Developing quantum-safe protocols

research led to the development of quantum-secure handshake protocols that ensure digital connections remain safe from quantum-powered attacks.

For example, she redesigned the popular WireGuard VPN protocol to create PQWireGuard, a version resistant to quantum threats.

She also extended the Noise framework, widely used for secure communication, by incorporating quantum-resistant features. These advancements provide developers with practical tools for building secure communication channels that are ready for the challenges of the quantum era.

Safeguarding satellite communications

In collaboration with the European Space Agency (ESA), she developed a secure protocol to protect communications between satellites and mission control centers.

Her research significantly strengthened the security of these crucial links and laid the foundation for secure satellite-to-satellite communication. This work addressed the unique challenges of space communication, ensuring it can remain resilient in the face of emerging quantum technologies.

Enhancing privacy in group chats

°Â±ð²ú±ð°ù’s research also focused on privacy in online communication. She introduced epochal signatures, which allow group chats to be deniable, which means that there is no cryptographic proof to confirm whether a conversation really happened.

This helped to preserve privacy while maintaining the integrity of messages.

Key outcomes

°Â±ð²ú±ð°ù’s work conclusively demonstrated that handshake protocols can be made secure against quantum threats.

Additionally, she proved that digital communication systems can be designed to offer plausible deniability, allowing privacy decisions to be guided more by social and political factors, rather than just technical feasibility.

A legacy of secure communication

By blending cutting-edge theory with practical implementation, °Â±ð²ú±ð°ù’s research helps to shape a digital future that is both secure and respectful of privacy.

Her work has shown that, no matter how technology evolves, the tools designed to protect communication systems will remain robust, trustworthy, and prepared for the challenges of the quantum era.
