\chapter{Installation}
These installation instructions are meant to run the code developed within this thesis for development- and review-purposes.
For a comprehensive installation instruction follow the Taler documentation
\cite{taler-documentation}.
\begin{bfhNoteBox}
These instructions are used and tested on Ubuntu 21.10.
\end{bfhNoteBox}
\section{Dependencies and Setup}
The following dependencies need to be installed for GNUnet and Taler Exchange:
\setupLinuxPrompt{student}
\begin{ubuntu}
sudo apt update
sudo apt install git curl build-essential gcc automake make \ texinfo autoconf uncrustify libtool pkgconf gettext gnutls-bin \ libcurl4-gnutls-dev libgcrypt20-dev libidn2-dev libjansson-dev \ libnss3-dev sqlite pipenv libltdl-dev libsodium-dev libpq-dev \ autopoint libunistring-dev libextractor-dev libpng-dev \ libpulse-dev libsqlite3-dev recutils python3-jinja2 sqlite yapf3 \ postgresql libpq-dev wget libmicrohttpd-dev
export LD\_LIBRARY\_PATH=/usr/local/lib
\end{ubuntu}
\begin{bfhBox}[BFH-MediumBlue]{Install in a container}
The installation can also be done in a docker or podman container with the ubuntu:21.10 image:
\setupLinuxPrompt{student}
\begin{ubuntu}
podman run -it --name talertest ubuntu:21.10
\end{ubuntu}
\end{bfhBox}
\section{Install GNUnet Core}
GNUnet core is both a dependency of the Taler exchange and where we implemented the Clause Blind Schnorr Signature Scheme.
\setupLinuxPrompt{student}
\begin{ubuntu}
git clone https://git.gnunet.org/gnunet.git
cd gnunet
./bootstrap
./configure --enable-benchmarks --prefix=/usr/local
make
make install
make check # Run optionally to verify installation and run tests
\end{ubuntu}
To run benchmarks run:
\setupLinuxPrompt{student}
\begin{ubuntu}
./src/util/perf_crypto_cs
./src/util/perf_crypto_rsa
\end{ubuntu}
\section{Install Taler Exchange}
\begin{bfhWarnBox}
Ensure that the current user has privileges in postgresql.
One possible way to do this is:\\
(where [user] has to be replaced with the name of the system user running the tests)
\setupLinuxPrompt{student}
\begin{ubuntu}
service postgresql start
sudo su
su - postgres
psql
CREATE ROLE [user] LOGIN SUPERUSER;
CREATE DATABASE [user] OWNER [user];
exit
\end{ubuntu}
\end{bfhWarnBox}
The Taler exchange can be installed as followed:
\setupLinuxPrompt{student}
\begin{ubuntu}
service postgresql start
createdb talercheck
git clone https://git.taler.net/exchange.git
cd exchange
./bootstrap
./configure --with-gnunet=/usr/local --prefix=/usr/local
./make
./make install
./make check # Run optionally to verify installation and run tests
\end{ubuntu}
To execute the security module benchmarks run:
\setupLinuxPrompt{student}
\begin{ubuntu}
cd src/util
./test_helper_cs
./test_helper_rsa
\end{ubuntu}

\section{Performance of the Security Module}
These performance measurements are only done on one hardware setup.
The performance tests of the cryptographic routines are more meaningful, the architecture of the Taler exchange could change a lot.
Furthermore, there could be made performance improvements at costs of security by doing the operations requiring the private keys directly in the httpd process.
Because of security reasons, the current design with the security module makes a lot of sense.
It has to be kept in mind that the following performance benchmarks are interesting to see, but could vary a lot with changes inside the codebase.
The performance of the signatures with the security module can be found in table \ref{tab:comp-sign-full}
