bpK#: Delegatable Pseudonyms And Their Applications to National eID Systems
Stephan Krenn, Doryan Lesaignoux, Sebastian Ramacher
Electronic identities (eIDs) are crucial in an increasingly digitalized environment. Pseudonyms, as offered by Austria's governmental sector-specific personal identifiers (bPks), c…
Towards National Quantum Communication in Europe: Planning and Sizing Terrestrial QKD Networks
Sebastian Raubitzek, Werner Strasser, Sebastian Ramacher +3
The European Union is developing the European Quantum Communication Infrastructure (EuroQCI) as a pan-European network to provide secure communication capabilities across Member St…
PQC-Enhanced QKD Networks: A Layered Approach
Paul Spooren, Andreas Neuhold, Sebastian Ramacher +1
We present a layered and modular network architecture that combines Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) to provide scalable end-to-end security acros…
Topology-Hiding Path Validation for Large-Scale Quantum Key Distribution Networks
Stephan Krenn, Omid Mir, Thomas Lorünser +2
Secure long-distance communication in quantum key distribution (QKD) networks depends on trusted repeater nodes along the entire transmission path. Consequently, these nodes will b…
Commitment Schemes from OWFs with Applications to Quantum Oblivious Transfer
Thomas Lorünser, Sebastian Ramacher, Federico Valbusa
Commitment schemes are essential to many cryptographic protocols and schemes with applications that include privacy-preserving computation on data, privacy-preserving authenticatio…
Quantum-Safe Hybrid Key Exchanges with KEM-Based Authentication
Christopher Battarbee, Christoph Striecks, Ludovic Perret +2
Authenticated Key Exchange (AKE) between any two entities is one of the most important security protocols available for securing our digital networks and infrastructures. In PQCryp…
Extending Expressive Access Policies with Privacy Features
Stefan More, Sebastian Ramacher, Lukas Alber +1
Authentication, authorization, and trust verification are central parts of an access control system. The conditions for granting access in such a system are collected in access pol…
Privacy-preserving Analytics for Data Markets using MPC
Karl Koch, Stephan Krenn, Donato Pellegrino +1
Data markets have the potential to foster new data-driven applications and help growing data-driven businesses. When building and deploying such markets in practice, regulations su…
Short-Lived Forward-Secure Delegation for TLS
Lukas Alber, Stefan More, Sebastian Ramacher
On today's Internet, combining the end-to-end security of TLS with Content Delivery Networks (CDNs) while ensuring the authenticity of connections results in a challenging delegati…
On v-Marot Mori rings and C-rings
Alfred Geroldinger, Sebastian Ramacher, Andreas Reinhart
C-domains are defined via class semigroups, and every C-domain is a Mori domain with nonzero conductor whose complete integral closure is a Krull domain with finite class group. In…
