\section*{List of Other Contributions}

Throughout and before my PhD studies, I also contributed to the following:

\begin{itemize}
  \item The Sigsum Project.
    \url{https://www.sigsum.org/} (2020-present).

    Sigsum is a free and open-source software project that brings transparency
    to signed checksums.  The design is simple and uses a proactive gossip-audit
    model.  I founded Sigsum with Linus Nordberg and Fredrik Str\"{o}mberg while
    working at Mullvad VPN as a side-line occupation.

  \item Tobias Pulls and \textbf{Rasmus Dahlberg}.
    Steady:
    A Simple End-to-End Secure Logging System.
    NordSec (2018).

    Tobias was the main driver.  I mostly contributed with design discussions
    and a security formalization.

  \item \textbf{Rasmus Dahlberg}, Tobias Pulls, and Roel Peeters.
    Efficient Sparse Merkle Trees:
    Caching Strategies and Secure (Non-)Membership Proofs.
    NordSec (2016).
    
    This work started with my Bachelor's thesis.  I did most writing with
    input from Tobias and Roel.  Tobias did our benchmarking experiments.

  \item \textbf{Rasmus Dahlberg} and Tobias Pulls.
    Standardized Syslog Processing:
    Revisiting Secure Reliable Data Transfer and Message Compression.
    Technical Report, Karlstad University (2016).

    I was the main driver.  Tobias contributed with continuous feedback.
