+<h2>Abstract</h2>
 <p>
 The goal of this thesis is to improve Taler’s performance and provide cipher 
agility by
 adding support for Schnorr’s blind signatures. To achieve this goal, the 
current state in
 research for Schnorr signatures needs to be analyzed. After choosing a 
signature scheme,
-it has to be integrated into the Taler protocols. Besides implementing the 
redesigned pro-
-tocols in Taler, an implementation of the cryptographic routines is needed.

Algebraic Group
-Model” from 2019 (updated in 2021) introducing Clause Blind Schnorr Signatures

 is used as theoretical basis for our improvements. The paper explains why

scheme is se-

 All of the implemented code is tested and benchmarks are added for the 
cryptographic
 routines.

 between RSA Blind Signatures and Clause Blind Schnorr Signatures. Overall, the 
Clause
 Blind Schnorr Signatures are significantly faster, require less disk space, 
and bandwidth
 and provide cipher agility for Taler.
