Conventional RSA algorithm, being a basis for several proposed cryptosystems, has remarkable security laps with respect to confidentiality and integrity over the internet which can be compromised by state-of-the-art attacks, especially, for different types of data generation, transmission, and analysis by IoT applications. This security threat hindrance is considered to be a hard problem to solve on classical computers. However, bringing quantum mechanics into account, the concept no longer holds true. So, this calls out for the modification of the conventional pre-quantum RSA algorithm into a secure post-quantum cryptographic-based RSA technique. In this research, we propose a post-quantum lattice-based RSA (LB-RSA) for IoT-based cloud applications to secure the shared data and information. The proposed work is validated by implementing it in 60-dimensions. The key size is about 1.152×105-bits and generation time is 0.8 hours. Furthermore, it has been tested with AVISPA, which confirms security in the presence of an intruder. Moreover, the proposed LB-RSA technique is compared with the existing state-of-the-art techniques. The empirical results advocate that the proposed lattice-based variant is not only safe but beats counterparts in terms of secured data sharing.

The latest quantum computers have the ability to solve incredibly complex classical cryptography equations particularly to decode the secret encrypted keys and making the network vulnerable to hacking. They can solve complex mathematical problems almost instantaneously compared to the billions of years of computation needed by traditional computing machines. Researchers advocate the development of novel strategies to include data encryption in the post-quantum era. Lattices have been widely used in cryptography, somewhat peculiarly, and these algorithms have been used in both; (a) cryptoanalysis by using lattice approximation to break cryptosystems; and (b) cryptography by using computationally hard lattice problems (non-deterministic polynomial time hardness) to construct stable cryptographic functions. Most of the dominant features of lattice-based cryptography (LBC), which holds it ahead in the post-quantum league, include resistance to quantum attack vectors, high concurrent performance, parallelism, security under worst-case intractability assumptions, and solutions to long-standing open problems in cryptography. While these methods offer possible security for classical cryptosytems in theory and experimentation, their implementation in energy-restricted Internet-of-Things (IoT) devices requires careful study of regular lattice-based implantation and its simplification in lightweight lattice-based cryptography (LW-LBC). This streamlined post-quantum algorithm is ideal for levelled IoT device security. The key aim of this survey was to provide the scientific community with comprehensive information on elementary mathematical facts, as well as to address real-time implementation, hardware architecture, open problems, attack vectors, and the significance for the IoT networks.
With the fast-paced development of quantum computing, classical cryptographic techniques are under severe security threats, prompting the need for post-quantum cryptographic mechanisms for secure data exchange in next-generation network communications. Post-quantum cryptography seeks to protect sensitive data against quantum attacks to provide long-term data confidentiality. But all current cryptographic techniques, including RSA and ECC, are susceptible to quantum algorithms like Shor's algorithm, which can factor large integers efficiently and break discrete logarithm problems, making classical cryptography useless. There is thus a pressing need for quantum attack-resistant encryption mechanisms. To meet these challenges, we introduce the Lattice-Based Cryptography with Hybrid Key Exchange (L-CHKE) framework, which combines lattice-based encryption with a hybrid key exchange mechanism. Lattice-based cryptography provides quantum resistance because it is based on hard mathematical problems such as Learning with Errors (LWE), which provides greater security and efficiency. The designed L-CHKE algorithm strengthens secure key distribution and authentication for next-generation networks, especially for applications needing strong security like financial transactions, IoT, and military communications. Experimental results verify that L-CHKE noticeably boosts computational efficiency by 98.45%, decreases key exchange latency by 42.56%, and guarantees robustness by 97.64% against quantum attacks, indicating it is an appropriate solution for post-quantum secure communication.
The rise of quantum computing poses a serious threat to traditional cryptosystems, such as RSA and ECC, which rely on the mathematical problem of factoring large numbers and dealing with discrete logarithms Quantum algorithms such as Shor and Grover can solve solve these problems effectively, so that classical The encryption is simple. This research addresses the urgent need for quantum-resistant cryptographic algorithms to protect next-generation networks, including 5G, IoT, and cloud computing, from future quantum attacks. The main objective of this study is to investigate the efficiency and scalability of quantum post-cryptography techniques, especially lattice-based cryptography, and to evaluate their performance in comparison with traditional cryptography and other post-quantum techniques. It also provides robust protection against quantum attacks and reasonable scalability to large networks, while delivering large key size requirements, low connectivity and excess capacity. The study concludes that lattice-based cryptography is an appropriate solution that balances quantum resistance with practical performance in real-world applications to ensure secure communications in the post-quantum era.
A lightweight, robust, and efficient security mechanism is necessary to combat quantum-generation threats across multiple domains, including healthcare, transportation, and industrial automation, in the Internet of Things (IoT). Post-quantum cryptography has emerged in response to the increasing vulnerability of traditional cryptographic methods, such as RSA and ECC, to quantum attacks. Taking advantage of the hardness of Short Integer Solutions (SIS) and Learning with Errors (LWE), we propose a lattice-based signature scheme for IoT applications. A computationally efficient IoT device model that maintains authenticated, integrity, and anonymity is proposed. The scheme has the advantage of being faster and more efficient than existing key size schemes such as IBS, CLS, and FALCON, according to a detailed security assessment. The proposed scheme maintains practical deployment ability while reducing post-quantum security in IoT ecosystems.
