Facing the threat of quantum computing to cryptography schemes, it is urgent to study the applications of quantum algorithms to cryptanalysis and evaluate the security of cryptographic schemes in a quantum computing environment. To do this, it is necessary to analyze the ability of cryptanalysis methods, such as integral and linear attacks, when combined with quantum algorithms. In this article, we investigate the properties of block ciphers with SPN structure and their security against a quantum adversary and apply the Bernstein-Vazirani algorithm to zero correlation linear attacks. Based on the relation between linear approximates of SPN ciphers and the dual cipher's linear structures, we proposed a quantum algorithm that can find linear hulls with zero correlation of SPN ciphers. We show the validity of the proposed quantum algorithm and estimate the corresponding computational complexity. Implementing our quantum algorithm only costs polynomial qubits and quantum gates. © Published under licence by IOP Publishing Ltd.

Comfy records transmission is a crucial generation in the data safety area. It entails the use of cryptographic algorithms to secure statistics in order that it cannot be accessed without authorization. Cryptography algorithms are carried out to secure the data to defend it from theft, malicious right of entry, and disclosure. Examples of carried-out algorithms encompass symmetric-key encryption, public-key encryption, digital signatures, message authentication codes, and hash capabilities. These algorithms are used for diverse functions, consisting of authentication, encryption, and integrity. Symmetric-key encryption is used to securely speak among events without the want for a 3rd-party intermediary. Public-key encryption is used to signal facts for evidence of integrity and authenticity digitally. Message authentication codes and hash functions are used to confirm that facts have not been changed or tampered with in transit. These cryptographic algorithms are key to providing security in records transmission as they make sure of comfy verbal exchange and help save you unauthorized access. ©2024 IEEE.

The Internet of Things (IoT) becomes the most demanding technology over the past few years. IoT is the basic need of daily life. The security of these devices is very important because they contain large files of sensitive data, the exposure of these devices can be fatal. To ensure the security of different types of IoT devices, we have designed a problem for optimization of weights in this work. The operational goal of this work is to protect different IoT devices alogwith determining a balance between resource and device usage. This framework includes resources and transfers the requirements of heterogeneous IoT devices and modifies different image and implementations using Hungarian algorithm. To attain the objective, five different ways are described to solve the Advanced encryption Standard (AES). Extensive testing is done to find the best trade with different stocks and weights. The proposed framework is also compared to random greedy methods. The benchmark results show that the proposed system has been modified to secure the system based on IoT while offering better performance and results. Compared to the random method, the proposed method yielded an average of 3% and 13% improvement and in 11% and 17% greedy approach and resource utilization. © 2024 IEEE.

2024 International Conference on Information Technology Systems and Innovation, ICITSI 2024

In this paper, we review lightweight security approaches for resource-constrained IoT devices. Previous research has explored various lightweight cryptographic algorithms, such as PRESENT, PRIDE, SNOW-V, and ChaCha20 ciphers, which aim to optimize security while minimizing computational overhead. Other research on intrusion detection systems (IDS) and authentication frameworks tailored to IoT environments have also been proposed, focusing on adaptability and reducing performance impact on low-power devices. Despite significant progress, critical gaps remain in integrating lightweight cryptographic techniques with AI-based anomaly detection and blockchain-based data integrity mechanisms. This paper identifies and analyzes these gaps, proposing a hybrid approach that combines lightweight encryption with AI-based key management to address these challenges, thus offering an option for a more robust yet efficient security framework for IoT networks. The proposed approach aims to increase scalability and flexibility while maintaining low power consumption and a high level of security. By comparing existing research and identifying emerging gaps, this research is expected to provide new solutions that bridge the limitations of existing lightweight security frameworks. © 2024 IEEE.

This study introduces an innovative approach to enhancing AES-256 encryption by integrating the Keccak permutation into its key generation process, aiming to improve both security and performance while reducing the number of encryption rounds. Keccak-enhanced AES-256, evaluated with 10 and 14 rounds, was compared against the standard AES-256 (14 rounds) across key metrics such as entropy, avalanche effect, differential probability, encryption time, power consumption, and side-channel attack resistance. The 10-round Keccak-enhanced variant achieved a 25% reduction in encryption time and a 28% decrease in power consumption compared to standard AES-256, while maintaining a high avalanche effect (95%) and significantly lower differential probability (10^-9), indicating enhanced security. The results suggest that Keccak-enhanced AES-256 provides a more efficient and secure alternative to traditional AES-256, with significant implications for security-critical applications in finance, healthcare, and government sectors. By setting a new standard for encryption efficiency, this approach paves the way for future research into optimizing cryptographic algorithms for various real-world scenarios. © 2024 IEEE.

