Modern Privacy-Preserving Cryptography Protocols
Hlučková, Pavla ; Dzurenda, Petr (referee) ; Malina, Lukáš (advisor)
This thesis examines the intersection of two modern and growing branches of cryptography, namely privacy enhancing technologies and post-quantum cryptography. It describes selected privacy enhancing schemes (PETs) and families of post-quantum cryptography. In more detail, it focuses on group signatures based on mathematical problems that are difficult or intractable for both conventional and quantum computers. Furthermore, the thesis surveys the state of the art and compares the efficiency of mentioned schemes based on available data. The main part of this thesis is an implementation of a hash-based group signature and its comparison with lattice-based and code-based group signature implementations which were obtained directly from cryptographers active in this field. The post-quantum group signatures are subsequently compared to classic group signature schemes implemented by using the libgroupsig library.

Design of Methods for Encrypted Traffic Visualization
Hlučková, Pavla ; Martinásek, Zdeněk (referee) ; Malina, Lukáš (advisor)
This thesis deals with design of methods for encrypted traffic visualization. It generally describes selected encrypted traffic protocols, whose data samples were collected later on to form a dataset. Furthermore, it focuses on the topic of IP flow monitoring and decribes the means of carrying out such monitoring. An important part of this thesis is the dataset created from the samples of mentioned protocols and the visualizations of different statistics and metadata gatherable from (extended) IP flows of these protocols. The designed methods of visualization are implemented using the Python programming language and the Jupyter Notebook technology.
