The lightning pace of the progress in quantum computing has far-reaching ramifications in cryptography and most common cryptographic operations, guaranteeing confidentiality, verifiability, integrity, are susceptible. Shor breaks such protocols in polynomial time. Like in the case of the public key systems, symmetric systems fall under the attack of a Grover algorithm that halves its practical key size. This paper views two sides of the two-fold impact of quantum computers on cryptography: they are disruptive to the classical cryptosystems, and could be enabling to the quantum-resistant ones. Prefix-new post-quantum cryptosystems, which include the lattice-based, hash-based, and multivariate Although security achieved using quantum based technologies is conceptually un-hackable, various practical concerns are still to be met including how its mass production can be scaled, cost/infrastructure. The review highlights on the imminent necessity of the future-leaning study, standardization, and global collaboration to maintain digital communication within the quantum era, ensuring a safe transition between the classical and the post-quantum cryptosystems.

While advances in quantum computing promise new opportunities for scientific advancement (e.g., material science and machine learning), many people are not aware that they also threaten the widely deployed cryptographic algorithms that are the foundation of today's digital security and privacy. From mobile communications to online banking to personal data privacy, literally billions of Internet users rely on cryptography every day to ensure that private communications and data stay private. Indeed, the emergence and growth of the public Internet and electronic commerce was arguably enabled by the invention of public-key cryptography. The key advantage offered by public-key cryptography is that it allows two parties who have never communicated previously to nevertheless establish a secure, private, communication channel over a non-private network (e.g., the Internet). Recent advances in quantum computing signal that we are on the cusp of our next cryptographic algorithm transition, and this transition to post-quantum cryptography will be more complicated and impact many more systems and stakeholders, than any of the prior migrations. This transition represents a major disruption within the IT industry and will broadly impact nearly every domain of our digital lives, from global commerce to social media to government and more. Cryptographic algorithm transitions take time and involve an extensive coordination effort across many stakeholders who are involved in building and operating the world's compute infrastructure. By preparing now for the upcoming transition to these new algorithms, we can ensure a more orderly, less costly, and minimally disruptive changeover.

Event:Symposium "Comprehensive Transport Security," FGBOU VO SPbSU GA named after A.A. Novikov Introduction: New Challenges for Information Security In September 2022, the World Economic Forum (WEF), in collaboration with Deloitte, published a technical report outlining a roadmap for organizations aiming to achieve a quantum-safe economy. The document emphasizes how entities can maximize opportunities while minimizing risks associated with the advent of quantum computing. The 35-page report provides guidance for a secure transition toward quantum-safe systems. Its recommendations are based on discussions among senior members of the WEF Quantum Security Working Group, a specialized network within the broader global quantum computing initiative. Three-Stage Approach for a Secure Transition Increase Awareness of the Quantum ThreatOrganizations must understand the potential risks posed by quantum computing to existing cryptographic systems, particularly public-key encryption, which is vulnerable to algorithms like Shor’s algorithm. Develop a Quantum Security Strategy and Transition RoadmapA clear strategy should define short-, medium-, and long-term steps for implementing quantum-resistant cryptography and protecting critical data assets. Start the Transition Early with Hybrid SolutionsEarly adoption of hybrid cryptographic systems—combining classical and quantum-safe algorithms—enables a gradual and controlled transition to fully quantum-resistant security infrastructures. Why Prioritize Economic Quantum Security? Proactive Risk Mitigation: Delaying action exposes organizations to future breaches, as sensitive information encrypted today may be decrypted by quantum computers tomorrow. Competitive Advantage: Early adopters of quantum-safe solutions can secure trust, reputation, and operational continuity in the digital economy. Strategic Planning: Organizations can integrate quantum resilience into their IT infrastructure without disruptive overhauls.
