SS05 – Special Session on Cybersecurity in a Hybrid Quantum World


Quantum computers have provided many headlines during the last years. With their promise to solve mathematical problems faster than any computer currently in existence, the possibility of having this type of technology represents both a blessing and a menace. In the field of cryptography, quantum computing is expected to break most of the currently used cryptographic algorithms, specially public-key designs, so the academic community has been working on quantum-resistant and quantum-safe cryptography. Moreover, organizations such as NIST and ETSI have specific working groups to advance algorithms, primitives and risk management practices to withstand the advent of quantum computers.

However, despite all the hype associated with quantum technology, practical computers that can be used for breaking highly secure systems are not expected to be accessible in the near term. This means that, in the next years, implementations will be developed in a hybrid world in which pre-quantum and quantum algorithms will coexist.

This special session welcomes theoretical and applied contributions that address algorithms, technologies and practices that are expected to coexist in the next years until quantum computing is a complete reality.


The list of possible topics includes, but is not limited to:

  • Post-quantum cryptography.
  • Coexistence of pre-quantum and post-quantum technologies.
  • Analysis of technology impacted by quantum computing.
  • Blockchain innovation focused on quantum-resistance and new areas of application.
  • New proposal for technologies that can be deployed now and survive the advent of quantum computers.
