As the world approaches the age of powerful quantum computers, traditional encryption methods face an impending risk. Markus Pflitsch, CEO of Terra Quantum AG, warns that quantum technologies will soon be able to crack any standard encryption method, posing a significant threat to data security. Introducing quantum-resistant cryptographic techniques such as post-quantum cryptography (PQC) and quantum key distribution (QKD) is crucial to prepare for this change. Pflitsch emphasizes that this is not just a technical challenge but also a question of national security.
The American National Institute of Standards and Technology (NIST) has announced new standards for security in a post-quantum world, highlighting the need to plan the transition to quantum-resistant cryptographic systems. Cross-border alliances and cooperation are essential to strengthening collective resilience against quantum-based threats. In Europe, Olaf Scholz’s recognition of quantum technology as a key technology is a welcome step. Still, more needs to be done to increase private investment in quantum start-ups and promote innovation.
The Quantum Age: New Threats and Opportunities
The advent of quantum technologies brings with it a plethora of opportunities but also new, complex threats that require immediate attention. Markus Pflitsch, a renowned quantum physicist and financial expert, emphasizes the need for preparedness in the face of emerging quantum-based security infrastructures.
The Gradual Risk of Quantum Computers
Pflitsch highlights that the closer we get to the age of powerful quantum computers, also called “Q-Day,” the more we face a progressive challenge for traditional encryption. It is not a one-time event where all encryption becomes suddenly obsolete, but rather a gradual improvement in the ability of quantum computers to crack widely used encryption algorithms. This underscores the importance of planning and transitioning to a quantum-resistant cryptographic system based on post-quantum cryptography (PQC) algorithms.
The “Hack-Now, Decrypt-Later” Attacks
One of the most acute dangers is the “hack-now, decrypt-later” attacks, where attackers can intercept and store encrypted data, knowing that quantum computers will be able to crack this encryption in a few years. This means that sensitive information that seems safe today can be endangered tomorrow, making awareness of these potential threats essential.
The Role of Quantum Key Distribution (QKD)
A comprehensive security strategy must also take into account the role of QKD, which offers additional security levels. QKD provides an ultra-secure method for encrypting and decrypting data, making it an essential component in the fight against quantum-based threats.
Cooperation: The Key to Mitigating Quantum Security Risks
Cooperation is crucial in identifying, evaluating, and mitigating future quantum security risks. However, countries are still largely isolated in their approach to cybersecurity, with cross-border alliances being rare. In many regions, people prefer to keep silent about attacks and threats rather than networking, exchanging ideas, and learning from incidents.
The Need for Cross-Border Cooperation
Without collaboration, we miss crucial opportunities to strengthen our collective resilience. To prepare ourselves sufficiently for the future of quantum technologies and combat risks in a targeted manner, we must promote greater cooperation, remove existing barriers, and work together across borders.
Securing Europe’s Sovereignty in the International Quantum Race
Olaf Scholz’s recognition of quantum technology as a key technology for Germany is a welcome step in the right direction. However, more needs to be done to ensure Europe catches up in the international quantum race and secures its sovereignty in the long term.
Europe must increase private investment in quantum start-ups, which are currently hindered by inadequate funding. Targeted financial incentives or the setting up of special quantum funds could promote innovation and integration of quantum technologies into the private sector.
Cross-border cooperation will determine Europe’s sovereignty in the international quantum race. Despite extensive government funding for quantum research in Europe, national initiatives often remain isolated. Countries such as France, Germany, and the Netherlands invest independently of one another, which can lead to Europe falling behind leading countries like the USA and China.
The Feasibility Study for a Quantum-Proof Network
The recently announced feasibility study for the US Air Force is a prime example of partnerships with high-level organizations preparing for the effects of quantum technologies. This project examines the feasibility of developing a quantum-resistant network for ultra-safe long-distance communication, mitigating the threat from “hack-now, decrypt-later” attacks.
The development of quantum-safe encryption methods is essential for data protection and ensures that secure communication of sensitive data can be guaranteed even if quantum computer capabilities progress. This project highlights the importance of quantum security for government and military institutions, especially those working with sensitive national security data.
