Germany Launches Quantum-Secure ID Card Demonstrator

Bundesdruckerei GmbH and Giesecke+Devrient (G+D), in collaboration with the German Federal Office for Information Security (BSI) and Infineon, have demonstrated a functional prototype of a quantum-secure national ID card announced November 11, 2025. The demonstrator integrates a specialized chip implementing a hybrid cryptographic scheme, combining established algorithms with post-quantum cryptography (PQC) to safeguard against future attacks from quantum computers. This preemptive approach addresses the ten-year validity period of German ID cards, ensuring long-term security by adopting PQC for digital signatures and authentication, representing one of the world’s first such implementations at a national level.

Germany Pioneers Quantum-Resistant ID Card Technology Germany is taking a proactive step toward future-proof security with the development of quantum-resistant ID cards. Bundesdruckerei and G+D, alongside the BSI and Infineon, have created a demonstrator utilizing post-quantum cryptography (PQC). This initiative addresses the looming threat of quantum computers breaking current encryption standards—algorithms vulnerable to attacks potentially arriving by 2030. The new cards integrate PQC algorithms onto specialized Infineon chips, ensuring data remains secure even against advanced computational capabilities. This isn’t simply theoretical work; Germany is preparing for a practical transition. The approach is two-phased, starting with quantum-resistant digital signatures and progressing to full PQC implementation. Given the ten-year validity period of ID cards, preemptive action is crucial. This demonstrator represents one of the first functional national ID card implementations combining classical and post-quantum cryptography, aligning with EU roadmap recommendations for PQC adoption in critical infrastructure. The core challenge lies in integrating resource-intensive PQC algorithms onto the limited processing power of ID chips.

The team overcame this by designing new chip architectures, enabling fast and secure software implementation. This pioneering work establishes Germany as a leader in safeguarding sovereign documents against future quantum threats, and demonstrates a commitment to digital sovereignty within Europe and beyond. Implementing Post-Quantum Cryptography for Secure IDs Germany is pioneering the implementation of post-quantum cryptography (PQC) in its national ID cards, anticipating the threat posed by future quantum computers. A demonstrator project, led by Bundesdruckerei, G+D, the BSI, and Infineon, successfully integrated PQC algorithms onto ID chips. This proactive approach addresses the vulnerability of current cryptographic systems—like those used for key exchange and digital signatures—to attacks from sufficiently powerful quantum computers, ensuring the long-term security of sensitive citizen data. Each ID card has a ten-year validity, necessitating this forward-looking security upgrade. The transition to PQC isn’t simply a software update; it requires specialized hardware and optimized algorithms. Infineon chips used in the demonstrator were designed to support fast, side-channel-resistant implementation of resource-intensive PQC. This is critical because minimizing the computational footprint is a significant challenge. The EU roadmap targets PQC adoption in critical applications by 2030, and Germany aims to be prepared, acknowledging that quantum computers capable of breaking existing encryption could arrive within that timeframe. This project represents a crucial step toward safeguarding digital identities in the quantum era. Germany’s early adoption of hybrid PQC – combining classical and quantum-resistant methods – sets a new standard for secure ID documents. Leveraging experience from projects like Aquorypt and Quoryptan, the collaboration showcases the feasibility of integrating PQC into sovereign documents, protecting them against potential attacks and maintaining public trust in digital identification systems for years to come. Addressing Threats from Quantum Computing Advances Germany is proactively addressing the threat quantum computing poses to digital security, demonstrated by a new quantum-secure ID card. Current cryptographic algorithms, relied upon for secure data transmission and storage, are vulnerable to attacks from sufficiently powerful quantum computers—specifically, algorithms like Shor’s algorithm can break widely used public-key encryption. The demonstrator card utilizes post-quantum cryptography (PQC) – algorithms believed to be resistant to both classical and quantum attacks – ensuring long-term data protection, given ID cards typically remain valid for ten years. This initiative isn’t simply theoretical; it’s a staged implementation. The first phase integrates quantum-resistant digital signatures, while the second will fully transition to PQC. Key to this advancement is collaboration between Bundesdruckerei, Giesecke+Devrient (G+D), the Federal Office for Information Security (BSI), and Infineon. The project highlights the urgency of PQC adoption, anticipating that quantum computers capable of breaking current systems could emerge by 2030 – aligning with the EU’s roadmap for PQC in critical applications. Implementing PQC on resource-constrained devices like ID chips presents technical challenges. The Infineon chips used in the demonstrator feature a design optimized for fast, side-channel-resistant implementation of these computationally intensive PQC algorithms. This isn’t just about if quantum computers will pose a threat, but when. Germany’s pioneering work ensures a future where secure digital identities remain protected even in the face of rapidly advancing quantum computing capabilities, setting a global standard for sovereign document security.

Partnership Drives Innovation in Digital Security Germany is pioneering the next generation of secure ID cards, proactively preparing for the advent of quantum computing. A collaborative effort between Bundesdruckerei, Giesecke+Devrient (G+D), the Federal Office for Information Security (BSI), and Infineon has yielded a demonstrator integrating post-quantum cryptography (PQC). This crucial step addresses the looming threat to current encryption methods – specifically algorithms vulnerable to attacks from sufficiently powerful quantum computers – ensuring the validity of ID cards, typically issued for ten years, isn’t compromised. The demonstrator utilizes specialized Infineon chips designed to support fast and secure implementation of PQC algorithms. This isn’t simply theoretical; the project implements a hybrid approach, combining existing cryptographic standards with quantum-resistant alternatives. This staged transition is vital, as the EU aims for PQC adoption in critical applications by 2030, anticipating quantum computers capable of breaking today’s encryption by that timeframe. The BSI emphasizes Germany’s leading role in safeguarding sovereign documents. Minimizing the computational burden of PQC is a key technical achievement. Resource-intensive algorithms have been successfully integrated onto ID chips without compromising performance. This collaboration builds on previous successes, including a quantum-resistant electronic passport demonstrator developed in 2022. The project highlights the importance of public-private partnerships in addressing complex cybersecurity challenges and proactively fortifying digital infrastructure against future threats.
