Quantum-Safe Migration Strategies for IT Teams

NIST – Migration to Post-Quantum Cryptography Quantum Readiness outlines a comprehensive framework for transitioning cryptographic systems to post-quantum cryptography (PQC) in response to the emerging threat of quantum computers. Quantum technology is advancing rapidly and poses a significant risk to current public-key cryptographic methods like RSA, ECC, and DSA. This guide aims to assist organizations in preparing for and implementing PQC to safeguard sensitive data and critical systems. Key Points  The Quantum Threat Quantum computers are expected to disrupt cryptography by efficiently solving mathematical problems that underpin widely used encryption and key exchange methods. This would render current public-key systems ineffective in protecting sensitive data, emphasizing the need for cryptographic agility.  NIST PQC Standards NIST is spearheading efforts to standardize quantum-resistant algorithms through an open competition and evaluation process. These algorithms, designed to withstand quantum attacks, focus on two primary areas: 1. Key Establishment: Protecting methods like Diffie-Hellman and RSA key exchange. 2. Digital Signatures: Securing authentication processes.  Migration Framework The document provides a phased approach to migrating cryptographic systems to PQC: 1. Assessment Phase:    - Inventory cryptographic dependencies in current systems.    - Evaluate systems at risk from quantum threats based on sensitivity and lifespan. 2. Preparation Phase:    - Conduct pilot testing of candidate PQC algorithms in existing infrastructure.    - Develop a hybrid approach that combines classical and post-quantum algorithms to ensure interoperability during transition. 3. Implementation Phase:    - Replace vulnerable cryptographic methods with PQC in a phased manner.    - Ensure scalability, performance, and compatibility with existing systems. 4. Monitoring and Updates:    - Continuously monitor the effectiveness of implemented solutions.  Challenges in PQC Migration - Performance Impact: PQC algorithms often have larger key sizes, increased latency, and greater computational demands compared to classical algorithms. - Interoperability: Ensuring smooth integration with legacy systems poses significant technical challenges.  Best Practices - Use hybrid encryption to maintain compatibility while testing PQC algorithms. - Engage in collaboration with vendors, industry groups, and government initiatives to align with best practices and standards. Conclusion The transition to post-quantum cryptography is a proactive measure to secure data and communications against future threats. NIST emphasizes the importance of starting preparations immediately to mitigate risks and ensure a smooth, efficient migration process. Organizations should focus on inventorying dependencies, piloting PQC solutions, and developing cryptographic agility to adapt to this transformative technological shift.

💡 Meta publishes their approach to transition to #PQC Meta publishes a detailed article showing how they approach the transition to PQC in a move that shows commitment to continuously raise its security bar to deploy the most advanced security and cryptographic protection techniques, and to lead by example. First actions taken include: 👉 Creating a workgroup to migrate to PQC, spanning from internal infrastructure to user-facing apps. 👉 Recognizing that this is a highly complex multi-year effort. 👉 Executing a priority analysis. Their first target has been securing the confidentiality in internal TLS traffic. They took this decision because: ☝ they control both endpoints and manage their own TLS library, so they have no external dependencies, ✌ they regard internal TLS as a highly sensible use case, so it is a top priority. Their choice for key exchange is Kyber + ECC X25519 in hybrid mode. They use Kyber768 as default and Kyber512 in some use cases where they need low latency. They explain different issues found in the process, like bugs in the liboqs library, increased latency with Kyber768 due to the size of the public key exceeding the maximum network packet size or when resuming TCP Fast Open (TFO). They also confirm that Kyber768 seems to require less CPU cycles than X25519, as indicated previously by Bas Westerbaan from Cloudflare (https://lnkd.in/dB9pFCph). The authors (Sheran Lin, Jolene Tan, Ajanthan Asogamoorthy, Kyle Nekritz, Rafael Misoczki, PhD and Sotirios Delimanolis) report that Meta has deployed post-quantum hybrid key exchange for most internal service communication to protect against the SNDL threat already. However they recognize that implementing post-quantum hybrid key exchange to external public internet traffic poses several additional challenges, such as dependency on browsers’ TLS implementations and crypto libraries’ PQC readiness, increased communication bandwidth due to larger payloads, and more. We should thank all the different organizations sharing their experiences as they explore their way to transition to quantum-safe cryptography. This demonstrates it is not an easy task, but the accumulated experience shared by many will make it possible. https://lnkd.in/drJpMU4r

