QCI-CAT

As a cornerstone for data autonomy, data security has become a fundamental necessity. With regards to the public sector
and critical infrastructures, it safeguards economic competitiveness and sustainable national security. Technological
breakthroughs in the form of quantum computers threatens our current encryption methods, therefore, developments
of novel encryption technologies and systems that are proven to be “quantum-safe” are necessary. The importance of
data security is underpinned by the 10-years research and innovation program “EuroQCI Quantum Communication
Infrastructure”. Building on the long research experience of Austrian institutions in the field of quantum technologies,
the project QCI-CAT aims at an adoption of modern encryption technology based on QKD (Quantum Key Distribution)
for highly secure communication between public authorities. For this purpose, a QKD demonstration network will
be installed in Vienna, which will connect the Federal Chancellery (BKA) as a central node with three other federal
ministries BMLV, BMEIA and BMK. Building on a close cooperation between research partners and industrial
companies, QCI-CAT will investigate and verify new security applications for public authorities, such as secret sharing
and message authentication. Close cooperation between stakeholders ensures that the development of QKD-based
security technology is driven from viewpoint of an IT end-user. QCI-CAT will also leverage a test and demonstration
infrastructure to research new technological approaches such as the combination of post-quantum encryption technology
with QKD, long-distance QKD with secured trusted nodes and field trials of quantum repeaters. Moreover, the results
of QCI-CAT will constitute the basis for the strong positioning of Austria within the European EuroQCI initiative. The
outcomes will also be shared with other neighboring countries and built upon with planning of cross-border links for
a fully connected EuroQCI.
