The rapid development of quantum computing poses a direct threat to RSA, DSA, and ECC modern cryptographic systems due to the Shor's algorithm potential application. In response to this threat, the NIST is conducting post-quantum cryptography standardization, having selected lattice-based and hash-function-based algorithms in 2022. Cryptosystems based on noncommutative groups, despite their potential resistance to quantum attacks owing to natural properties of noncommutative algebraic structures, were not included in the first set of standards due to the complexity of security analysis. This research conducts a comprehensive analysis of the cryptographic competitiveness of noncommutative group-based systems, evaluates their advantages and disadvantages compared to existing post-quantum solutions, and determines prospects for practical application as an alternative or complementary solution to ensure cryptographic diversification under quantum threats.

The advent of quantum computing poses a significant threat to current cryptographic systems, particularly public-key algorithms such as RSA and ECC, which are vulnerable to quantum attacks like Shor's algorithm. Post-Quantum Cryptography (PQC) aims to develop and standardize quantum-resistant cryptographic algorithms to secure digital communications in the quantum era. This paper examines the current landscape of PQC, focusing on the evaluation and standardization efforts led by organizations such as the National Institute of Standards and Technology (NIST). We analyze the major families of quantum-resistant algorithms, including lattice-based, hash-based, code-based, multivariate, and isogeny-based cryptography, discussing their security guarantees, performance trade-offs, and implementation challenges. Furthermore, we review NIST's PQC standardization process, highlighting selected finalists and alternate candidates, and explore the ongoing transition challenges in adopting these algorithms across industries. Finally, we discuss future directions for PQC research, including hybrid cryptographic systems and the need for continued cryptanalysis to ensure long-term security. This work provides a comprehensive overview of the progress and challenges in deploying quantum-resistant cryptography to safeguard against emerging quantum threats.
The development of quantum computing poses a very real threat to traditional cryptography, especially these, which are number-theoretic like RSA and ECC. With the more and more development of quantum algorithms such as Shor and Grover, there is an immediate necessity to come up with cryptographic protocols that are resistant to quantum attacks. This paper reviews and discusses different quantum-resistant (post-quantum) cryptographic schemes, such as lattice-based, code-based, multivariate, hash-based, and isogeny-based cryptography. It compares these protocols on the assumptions of their security and their efficiency in their computation and the size of their keys as well as their possible integrations into the existing communication infrastructure. Moreover, we also evaluate the standardization process by NIST and the difficulties of moving towards post-quantum security in practical use. This paper proposes a scalable comparison system, which correlates the hypothetical security basis of postquantum cryptography with the ability to effectively operate in the real world. It has emphasized protocol interoperability, migration compatibility and trade-offs in performance that gives a viable roadmap towards quantum-resistant cryptographic protocols implementation into current communication infrastructures whilst also providing scalable and future secure communication systems. This study, by emphasizing the potential and the drawbacks of the existing post-quantum cryptography schemes, helps in a more precise idea of the directions to follow on the way to a secure, future-proof communications scheme.
The emergence of quantum computing poses a serious threat to traditional communication systems, endangering the security of digital communications and critical infrastructure. Although existing cryptographic algorithms (such as RSA and ECC) rely on the inefficiency of computing large numbers or solving logarithm inequality problems, quantum algorithms (especially Shor's algorithm) can solve these problems efficiently. To mitigate this threat, the field of post-quantum cryptography (PQC) has emerged and focuses on developing cryptographic systems that are resilient to quantum attacks. The main techniques in PQC include lattice-based, hash-based, code-based, and multivariate polynomial cryptography. Lattice-based cryptography is the leading contender, providing high security and supporting good properties such as fully homomorphic encryption, but facing issues related to size and computational efficiency. Hash-based encryption enables strong digital signatures but has limitations. Code-based encryption based on error-correcting codes provides proof of security but requires small size. Multivariate polynomial cryptography has good performance but has drawbacks in some applications. While standardization efforts led by organizations such as NIST continue, PQC is at the forefront of protecting the digital future from the impact of quantum computing, ensuring the integrity and confidentiality of information in the post-quantum era.
The advent of quantum computing will pose a substantial threat to the security of classical cryptographic methods, which could become vulnerable to quantum-based attacks. In response to this impending challenge, the field of post-quantum cryptography has emerged, aiming to develop algorithms that can withstand the computational power of quantum computers. This study addressed the pressing concern of classical cryptographic methods becoming vulnerable to quantum-based attacks due to the rise of quantum computing. The emergence of post-quantum cryptography has led to the development of new resistant algorithms. Our research focused on four quantum-resistant algorithms endorsed by America’s National Institute of Standards and Technology (NIST) in 2022: CRYSTALS-Kyber, CRYSTALS-Dilithium, FALCON, and SPHINCS+. This study evaluated the security, performance, and comparative attributes of the four algorithms, considering factors such as key size, encryption/decryption speed, and complexity. Comparative analyses against each other and existing quantum-resistant algorithms provided insights into the strengths and weaknesses of each program. This research explored potential applications and future directions in the realm of quantum-resistant cryptography. Our findings concluded that the NIST algorithms were substantially more effective and efficient compared to classical cryptographic algorithms. Ultimately, this work underscored the need to adapt cryptographic techniques in the face of advancing quantum computing capabilities, offering valuable insights for researchers and practitioners in the field. Implementing NIST-endorsed quantum-resistant algorithms substantially reduced the vulnerability of cryptographic systems to quantum-based attacks compared to classical cryptographic methods.
