brakerski and Vaikuntanathan (CRYPTO 16) and Goyal, Koppula, and Waters (TCC 16). Our main result is a simple and more efficient unbounded ABE scheme for circuits where only the circuit depth is fixed at set-up;this is the first unbounded ABE scheme for circuits that rely only on blackbox access to cryptographic and lattice algorithms. The scheme achieves semi-adaptive security against unbounded collusions under the LWE assumption. The encryption time and ciphertext size are roughly 3x larger than the prior bounded ABE of Boneh et al. (EUROCRYPT 2014), substantially improving upon the encryption times in prior works. As a secondary contribution, we present an analogous result for unbounded inner product predicate encryption that satisfies weak attribute-hiding.

In this paper, we describe an algorithm to compute chains of (2, 2)-isogenies between products of elliptic curves in the theta model. The description of the algorithm is split into various subroutines to allow for a precise field operation count. We present a constant time implementation of our algorithm in Rust and an alternative implementation in SageMath. Our work in SageMath runs ten times faster than a comparable implementation of an isogeny chain using the Richelot correspondence. The Rust implementation runs up to forty times faster than the equivalent isogeny in SageMath and has been designed to be portable for future research in higher-dimensional isogeny-based cryptography.

Currently, protecting personal privacy through selective encryption of facial images has become a research hotspot. This paper aims to design a new image encryption scheme using chaotic systems, optimization algorithms, and the Semi-Tensor Product (STP) theory. Firstly, we proposed a 3D Coupled Ikeda Map with Bounded Amplitude (3D-CIMBA), which has controllable Lyapunov exponents and high-complexity. Secondly, Particle Swarm Optimization (PSO) algorithm is used to generate control keys of the chaotic system, and produce chaotic sequences. Then, DeepFace model is applied to recognize facial regions for encryption. Moreover, the face image is encrypted by performing row-column alternation cyclic shifting operation and STP diffusion. Finally, cryptographic analysis is conducted using histograms, pixel correlation, information entropy, and SSIM. The simulation results show that this scheme demonstrates robustness against differential attacks and noise attacks, which also exhibits fast encryption speed and large key space. These results show that the proposed algorithm can encrypt facial information more efficiently and securely compared to traditional algorithms. © 1991-2012 IEEE.

Cryptography is a cornerstone of power grid security, with the symmetry and asymmetry of cryptographic algorithms directly influencing the resilience of power systems against cyberattacks. Cryptographic algorithm identification, a critical component of cryptanalysis, is pivotal to assessing algorithm security and hinges on the core characteristics of symmetric and asymmetric encryption methods. A key challenge lies in discerning subtle spatial distribution patterns within ciphertext data to infer the underlying cryptographic algorithms, which is essential for ensuring the communication security of power systems. In this study, we first introduce a plaintext guessing model (SCGM model) based on symmetric encryption algorithms, leveraging the strengths of convolutional neural networks to evaluate the plaintext guessing capabilities of four symmetric encryption algorithms. This model is assessed for its learning efficacy and practical applicability. We investigate protocol identification for encrypted traffic data, proposing a novel scheme that integrates temporal and spatial features. Special emphasis is placed on the performance of algorithms within both symmetric and asymmetric frameworks. Experimental results demonstrate the effectiveness of our proposed scheme, highlighting its potential for enhancing power grid security. © 2025 Hao et al.

This paper uses reconfigurable hardware (Field-Programmable Gate Array (FPGA) board) for security implementation, which has less complexity, more flexibility, and yields more efficiency. The Data encryption Standard (DES) was the earlier security algorithm for hardware execution, but computers with computational growth can break security in seconds. The Advanced encryption Standard (AES) overcomes the disadvantages of DES by providing more excellent protection with 128, 192, and 256 keys. AES is resistant to attacks and is optimized and power-effective. The paper implements 256-bit key-based AES for 128-bit data on Kintex ultrascale and Virtex 7 FPGA boards. Simulation results show that the Kintex ultra-scale implementation has fewer lookup tables (LUTs), registers, global buffers, bonded IOBs, and flip-flop pairs than the Vertex-7 boards. Additionally, the AES algorithm on the Kintex ultra-scale has less area usage and path delay than the Vertex-7 boards. © 2025 Informa UK Limited, trading as Taylor & Francis Group.
