Amid breakthroughs in quantum computing, blockchain systems are experiencing a dual-track evolution characterized by threats from quantum attacks and empowerment through quantum technologies. Traditional blockchain architectures, which rely on public-private key cryptography and hash functions, face systemic risks to core functions such as transaction integrity verification and consensus security when exposed to quantum attacks. This paper systematically analyzes and compares two distinct technical approaches in the field of quantum-secure blockchain: post-quantum blockchain and quantum blockchain. The former enhances existing systems by integrating post-quantum cryptographic algorithms to resist quantum threats, aiming for a smooth transition from current architectures. The latter reconstructs distributed ledger technology based on quantum information properties such as entanglement, forming novel architectures involving quantum key distribution networks, quantum digital signatures, and quantum consensus algorithms. The feasibility and development potential of these approaches are examined in application scenarios such as industrial IoT. A comparative analysis is conducted on their technical constraints and implementation challenges from the perspectives of transaction efficiency, security model validation, and standardization maturity. This lays a foundation for future empirical research. Finally, potential development paths are discussed, and targeted research directions such as diversified migration and dynamic hybrid strategies are proposed to guide further studies.
Quantum computing has the potential to transforming computational paradigms, posing both a threat and an opportunity to contemporary cryptographic systems and data security frameworks. As quantum algorithms improve, pose a risk to traditional encryption solutions, and the concepts of post-quantum cryptography and quantum-safe security architectures gain momentum, it is of paramount importance that organizations stay ahead of the threat landscape. Keywords— Quantum Computing, Cryptography, Information Systems. This work reviewed the implications of quantum computing in the field of Cryptography and Data Security within Information Systems, analyzing three relevant problems encountered: secure key distribution, computational performance and cryptographic migration; Many works were unable to empirically validate or implement quantum-resistant algorithms in the real world, which represents a significant limitation to existing studies. This work tries to fill this gap by characterizing the security of post-quantum cryptography, including lattice-based, hash-based, and multivariate polynomial cryptosystems, from quantum attacks. Furthermore, we provide a multi-layered security framework that combines quantum-safe encryption, AI-powered anomaly detection, and blockchain-based authentication that would increase resilience against quantum attacks. This research bridges the gap by offering sector-specific insights into quantum security needs across key industries, including finance, healthcare, and government, facilitating the drafting of a standardized security framework and policy recommendations for a quantum-secure future. The research will help organizations and policymakers understand how they can implement scalable quantum-resistant cryptographic solutions and address potential cybersecurity risks associated with the post-quantum world.

This article explores the profound impact of quantum computing on cybersecurity, highlighting the potential threats to current cryptographic systems and the emerging solutions in the field of quantum-safe security. It begins by explaining the fundamental principles of quantum computing, contrasting them with classical computing, and detailing how quantum algorithms like Shor's and Grover's pose significant risks to widely used encryption methods such as RSA and AES. The article then delves into the development of post-quantum cryptography, discussing various approaches including lattice-based, code-based, and multivariate polynomial cryptography, with a focus on the NIST standardization initiative. Additionally, it examines quantum cryptography techniques, particularly Quantum Key Distribution (QKD), as alternative methods for secure communication. The article concludes by addressing the challenges organizations face in transitioning to quantum-safe security, including expertise gaps, resource limitations, and financial implications. It emphasizes the urgency of preparing for the quantum era while acknowledging the complexities involved in implementing quantum-resistant measures across global networks. This comprehensive overview provides insights into the evolving landscape of cybersecurity in the face of advancing quantum technologies and underscores the critical need for proactive strategies to safeguard digital infrastructure in the coming quantum age.
The emergence of quantum computing presents unprecedented challenges to contemporary enterprise cybersecurity frameworks. Current cryptographic systems that protect sensitive data and secure communications will become vulnerable to quantum attacks within the next decade. This research examines the implications of quantum computing advancement for enterprise and cloud information systems, proposing quantum-resilient architectural frameworks that can withstand both classical and quantum threats. We analyze the timeline of quantum computing development, assess vulnerabilities in existing enterprise security infrastructures, and evaluate post-quantum cryptographic approaches suitable for organizational implementation. Through comparative analysis of quantum-resistant algorithms and architectural patterns, this study demonstrates that enterprises must begin transitioning to quantum-safe systems immediately despite quantum computers' current limitations. The research reveals that organizations storing long-lived sensitive data face immediate risks from "harvest now, decrypt later" attacks where adversaries collect encrypted data today for future quantum decryption. Our proposed architecture integrates post-quantum cryptography, hybrid classical-quantum security approaches, and crypto-agility frameworks that enable organizations to adapt as quantum threats evolve. The findings contribute practical guidance for enterprise architects, security professionals, and cloud service providers navigating the transition to quantum-resilient information systems. This work emphasizes that quantum preparedness is not a future concern but an urgent present requirement for organizations handling sensitive data with long confidentiality requirements.
As an important strategic resource for safeguarding national information security and the healthy development of digital economy, cryptography is the cornerstone of protecting the security of critical infrastructure, government affairs data, financial transactions, and other fields. Currently, the rapid development of quantum computing poses a disruptive challenge to the existing public-key cryptosystems and a fatal threat to the global information security landscape, making research on post-quantum public-key cryptography (PQC) both necessary and urgent. This study expounds on the current development status of five mainstream technical routes in PQC: lattice-based, code-based, hash-based signature, multivariate, and isogeny-based cryptography, and finds that each of these five routes has its own focus yet is in a stage of continuous iteration and verification. The study identifies the existing issues of the development of PQC including performance bottlenecks, insufficient ecological compatibility, and difficulties in security evaluation. Meanwhile, the development of PQC in China is confronted with challenges such as a weak foundation in theoretical research, lagging standards formulation, an imperfect industrial ecosystem, and a shortage of professional talents. To safeguard China's information security in the quantum computing era, we propose the following suggestions: strengthening basic research to enhance the independent innovation capability of the industry; accelerating standards formulation to boost international discourse power; improving the industrial ecosystem to promote the phased migration to PQC; intensifying talent cultivation to build a professional talent team. These measures are expected to help China construct a multi-dimensional and highly resilient digital security ecosystem, and drive the leap-forward development of China's cyberspace security capability from classical to quantum security.
