Homomorphic encryption (HE) allows computations to be directly carried out on ciphertexts and is essential to privacy-preserving computing, such as neural network inference, medical diagnosis, and financial data analysis. Only addition and 2-input multiplication are defined over ciphertexts in popular HE schemes. However, many HE applications involve non-linear functions and they need to be approximated using high-order polynomials to maintain precision. To reduce the complexity of these computations, this paper proposes 3-input ciphertext multiplication. One extra evaluation key is introduced to carry out the relinearization step of ciphertext multiplication, and new formulas are proposed to combine computations and share intermediate results. Compared to using two consecutive 2-input multiplications, computing the product of three ciphertexts utilizing the proposed scheme leads to almost a half of the latency, 29% smaller silicon area, and lower noise without scarifying the throughput.

Data security aims to achieve confidentiality, integrity, and availability of data. To reach confidentiality, different encryption algorithms are needed. The most used today are RSA, AES, and Diffie-Helman. Although these algorithms are considered secure today, as the performance of computers increases, their security is radically reduced. Concerning the increasing performance of modern computers and the effort to use encryption algorithms in devices with limited memory, new encryption algorithms are being developed. Although post-quantum encryption algorithms are considered the most promising direction in this area, some scientists are also dealing with mutations of encryption algorithms. In this article, we deal with the design of two simple encryption algorithms - Vigener's cipher and matrix encryption. Next, we test these algorithms from the point of view of time requirements. © 2024 IEEE.

Algebraic Attack on LCB and Improved LCB 1

Various lightweight block cipher algorithms have been proposed to address the security requirements of Internet of Things (loT) devices, one of which is the Light Cipher Block (LCB). Initially proposed by Roy and colleagues in 2021, LCB underwent extensive evaluation against multiple cryptographic attacks. In 2023, Chan and colleagues identified a critical vulnerability in LCB's substitution box (S-box), which increased the cipher's linearity. To mitigate this issue, they improved LCB by integrating the S-box from the PRESENT cipher. This study conducts an algebraic analysis of LCB, identifying the algebraic characteristics underlying its vulnerabilities. In addition, an algebraic attack is performed on the improved LCB to evaluate its resilience against such attacks. Our findings reveal that while the original LCB remains susceptible to algebraic attacks, the improved version exhibits enhanced resistance. These results emphasize the importance of selecting appropriate S-boxes for cryptographic algorithms to strengthen their security against algebraic attacks. © 2024 IEEE.

Factoring large numbers poses a significant chal-lenge in contemporary cryptography and security practices. Shor's algorithm presents a remarkable advancement over clas- sical methods by providing exponential acceleration in factoring large numbers, presenting a possible risk to traditional cryptography methods. The algorithm relies on the Quantum Fourier Transform (QFT) and modular exponentiation principles to efficiently ascertain the period (x) of a given large number (N). Upon determining the period using classical methods, the prime factors of the large number can be easily computed. To eval- uate the algorithm's efficiency and scalability, both simulation- based experiments and theoretical analyses are conducted. The algorithm is simulated utilizing the Qiskit back end to estimate resources, including Clifford gates, T gates, T depth, Full depth, and qubits, across a range of large numbers. © 2024 IEEE.

The article considers the method of implementing Shannon's idea of building a cryptographically stable system by repeatedly applying relatively simple cryptographic transformations. At the same time was being solved the problem of simultaneously reducing the level of statistical vulnerabilities of the original sequence typical for block ciphers and fundamentally justified by the Kerckhoffs principle. It is suggested to reduce the sensitivity of existing cryptographic algorithms to existing cryptanalysis tools by implementing a universal solution suitable for any encryption algorithm. The main property of this solution is to increase crypto resistance by increasing the length of the key and the encrypted information block. The developed algorithms use the modification technique of symmetric block ciphers built on the architecture of the Feistel network. The proposed method is characterized by simplicity and transparency of solutions. An analysis of its main characteristics concerning classical algorithms built on the architecture of the Feistel network was carried out. It has been established that the time of multi-stage encryption decreases to the time of implementing a single round of encryption. Accordingly, the decryption time reduces to the execution time of two rounds - the encryption round and the decryption round. Therefore, high indicators of the cipher's two main properties - bandwidth and reliability - are provided. © 2024 IEEE.

Encrypted computation opens up promising avenues across a plethora of application domains, including machine learning, health-care, finance, and control. Arithmetic homomorphic encryption, in particular, is a natural fit for cloud-based computational services. However, computations are essentially limited to polynomial circuits, while comparisons, transcendental functions, and iterative algorithms are notoriously hard to realize. Against this background, the paper presents an encrypted system identification service enabled by a reliable encrypted solution to least squares problems. More precisely, we devise an iterative algorithm for matrix inversion and present reliable initializations as well as certificates for the achieved accuracy without compromising the privacy of provided I/O-data. The effectiveness of the approach is illustrated with three popular identification tasks. © 2024 IEEE.

Organizations all over the globe produce a lot of data every day because of the development of e-commerce apps, social networks, the World Wide Web, and other technologies. An intrusion occurs when hackers breach the data and use it to their benefit. Securing information is difficult in the internet era since terabytes of data are being generated daily and an online platform is available every second for user demands. Therefore, the current world’s information security depends heavily on cryptography algorithms, which make the online environment safer. In terms of using the cryptography algorithm, you can ensure confidentiality, authentication, integrity, availability, and identification for genuine users, as well as protect sensitive data and information from unauthorized persons. The cryptography methods (encryption and decryption) use mathematics to secure data, and there are various cryptography algorithms available, but appropriate algorithm selection is vital for secure communication that delivers heightened security, reliability, and performance to meet the requirements of a user. This survey paper aims to provide an overview of popularly used cryptography algorithms and show their significance when deploying security in the required environment. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.
