Quantum computing has the potential to address urgent global challenges, such as climate change and food security. However, as large-scale quantum computers develop, we must be aware of the risks they pose, including the potential to compromise cryptographic algorithms, secure communications and digital identities.

Quantum & Security Balance

Quantum Security Balance

Quantum computing is set to revolutionise various fields by addressing some of the world’s most complex challenges, including climate change, food security, and medical research. However, this transformative potential brings a significant challenge: the ability to break traditional cryptographic algorithms that safeguard secure communications, financial transactions, and sensitive data. As large-scale quantum computers become a reality, it is crucial to ensure responsible development, implement robust security measures, and explore quantum-resistant encryption methods to balance innovation with cybersecurity. By proactively addressing these risks, we can harness the full benefits of quantum computing while protecting the global digital infrastructure

The Risks

While quantum computing offers groundbreaking possibilities, it also poses risks, particularly to cryptographic security. As these powerful systems evolve, they could break encryption that protects sensitive data, financial transactions, and secure communications. Proactive security measures are essential to mitigate these threats.

 

 

Impossible becomes possible

Today, most data transmitted over the internet-whether for online commerce or WiFi access-is safeguarded by public key cryptography. Breaking this encryption would take the most powerful classical computers thousands of years. However, a scaled quantum computer leveraging Shor’s algorithm could theoretically crack these complex mathematical problems in just a few hours, exposing your sensitive information to significant risk.

 

 

Encrypted Data Harvesting

If encrypted data is stolen by hackers today, will it still matter in 10 years when scaled quantum computers become available? For most data, relevance diminishes over time. Identifying which data and critical systems need immediate protection is a crucial first step toward a quantum-safe future. Transitioning to quantum-safe cryptography is a complex process that requires time, and the time to start planning is now.

 

The Journey to a Quantum-Safe Future

Simplified Security is committed to building a quantum-safe future by securing products, services, customers, partners, and entire supply chain. Our efforts focus on achieving cryptographic agility, adopting hybrid solutions, and integrating standardized post-quantum cryptographic algorithms. Additionally, we are strengthening security processes through specialized services and comprehensive training to ensure robust protection against emerging quantum threats.

The Process – Migration from traditional PKI to PQC

We provide end-to-end PCI DSS compliance services, starting with a gap analysis and risk assessment to identify security weaknesses. Our team develops a tailored strategy, assists with implementation, and conducts staff training. A mock audit ensures you’re prepared for certification, with continuous support throughout the process.

Assess and Plan

Inventory and assess current RSA usage across all critical systems and data. Evaluate data sensitivity, lifespan, and third-party dependencies. Research and understand NIST-recommended PQC algorithms, such as CRYSTALS-Kyber and CRYSTALS-Dilithium. Develop a phased migration plan prioritizing high-risk systems.

Build Agility

Implement cryptographic agility to facilitate seamless integration of new PQC algorithms. Utilize hybrid approaches combining classical and PQC for backward compatibility.

Test and Validate

Pilot PQC algorithms in controlled environments to evaluate performance and compatibility. Rigorously test the strength of selected algorithms against potential quantum threats.

Transition and Upgrade

Update hardware, software, and key management systems to support PQC requirements. Collaborate with vendors and partners to ensure compatibility and alignment with industry standards.

Monitor, Adapt, and Educate

Continuously monitor PQC performance and adapt to evolving quantum threats and refined standards. Train teams on PQC and its implications, ensuring all stakeholders are informed. Stay proactive in researching and implementing the latest advancements in quantum-safe cryptography.
