Quantum-Safe Technology for Entrepreneurs

Happy to see my article has been published at ABP Live on "Beyond AI: Why Quantum-Safe #Cryptography Is a Business Imperative in 2025" The alarming rise in cyberattacks—both in India and globally—makes one thing painfully clear: traditional encryption is no longer enough. In India alone, businesses stand to lose ₹20,000 crore this year, while global cybercrime costs are projected to reach $13.82 trillion by 2028. Even worse? The impending quantum era threatens to render our current cryptographic systems obsolete. Technologies like RSA, which power everything from internal communications to critical external collaborations, are vulnerable to quantum-enabled decryption. So what must businesses do right now? Embrace Quantum-Safe Messaging: Opt for end-to-end encrypted platforms designed to withstand quantum attacks, especially for communications with clients, partners, and vendors. Follow Standards and Best Practices: NIST has already rolled out the first wave of Post-Quantum Cryptography (PQC) standards—like ML-KEM for encryption and ML-DSA for digital signatures. Think Strategically, Not Just Tactically: Transitioning to PQC is more than a technical upgrade—it’s a strategic initiative. Build governance, crypto-agility, and roadmap planning into your cybersecurity strategy. What the world is doing: - Europe aims to migrate to quantum-safe encryption by 2030, starting with risk assessments and awareness campaigns in 2026 - The UK’s NCSC is urging organizations to begin full migration planning by 2028 and complete it by 2035 - Setting an example in the private sector, it has integrated post-quantum encryption into its WireGuard and Lightway protocols using NIST’s ML-KEM algorithm Reports from India’s BFSI sector show a worrying lack of readiness—yet almost 58% of CISOs recognize the threat within the next three years Key takeaway: Quantum-safe cryptography isn’t a futuristic concept—it’s a present-day necessity. The threat of "store now, decrypt later" attacks means the data we transmit today may be vulnerable tomorrow. Waiting isn’t an option Whether you’re in BFSI, government, telecoms, or healthcare, the time to act is now. Let’s lead the shift toward a secure quantum future. #QuantumSafe #Cybersecurity #PostQuantumCryptography #CryptoAgility #DigitalTrust #QuantumReady #QNulabs QNu Labs

The Quantum Cybersecurity Revolution: A Major Startup Opportunity in 2025 As quantum computing moves from theory to real-world applications, its impact on cybersecurity is becoming increasingly clear.

Quantum-Resistant Cryptography on the Rise • NIST Standards: The National Institute of Standards and Technology (NIST) has shortlisted algorithms for post-quantum cryptography (PQC) to prepare for quantum threats. • Hybrid Encryption Models: Solutions combining classical cryptography with post-quantum algorithms are emerging as a practical stopgap. • AI Integration: Artificial Intelligence is being paired with PQC to detect vulnerabilities and optimize encryption protocols. 4. Startup Opportunities in Quantum Cybersecurity • Quantum Key Distribution (QKD): Creating secure communication channels resistant to eavesdropping using quantum entanglement. • PQC Software Development: Startups are developing libraries for quantum-resistant algorithms. • Quantum-Safe Infrastructure: Designing networks capable of withstanding quantum decryption attempts. • Cloud Security: Quantum-secure cloud solutions are in demand, particularly among enterprises and governments. Startups positioned in these areas are expected to see increased venture capital interest and government contracts. 5. Challenges to Adoption • Awareness Gaps: Many organizations remain unaware of the quantum threat, slowing adoption of PQC solutions. • Cost of Transition: Upgrading legacy systems is resource-intensive and technically complex. • Regulatory Uncertainty: Standards for quantum-safe encryption are still evolving globally.

Quantum computing is advancing rapidly, bringing unprecedented processing power that threatens traditional encryption methods. The "collect now, decrypt later" strategy underscores the urgency of preparation, adversaries are already harvesting encrypted data with the intent to decrypt it once large-scale quantum computers become viable. Fortinet is leading the way in quantum-safe security, integrating NIST PQC algorithms, including CRYSTALS-KYBER, into FortiOS to safeguard data from future quantum-based attacks. "A recent real-world demonstration by JPMorgan Chase (JPMC) showcased quantum-safe high-speed 100 Gbps site-to-site IPsec tunnels secured using QKD. The test was conducted between two JPMC data centers in Singapore, covering over 46 km of telecom fiber, and achieved 45 days of continuous operation." "The network leveraged QKD vendor ID Quantique for the quantum key exchange, Fortinet’s FortiGate 4201F for network encryption, and FortiTester for performance measurement." This is not just a theoretical concern, organizations are already deploying quantum-safe encryption solutions. As quantum computing capabilities advance, organizations must adopt quantum-resistant security architectures and take proactive steps now to safeguard their sensitive information against future quantum-enabled attacks. These proactive methods include: -adopting hybrid cryptographic approaches, combining classical and PQC algorithms, ensuring interoperability and a phased transition -implementing crypto-agile architectures, for seamless updates to encryption mechanisms as new quantum-resistant standards emerge -leveraging PQC capable HSMs and TPMs -evaluating network security architectures, such as ZTNA models -ensuring authentication and access controls are resistant to quantum threats. -identifying mission-critical and long-lived data, that must remain secure for decades. -implementing sensitivity-based classification, determine which datasets require the highest level of post-quantum protection. -conducting risk assessments to evaluate data exposure, storage locations, and current encryption standards. -transitioning to quantum-resistant encryption algorithms recommended by NIST’s PQC standardization efforts. -establishing data-at-rest and data-in-transit encryption policies, mandate use of PQC algorithms as they become available. -strengthening key management practices -developing GRC frameworks ensuring adherence to post-quantum security. -implementing continuous cryptographic monitoring to detect and phase out vulnerable encryption methods. -enforcing regulatory compliance by aligning with emerging PQC standards. -establishing incident response plans to handle quantum-driven cryptographic threats proactively. Fortinet remains committed to pioneering quantum-safe encryption solutions, enabling organizations to stay ahead of emerging cryptographic threats. Read more from Dr. Carl Windsor, Fortinet’s CISO!

