Security Research

Security Research

Peer-reviewed research on network security, privacy, and anonymity systems — backed by hands-on security engineering for production deployments.

Konza Labs conducts and consults on applied security research. The work below concentrates on the security and privacy of network systems — the Tor anonymity network, transport and web security, and network measurement. We take pride in our analysis so that it survives contact with real adversaries and real deployments.

If your organization needs a security review, a measurement study, or research that ends in shipped code rather than a slide deck, that’s the kind of work Konza Labs takes on.

Matt Traudt

Founder & Principal — the sole member of Konza Labs

Matt's security work spans the Tor anonymity network, web PKI and transport security, and network measurement. Before founding Konza Labs he conducted research at the U.S. Naval Research Laboratory and collaborated with the Tor Project and academic partners — work that produced the peer-reviewed publications below and shipped code that runs in the live Tor network today.

Software & practice

Research at Konza Labs doesn't stop at the paper. Selected work that shipped and ran in production:

  • KIST scheduler — a socket-transport scheduler merged into Tor 0.3.2.9 that prioritizes low-bandwidth, bursty web traffic over bulk transfers.
  • sbws (Simple Bandwidth Scanner) — a maintained replacement for Tor's legacy bandwidth-measurement tooling, used by directory authorities to weight relay selection.
  • FlashFlow — a secure relay speed-testing design and prototype for the Tor network.
