Software and Hardware Based Fault Injection Attacks against the CPU and MCU
Lörinc, Marek ; Hanáček, Petr (referee) ; Perešíni, Martin (advisor)
The thesis deals with attacks that cause faults in CPU and MCU calculations. A short voltage change in CPU or MCU is used to trigger the error. The theoretical part of the thesis deals with the description of how to cause and exploit these errors. This section also describes the most well-known protection against hardware attacks, which is a trusted execution environment (TEE). Inject a fault to TEE is the primary target of fault attacks. The practical part deals with the replication of PlunderVolt and VoltPillager attacks on Intel processors with an activated TEE SGX. Several experiments were performed to trigger faults in RSA and AES encryption within the SGX enclave. To obtain the encryption key from these errors, known analysis methods were used. The practical part also deals with the replication of the attack on ARM microcontrollers with an active TEE TrustZone-M.

PDA for Information Distribution in Closed Networks
Maslaňák, Martin ; Smrčka, Aleš (referee) ; Hanáček, Petr (advisor)
This thesis deals with creating client - server application. Client part of the application is created with a help of the Compact .NET framework and it is running on the mobile facility (PDA). Server part is written on .NET framework and it is running on the desktop computer. In the first part I characterize PDA facility, it's using and also I discuss communication between SQL Servers and PDA facilities. Next part describes .NET platform and advantages, which this platform provides. Also I tried to show differences between client - server architectures, because of understanding in my working. The last part of this work deals with implementation of the client - server application.

Frame Generator Based on 802.11 Standard
Švanda, Pavel ; Hanáček, Petr (referee) ; Kačic, Matej (advisor)
This thesis describes the design and implementation of the generator frames used for information transfer in wireless networks. At the beginning of the thesis there is described the introduction to the issue of data transmission in wireless networks 802.11 and the analysis of existing tools. Then it is designed language for describing the structure of their own frames and designed their own tools. The work also deals with the subsequent implementation of the resulting tool. Finally the results of the test are mentioned.

RTP Protocol for Real-Time Data Distribution
Škarecký, Tomáš ; Kočí, Radek (referee) ; Hanáček, Petr (advisor)
This paper explores the potential of process data distribution in real time using the RTP protocol. Firstly, there is an evaluation of existing protocols that are used for this purpose. Secondly, there is a description of the trio of protocols RTP, RTCP, and RTSP, explained their functions and explored possibilities for their expansion. On the basis of this acquired knowledge, problems which may occur with the distribution of process data by means of RTP are identified and their possible solutions are proposed. To demonstrate the data distribution via RTP, the application, that collects GPS position from the PDA and then provides clients with them, has been designed and implemented. Clients can display these data on the map.

USB Host with PIC Microcontrollers
Kučera, Pavel ; Janoušek, Vladimír (referee) ; Hanáček, Petr (advisor)
The aim of master thesis is implementation of USB host in a microcontroller PIC. The thesis contains description of ways of peripherals to computer connections with detailed description of USB bus. There are also discussed several approaches in implementations USB host for embedded systems. A concept of layered USB host system is designed on the basis of analysis of the state of the art. Finally, the designed system is implemented in microcontroller. Resulting firmware of development kit is tested on real USB device.

AeroWorks - Navigation Simulator (VOR & NDB)
Kubeňák, Róbert ; Hanáček, Petr (referee) ; Chudý, Peter (advisor)
This thesis deals with the issues of air navigation, specifically the radio navigation. The application simulates the activity of a radio indicator VOR and NDB. Simple application should help new pilots with the explanation how the radio navigation works, to help them understand the different states of the indicator, and last but not least to instruct how following these beacons will help to navigate the aircraft.

Wireless Communication for Home Automation
Sezima, Václav ; Janoušek, Vladimír (referee) ; Hanáček, Petr (advisor)
This bachelor's thesis deals with the issue of wireless communication among devices and sensors for home automation. The goal is to design and implement a device known as the gateway that is passing messages and commands between sensors and controller that controls them from central point, e.g. computer or mobile phone. A part of this thesis is also a creation of several sensors for the purpose of testing and demonstration. The gateway and sensors are based on development boards WEMOS and Arduino and supports multiple wireless technologies for communication with among themselves and controller.