IS YOUR ENTERPRISE READY FOR "Q-DAY"? "Q-day" (or Quantum Day) is the point in time when quantum computers become powerful enough to break the public-key encryption (like RSA or ECC) that currently secures global digital, financial, and government infrastructure. Our current best estimates is that Q-Day will happen by 2029! Huge thanks to Dr. Rob Campbell, FBBA. , IBM Global Quantum-Safe Executive and IBM Quantum Ambassador, for guest lecturing to our University of Arkansas ­- Sam M. Walton College of Business EMBA students. His insights into the "Quantum-Safe" transition provided a crucial roadmap for how leadership must navigate the next few years of cybersecurity. Here's what we learned: Adversaries are currently collecting encrypted data to store and decrypt once quantum computers are powerful enough to calculate private keys—a strategy known as "Harvest now, decrypt Later". Because enterprise cryptographic migrations can take 5 to 15+ years, many large organizations will still be in transition when quantum computers become capable of breaking current encryption. What enterprises can do NOW: Dr. Campbell emphasized that Post-Quantum Cryptography (PQC) is a leadership issue, not just a technical one. To preserve trust and resilience, leaders should authorize these "low-regret" actions immediately: - Inventory cryptographic dependencies: identify what you have before you plan what to change. - Prioritize high-value data: Focus on data with the longest confidentiality horizons, not just the most "critical" systems. - Invest in crypto-agility: Design systems for the permanent ability to swap algorithms without rebuilding the entire architecture. - Pilot PQC today in non-mission critical systems: PQC standards were finalized by NIST in 2024 and are ready for deployment on classical computers now. Enterprises can learn in these lower risk systems. - Communicate metrics to boards in non-technical jargon. Dr. Campbell noted, the question is whether we manage this change deliberately now or inherit it under pressure later. He stressed the importance of wide-spread education. To that end, Professor Daniel Conway will be offering the Walton College's first Quantum Computing class this fall! Adam Stoverink, Ph.D.; Shaila Miranda; Brian Fugate; Brent D.

EY’s perspective on securing against #quantum #risks emphasizes that quantum #computing is rapidly evolving from a theoretical concern into a material cybersecurity threat that requires immediate strategic action. The core issue lies in the vulnerability of widely used cryptographic algorithms, such as RSA and elliptic curve cryptography, which could be broken by sufficiently advanced quantum computers. This creates a systemic risk to sensitive data, including financial information, intellectual property, and personal records. A central concept highlighted is the “harvest now, decrypt later” threat model, in which adversaries collect encrypted data today with the intention of decrypting it in the future as quantum capabilities mature. This makes quantum risk a present-day problem, particularly for data requiring long-term confidentiality. EY stresses that organizations must adopt a proactive and structured approach to quantum readiness. A foundational step is to conduct a comprehensive cryptographic inventory, identify sensitive #data, and map existing #encryption methods. This enables organizations to assess which systems are most exposed and prioritize remediation efforts. Transitioning to post-quantum cryptography (PQC) is a complex, multi-year transformation that requires careful planning, integration into existing #technology roadmaps, and alignment with emerging standards. Organizations are encouraged to build crypto-agility, allowing them to adapt encryption methods as technologies and standards evolve. EY also highlights the importance of #governance, #compliance, and #workforce readiness. Quantum resilience requires enterprise-wide coordination, including policy development, regulatory alignment, continuous monitoring, and personnel training. EY frames quantum cybersecurity not just as a technical upgrade but as a strategic #transformation initiative. Organizations that act early can strengthen resilience, improve cyber maturity, and gain a competitive advantage, while those that delay risk long-term exposure to data breaches, regulatory challenges, and erosion of #digital #trust.