The era of quantum computing is closer than we think, and it’s going to change the foundations of digital security. NIST’s recent draft publication, NIST IR 8547 (link in 1st comment), outlines critical steps organizations must take to transition to post-quantum cryptography (PQC). Why This Matters Now ⏩ Quantum computers will eventually break traditional encryption algorithms like RSA and ECC. While secure today, these systems won’t be once quantum systems mature. NIST’s Post-Quantum Standards ⏩ NIST has selected algorithms like CRYSTALS-Kyber (for key establishment) and CRYSTALS-Dilithium (for digital signatures) to lead the transition. What Organizations Should Do ⏩ Inventory Cryptography: Assess where and how cryptographic algorithms are used. ⏩ Test PQC Algorithms: Experiment with hybrid solutions combining classical and quantum-safe algorithms. ⏩ Engage with Vendors: Ensure tech partners are preparing for PQC compatibility. Challenges Ahead ⏩ Performance trade-offs: Some PQC algorithms require more computational resources. ⏩ Interoperability: Integrating new cryptographic methods into legacy systems isn’t trivial. ⏩ Timeline pressure: The longer you delay, the harder it will be to catch up. The message is clear: preparation can’t wait. The organizations that start now will be in a much better position when the quantum era fully arrives.

Preparing for the Quantum Era: ** Top 5 CyberSecurity Considerations ** The advent of quantum computing brings unprecedented opportunities but also significant risks, particularly to traditional encryption and cybersecurity protocols. To future-proof against these challenges, organizations should consider the following key security measures: 1. Transition to Quantum-Safe Cryptography: Classical encryption algorithms, such as RSA and ECC, are vulnerable to quantum attacks. Organizations must start adopting quantum-resistant cryptographic standards, like those developed by NIST, to secure sensitive data for the long term. 2. Protect Data in Transit and at Rest: Quantum computers could render previously encrypted data vulnerable. Businesses should prioritize re-encrypting critical data with quantum-safe algorithms to mitigate risks. This will also mitigate the risk of “harvest-now, decrypt-later” attack which is a strategy in which a threat actor simply collects and stores encrypted data today with the intent of decrypting it with a sufficiently powerful quantum computer (when it is available) in the future. 3. Conduct a Post-Quantum Risk Assessment: Evaluate existing security frameworks to identify assets most at risk from quantum threats. A comprehensive assessment can guide the prioritization of upgrades to quantum-resistant solutions. 4. Invest in Quantum Security Research and Collaboration: Collaborate with industry consortia, government agencies, and academic institutions to stay informed about emerging quantum technologies and best practices. This approach ensures preparedness for future standards and advancements. 5. Educate and Train Staff: Equip your cybersecurity team with the knowledge and skills needed to implement and manage quantum-safe technologies. Training ensures the team is ready to handle the challenges posed by the quantum era. Organizations that proactively address quantum-era risks will position themselves as leaders in securing the next generation of data and communications. Acting now ensures long-term resilience against emerging threats. #QuantumComputing #Cybersecurity #QuantumResilience #PostQuantumSecurity #EncryptionFuture

Post Quantum Computing and Post Quantum Cryptography for 5G TLC a white paper by 5G Americas Organizations are recommended to develop plans for migration to PQC now, if they have not already started. Start by educating and informing key executives and stake holders on this topic and its urgency. Develop organizational roadmaps and migration plans, create a cryptographic inventory (including security protocols & versions) and perform quantum risk assessments. Prioritize assets most at risk of the “harvest now, decrypt later” attack or those assets that can cause the most damage if compromised. Investments into performance and interoperability testing, as well as cryptographic agility tools are recommended. Begin having conversations on quantum resistance with vendors, to understand and align your supply

Are federal agencies genuinely prepared for the quantum leap in cybersecurity? As quantum computing evolves from theoretical promise to practical reality, federal agencies must overhaul their IT infrastructure well before 2035. The challenge is clear: safeguard High-Value Asset (HVA) systems by migrating to post-quantum cryptography (PQC) to preempt quantum-enabled threats. The journey begins with a comprehensive inventory of assets. Federal agencies must meticulously catalog every hardware and software component that employs encryption—be it for remote access, authentication, or routine software updates. Central to this plan is establishing a secure testbed where quantum-resistant algorithms are rigorously evaluated. Testing these algorithms in simulated environments and research networks is critical to ensure they perform effectively, particularly given the larger key sizes that may affect bandwidth and latency. Adhering to federal standards—such as those from FIPS and the NSA’s Commercial National Security Algorithm Suite—is non-negotiable to ensure security and operational efficiency. Recent developments in the quantum space have underscored the urgency of innovation. Last week, Microsoft unveiled its latest quantum chip (Majorana 1), a breakthrough that redefines performance benchmarks and accelerates the need for robust, future-proof cybersecurity solutions. This milestone reinforces the imperative to continually innovate and adopt agile frameworks capable of evolving alongside emerging quantum technologies.
