|Horizon Europe〉Transition towards Quantum-Resistant Cryptography

Expected Outcome:

Projects are expected to contribute to at least three of the following expected outcomes:

  • Measuring, assessing and standardizing/certifying future-proof cryptography
  • Addressing gaps between the theoretical possibilities offered by quantum resistant cryptography and its practical implementations
  • Quantum resistant cryptographic primitives and protocols encompassed in security solutions
  • Solutions and methods that could be used to migrate from current cryptography towards future-proof cryptography
  • Preparedness for secure information exchange and processing in the advent of large-scale quantum attacks


During the next decades the European Union should seize the opportunities that quantum technologies will bring. However, quantum technologies will also pose a significant risk to the security of our society. The advent of large-scale quantum computers will compromise much of modern cryptography, which is instrumental in ensuring cybersecurity and privacy of the digital transition. Any cryptographic primitive based on the integer factorization and/or the discrete logarithm problems will be vulnerable to large-scale quantum-powered attacks. The digital data/products/systems that derive their security ultimately from the abovementioned primitives will be compromised and must be upgraded -including their replacement when needed- to quantum-resistant cryptography. The massive scale of this foreseen upgrade shows that preparations are needed today in order to widely implement the relevant mitigations in the future. Many companies and governments cannot afford to have their protected communications/data decrypted in the future, even if that future is a few decades away. There is a need to advance in the transition to quantum-resistant cryptography.