Secure fiber-optic communication systems are an important area of research and development in the IT industry. In this work, we report the development of a promising fiber laser system for physical-layer secure key generation and distribution. This is a pulsed ultra-long Erbium fiber laser in which pulse shaping is symmetrically split between two communicating parties (Alice and Bob). The proposed protocol for the physical-layer secure key generation and distribution is based on control of the duration of generated laser pulses. Alice and Bob contribute random binary values to the secure key generation by making independent choices of their states in the split pulse shaping every bit cycle. The key exchange is secured whenever different choices lead to the same pulse duration, thereby confusing an eavesdropper (Eve). Two strong algorithms for the transmitted data encryption at the physical layer are proposed and discussed as well. One of them uses a private key to encrypt the message entered by one of the communicating parties, and the other uses a meaningful message entered synchronously by the other party. © 2024 IEEE.

This paper explores the performance of implemented cryptography algorithms used for various blockchain technologies, which include Bitcoin, Ethereum, and Hyperledger. Diverse techniques for assessing cryptographic algorithm implementations and their relative performances are mentioned, inclusive of efficiency (variety of bits processed in step with unit time), strength intake, and hardware overhead. Through studying the computational complexity, conversation complexity, and garage ability, the paper assesses commonplace operations together with key era, key alternate, virtual signature, and encryption/decryption for a ramification of algorithms. Further, the scalability of the algorithms on big networks is tested and analyzed. ultimately, an assessment of the security of the algorithms is executed by measuring security parameters, which include facet-channel assault resistance, nonce reuse resistance, and quantum resistance. This paper provides an overview of the overall performance of applied cryptography algorithms, which allows researchers and developers to pick out the algorithm that is most appropriate for their blockchain utility. ©2024 IEEE.

This paper proposes a blockchain privacy encryption scheme based on CRT-RSA algorithm. This encryption scheme decomposes the large integer modular operation of RSA algorithm into two smaller modular operations, which significantly improves the computational efficiency. Through the comparison of random decryption experiments, it is confirmed that the improved algorithm im-proves the efficiency and the results are more stable. The experimental results verify the feasibility of this encryption scheme in solving the problem of privacy processing efficiency of blockchain big data. © 2024 IEEE.

In OFB mode, the output of the cryptographic algorithm is fed back to the input of the cryptographic algorithm. The OFB mode does not directly encrypt plaintext through cryptographic algorithms, but generates ciphertext blocks by XOR combining plaintext blocks with the output of cryptographic algorithms. In OFB encryption mode, messages are treated as bitstreams, and the output of block encryption is added to the encrypted messages, making it difficult for bit errors to propagate. The SM4 algorithm is a symmetric cryptographic technique developed by the Chinese National Cryptographic Administration and standardized as part of the State encryption Standard in China. SM4 is widely adopted in various applications, including wireless communication systems and secure data transmissions. In this paper, a fast implementation method of SM4 in OFB mode is proposed. We calculate the possible parallelization operations in OFB mode using the operational relationship between the SM4 algorithm round functions, and ensure the correctness of SM4-OFB encryption through a feedback compensation method. © 2024 IEEE.

Radical (formula presented) Isogeny Formulae 44th

Radical (formula presented) Isogeny Formulae

引用

44th Annual International Cryptology Conference, CRYPTO 2024

作者： Decru, Thomas Université Libre de Bruxelles Bruxelles Belgium

ISBN: (纸本)9783031683879

We provide explicit radical N-isogeny formulae for all odd integers N. The formulae are compact closed-form expressions which require one Nth root computation and O(N) basic field operations. The formulae are highly efficient to compute a long chain of N-isogenies, and have the potential to be extremely beneficial for speeding up certain cryptographic protocols such as CSIDH. Unfortunately, the formulae are conjectured, but we provide ample supporting evidence which strongly suggests their correctness. For CSIDH-512, we notice an additional 35% speed-up when using radical isogenies up to N=199, compared to the work by Castryck, Decru, Houben and Vercauteren, which uses radical isogenies up to N=19 only. The addition of our radical isogenies also speeds up the computation of larger class group actions in a comparable fashion. © International Association for Cryptologic Research 2024.
