This work considered the improvement of the RSA cryptosystem using a Secure Hash Algorithm, SHA-256, in its attempt to forestall attacks, more so against timing attacks. RSA is one of the most used asymmetric encryption methods, and with computational power ever increasing these days and new complex methods of attack ever emerging, this method is under severe threat. It also pointed out some intrinsic weaknesses in RSA, including vulnerability to side-channel attacks and deterministic encryption that could result in key exposure via timing variations. In this work, SHA-256 is used because it is a very sound hashing algorithm that can enhance the randomness of the produced ciphertext against cryptographic attacks. This improvement is thus proposed to reduce the execution time of RSA operations, which can hide timing information that could be used in attacks. Efficiency with respect to such an integration is studied through controlled experiments that assess timing behaviors and search for vulnerabilities. The results show that this combined approach, while actually reinforcing the security in RSA against timing attacks, has an even broader implication with regard to the importance of implementation details in cryptographic algorithms. The research contributes towards the constant dialogue in improving data security within cryptographic systems, putting forward a framework by which future studies can better resilient encryption methodologies. © 2024 IEEE.

In this paper, we discuss the challenges of quantum computing to traditional cryptography and the latest development of post-quantum cryptography as a coping strategy. As quantum computing advances, cryptographic algorithms that rely on the complexity of classical computers, such as RSA and ECC, are at risk of failing, which has prompted the cryptography community to seek new encryption solutions. Post-quantum cryptography focuses on encryption technology and develops resistance to quantum computing attacks. It studies encryption schemes based on lattice theory, multivariate polynomials, coding theory, and hash functions. In addition, lattice-based cryptography is critical. It builds multiple algorithms, including RLWE and NTRU, focusing on LWE and SIS issues, demonstrating strong potential in a quantum computing environment. In terms of signature algorithms, Dilithium and Falcon lattice-based schemes are the focus of standardization. In the simulation analysis of these algorithms, we evaluated their security, efficiency, and compatibility, laying the theoretical and practical foundation for the cryptosystem transformation in the post-quantum era. © 2024 IEEE.

The rapid advancements in quantum computation pose significant threats to traditional cryptographic systems, such as those used in the Internet of Things (IoT). RSA and methods like Elliptic Curve Cryptography (ECC) are particularly vulnerable to quantum algorithmic techniques, such as Shor's and Grover's algorithms. This paper focuses on the analysis of cryptographic models based on quantum technologies, with special emphasis on IoT security. It examines how both symmetric and public-key cryptography are affected by quantum comput-ing - highlighting vulnerabilities in symmetric schemes to Grover's algorithm and in public-key systems like ECC to Shor's algorithm. Significant focus is placed on the advancement of quantum-resistant ECC, with an in-depth evaluation of its effectiveness, security capabilities, and suitability for IoT applications. This work also compares various methods for implementing quantum-enhanced ECC, considering both software and hardware solutions. Furthermore, the paper explores emerging hybrid systems that integrate classical and quantum-resistant encryption to offer enhanced security in transitional scenarios. Lastly, it outlines potential research avenues for developing new techniques to protect future IoT networks from quantum-based attacks. © 2024 IEEE.

A Python optimization method is proposed to ad-dress the slow and inefficient encryption speed of third-party libraries (gmssl and pysmx) commonly used in Python to im-plement national security encryption algorithms. This method combines bit operations, memory construction of S-boxes, and other methods to improve the encryption speed of national secu-rity algorithms. Through laboratory comparison and verification, compared to existing third-party national security encryption algorithm libraries, this method can effectively improve the speed of implementing national security encryption algorithms in Python. © 2024 IEEE.

11th International Scientific Conference "Information Technology and Implementation", IT and I 2024

The development of a digital signature algorithm based on elliptic curves, which is based on the basic models of asymmetric cryptography, confirms the increased security of the authentication procedure, which in turn is the primary task of ensuring the correct functioning of the system and the introduction of updated software solutions, the construction of which is the result of a detailed analysis of state standardisation. When determining the mathematical nature of elliptic curves, it can be established that they are complex algebraic objects that create obstacles to hacking due to the impossibility of solving the discrete logarithm problem to find a base point when the order of the elliptic curve is large. Consideration of the mathematical structure of elliptic curves and their practical use in software solutions based on the modernisation and optimisation of the use of the DSTU 4145-2002 standard is of great theoretical and practical importance, which is to create an opportunity for further evaluation of the effectiveness of cryptographic methods and improvement of the random sequence generator using both physical and functional sources, which is more productive and efficient in the context of setting the initial state of random sequences. © 2024 Copyright for this paper by its authors.

The main aim of the paper is to evaluate and compare the hardware implementation of three lightweight cryptographic algorithms - SKINNY, ForkAE, and Romulus to determine their efficiency and suitability for IoT environments. Methods used: theoretical analysis and summary. The study indicates that SKINNY shows good results in round-based implementations but is less efficient in serial modes, while ForkAE offers better performance for small message encryption with minimal latency. Romulus is noted for its compact hardware footprint and efficient serial mode operation, making it suitable for low-power applications. These findings underscore the importance of selecting appropriate cryptographic solutions to balance security, performance, and resource constraints in IoT systems. © 2024 IEEE.

The security of IoT applications remains one of the biggest challenges, given that the vast majority of applications are developed on devices with limited computational resources and interconnected by the Internet. By 2027, the number of active IoT applications is expected to reach approximately 30 billion, with a massive amount of data being transmitted over the Internet. Therefore, this information must be protected, as a vulnerable IoT application can lead to serious issues such as data leaks and manipulations. Thus, classical cryptographic algorithms become highly costly or even unfeasible. Optimized AES algorithms are found in the literature to provide lightweight cryptography, but none evaluate energy consumption. Faced with the challenge of implementing secure IoT applications while consuming the least energy possible, this work extends the evaluation of our previously proposed lightweight AES, assessing the energy consumption of the optimizations made in both the SubBytes and MixColumns stages. With the implemented optimizations, it was possible to achieve a reduction in energy consumption of 63.87% and 70.86% on the ESP32 and Raspberry Pi Pico platforms, respectively, when compared to the original version of the AES algorithm, making this version more viable for protecting IoT applications. © 2024 IEEE.

As the advent of quantum computing looms, the cryptographic landscape faces unprecedented challenges that could render traditional algorithms like AES, RSA, and ECC vulnerable. This paper delves into a comparative study of these classical cryptographic algorithms, examining their foundational principles and evaluating their resilience against quantum computing threats, particularly Shor's and Grover's algorithms. Through a combination of theoretical analysis and practical simulations, we assess the potential weaknesses and strengths of AES, RSA, and ECC in the post-quantum era. The study highlights the need for quantum-resistant cryptographic methods and explores how current algorithms can be adapted or replaced to withstand the sophisticated computational capabilities of quantum computers. By bridging the gap between classical and quantum cryptography, this research offers crucial insights into the future of secure digital communication, underscoring the urgency for innovation in cryptographic practices to safeguard data in an increasingly quantum-dominated world. © 2024 IEEE.
