Applied Cryptography in IoT
Ilyushchenkov, Maxim ; Martinásek, Zdeněk (referee) ; Malina, Lukáš (advisor)
The bachelor thesis is devoted to security in IoT systems. The thesis describes the IoT architecture, how to ensure its security and various types of attacks on IoT devices. Subsequently, the protection of personal data IoT and solutions for its protection are described. The work also describes the MQTT technology, its principle of operation, architecture and basic elements. The practical part describes the implementation of the publisher and subscriber, who communicate using encrypted messages. Afterwards, the eciespy library is described, which enables encryption and decryption of messages. The method of communication between the server and the client using the TLS protocol and certificate exchange is also described. Finally, there is a solution for implementing secure communication between microcomputers using MQTT.

New synagogue in Trutnov
Rudolecká, Anna ; Benedek, Borislav (referee) ; Dulenčín, Juraj (advisor)
The assignment of the diploma thesis was the elaboration of an architectural study of a new synagogue in the town of Trutnov, on the site of the original Jewish synagogue, which was burned down during the November pogrom, the so-called Crystal Night in 1938. Nowadays, the synagogue area is modified and serves as a place of reverence to honour the memory of the victims and to commemorate these historical events. The result of the design is a new community centre. Its goal is to restore the existence and support the development of the Jewish community, which disappeared in Trutnov after the Second World War. In the area there is the seat of the Jewish community, a ritual cleansing bath Mikveh, Kosher restaurant and a new synagogue, which respects the location of the former synagogue on the site of the original foundations. The new Jewish community centre ensures the operation of the entire Jewish community in Trutnov. Part of the Jewish community centre is a large courtyard, which is used to celebrate Jewish holidays and also as a summer terrace for Kosher restaurant, which will be used by the Jewish community, but also by the inhabitants of Trutnov. This creates an attractive place to spend free time with a view of the nearby Giant Mountains and the historic centre of Trutnov, but at the same time it is protected from the bustle of the adjacent main street.

The new synagogue in Frýdek-Místek
Večeřová, Pavla ; Velek, Jan (referee) ; Dulenčín, Juraj (advisor)
The assignment of the diploma thesis was the elaboration of an architectural study of a new synagogue in the Frýdek-Místek. The solved area includes the original lands of the Jewish community, on which stood a synagogue, a Jewish school and a rabbinate. The synagogue was burned down in 1939 and currently only the rebuilt Jewish school building is located in the area. The main idea of the design is to build a memorial on the site of the original synagogue and a new synagogue with an adjoining community centre. The main goal is to support the development of the Jewish community in the city and to remind citizens and visitors of the history, because of which the Jewish community in Frýdek-Místek disappeared. In contrast to the monument, the entire building is set in the terrain so that the terrain passes freely in a public space with the main entrance to the community centre and a kosher restaurant. The building opens up to the south side of the slope and offers a view of the historic city centre of Frýdek. The area is connected by a footbridge to the park under the castle. Part of the community centre is a space for a ritual bath - Mikveh, the administration of the Jewish community and a multifunctional hall, which can be opened to the area in front of the residential staircase. The area is separated from Revoluční Street by a retaining wall and thus form an attractive place to spend time near the historic centre.

New synagogue in Opava
Gracová, Michaela ; Velek, Jan (referee) ; Dulenčín, Juraj (advisor)
The subject of the diploma thesis was the elaboration of an architectural study of a new synagogue in Opava, which, with other necessary objects, will create a complex used by the jewish community and its members. The result of the design is a new community center. This has the task of restoring existence and supporting the development of the jewish community, which has not found its way back to Opava since world war II. Three separate objects cover the needs of this community for everyday and spiritual life. This includes education taking place in the library, the seat of the jewish community and its leaders, ritual cleansing areas of the mikveh and the commercial space of the kosher food or products store. It is necessary to have a kosher restaurant providing proper eating. An important part is also the space of cultural activities in the form of artistic or other exhibitions and events. The main area of the complex is a synagogue where prayers, festivities and meetings are held.

Applied Cryptography in IoT
Ilyushchenkov, Maxim ; Martinásek, Zdeněk (referee) ; Malina, Lukáš (advisor)
The bachelor thesis is devoted to security in IoT systems. The thesis describes the IoT architecture, how to ensure its security and various types of attacks on IoT devices. Subsequently, the protection of personal data IoT and solutions for its protection are described. The work also describes the MQTT technology, its principle of operation, architecture and basic elements. The practical part describes the implementation of the publisher and subscriber, who communicate using encrypted messages. Afterwards, the eciespy library is described, which enables encryption and decryption of messages. The method of communication between the server and the client using the TLS protocol and certificate exchange is also described. Finally, there is a solution for implementing secure communication between microcomputers using MQTT.

Comparison of public key cryptography algorithms
Mareš, Jiří ; Stanovský, David (advisor) ; Žemlička, Jan (referee)
In the present work we study comparison of basic public key encryption algorithms - RSA, Rabin and ElGamel method. We derive theoretic complexity of encrypting / decrypting of one block and we derive an expected model of its behavior with the key of double size. We also take practical measurements of speed of each algorithm using keys sized 64 - 4096 bits and we statistically analyze the results. We also mention special cases of some algorithms and discuss the advantages and disadvantages of their practical usage. At the end of this thesis we make a comparison of the speed of algorithms and we also compare the measured data with theoretical hypothesis.
