PQC visualizations
Post-Quantum Cryptography (PQC) is the field of developing new security tools that can withstand the power of future quantum computers. Today, most of the digital world including online banking, private messaging, software updates, etc. relies on mathematical problems that are safe against ordinary computers but could be solved quickly by a sufficiently strong quantum computer. PQC designs new key exchange mechanisms and digital signatures that rely on different kinds of hard mathematical problems, ones that experts believe will remain secure even in a quantum era. Governments and standards bodies around the world are now preparing to adopt these new protections so that the information we rely on today will still be safe tomorrow.
At the Applied Cyber Security Research Lab at Lucerne University of Applied Sciences and Arts, we are exploring the potential of PQC and its applications in securing digital communications against future quantum threats.
PQC Digital Signatures Visualization
As part of a project with essendi it AG and an internal collaboration with the Information Visualization group we developed an interactive website to show the most relevant characteristics of the new PQC digital signature algorithms. Users can filter algorithms by keys or certificates sizes and by the performance of the algorithms in different operations (key generation, signing, verification).
The website is regularly updated to include novel algorithms. The visualization will be presented as a demonstration at the ETSI Security Conference 2025.

}PQC TLS 1.3 Benchmark Visualization
The new PQC digital signatures will have an impact in many protocols. In particular, the amount of data transmitted during the TLS handshake will increase significantly. As part of a project in collaboration with Securosys and an internal collaboration with the Information Visualization group, we worked on visualizing the impact of PQC on TLS 1.3 handshakes.
The website has since been updated to include novel signature algorithms, results will be presented as poster at the ETSI Security Conference 2025.

liboqs 0.14.0 and a benchmarking app. The network simulation was done using Linux network namespaces
and NetEm.
