Laboratory task of the electronic access control system
Maňásek, Tomáš ; Zeman, Václav (referee) ; Burda, Karel (advisor)
The aim of this bachelor thesis is to study and describe access control systems. Based on the supplied components, design and implement an EKV system on the teaching panel. Design a laboratory task lasting 90 minutes for the created system and prepare documentation for students and the teacher for this task.
Block cipher mode of operation
Kunert, Alois ; Sikora, Marek (referee) ; Zeman, Václav (advisor)
This Bachelor thesis deals with Operation modes of symmetric ciphers. This thesis deals with both basic operation modes and with newer operation modes that offer additional functions. A conceptual design was made in semestral thesis, which was realised in this thesis. Finally an analysis of the basic operation modes, implemented in the web application ,was made to make a comparison between the measurments taken in the semestral thesis.
Stress tester
Lanžhotský, Karel ; Člupek, Vlastimil (referee) ; Zeman, Václav (advisor)
This bachelor thesis deals with the matter of stress testing using open-source tool Apache JMeter and it’s extensions. Main output is the extension of the module which allows to produce DoS (denial of service) attacks. At the beginning of the thesis, there are characteristics for this type of attack, what types of DoS exist with some examples. After that, there’s testing, verification of functionality and finding of errors in extension modules. At the end thesis is dedicated to adding features to DDoS module and testing of capabilities of the attacks on created scenarios.
Digital identity
Dvořák, Roman ; Burda, Karel (referee) ; Zeman, Václav (advisor)
This bachelor‘s thesis deals with the personal digital identity area. Its goal is to describe accompanying technologies which ensure the course of this field. In addition, another goal is to describe the state of things in related sectors. At first, attention is focused to basic concepts and terms describing this topic. The following section describes technologies which are used in area of digital and bank identity. In the next chapter, the emphasis is on explaining terms linked with digital identity and the structure of public eGovernment, followed by the description of e-identity. In this chapter, the identification means, provided by the government or commercial sector, are more explained. The same applies to the identification means provided by the government, but which are not considered as e-identity. Another chapter is dedicated to European Digital Identity and its current state, followed by mentioning states which have used digital identity before it was made mandatory by the regulation from European Commission. The following chapter explores security threats, their enumeration and classification according to different criteria. It mentions types of cyberattacks, threats associated with using digital identity and elimination of the threats. The point of view is taken from user’s experience, but from providers as well. The last chapter describes the practical part which is an educational web application that summarizes the output of this bachelor’s thesis.
Comparison of cryptography performance of microcontrollers ARM Cortex-A
Škurla, Tomáš ; Zeman, Václav (referee) ; Slavíček, Karel (advisor)
The bachelor thesis deals with the measurement of cryptographic performance of ARM Cortex-A series microcontrollers. The theoretical part focuses on the description of concepts of cryptography, while at the same time explaining the principles of operation of individual cryptographic systems. Afterwards, thesis also describes the inner workings of ARM processors, their historical development, support for cryptography and detection of said support within processors. This is followed by defining the metrics for testing, part of which includes enumerating the hardware used in the testing process, with the focus being on the cryptography acceleration and encryption support. This also includes a description of the planned environment and software used in the testing. The practical part includes a description of the actual preparation of the defined environment and its possible modifications within the individual testing needs. The thesis concludes with an evaluation of the processed data and subsequent drawing of conclusions
Intelligent beekeeping system
Hrubý, Jan ; Zeman, Václav (referee) ; Kiac, Martin (advisor)
The aim of this thesis is to design and develop an intelligent beekeeping system that can measure the frequency in the colony, the weight of the hive to monitor the loss or to inform the beekeeper if the bees are carrying honey. Furthermore, the security of the hive against theft is also being considered. Communication between multiple intelligent beekeeping systems is important for the functionality. This is why part of the work focuses on choosing the best possible communication, taking into consideration battery consumption and reliability. In this work, a many-to-one communication system of modules is used, which means that the number of hives can be freely expanded without affecting the functionality of the system. The resulting system is powered by a combination of battery and solar panels.
Network probe
Skočdopole, Jan ; Člupek, Vlastimil (referee) ; Zeman, Václav (advisor)
The diploma thesis deals with load testing and its use in computer security. The goal of this thesis was implementing new functionality in existing solution based on Apache JMeter load testing tool. Next goal was verification of possibility of running testing tool on another operating system and update of documentation. PDF export with electronic signature support shod be implemented in the Network Analyzer plug-in. The Apache PDFBox library was used in this work. Result of thesis is new functionality of export to PDF format with electronic signature support, updated documentation and fix of some module bug.
IoT system for factory energy consumption optimization
Čuhel, Radim ; Zeman, Václav (referee) ; Slavíček, Karel (advisor)
This work deals with the measurement of electricity consumption in the production plant Draka Kabely in Velké Meziříčí. The main solution to the problem in the theoretical part is a description of the general distribution of electricity in the Czech Republic, a description of the production plant and the measurement of electricity together with the principles of regulation of measured energy. The practical part of the work is focused on the implementation of measuring sensors in the corporate network model. Setting and commissioning of sensors together with the possibilities of regulating the consumed energy. The result of this work will be used to improve the regulation and use of electricity in the production plant.
Interdisciplinary research of medieval sacral architecture
Derner, Kryštof ; Havrlant, Jaroslav ; Křivánek, Roman ; Kuljavceva Hlavová, Jana ; Lissek, Petr ; Peksa, Vojtěch ; Skopec, Jaroslav ; Václavík, František R. ; Witan, Joanna ; Zeman, Václav
The methodology is divided into three basic areas of the cognitive process of sacral architecture, which differ according to the nature of the studied sources. I. Problems of knowledge of sacral architecture on the basis of written, cartographic and pictorial sources. II. Sacral architecture in terms of material sources of archaeological nature (artifacts, ecofacts and their finds). III. Sacral architecture on the basis of material sources of a building nature, examined by a building historical survey. These areas are accompanied by subchapters devoted to other methods, other cognitive and documentation processes. A necessary part are also small excursion chapters, in which specific examples from research practice are described.
