The bachelor's thesis is focused on the problematics of software emulation in the context of teaching the principles of computer architectures and associated hardware. There is a whole emulator development process presented in an example of a particular computer system, which is the Nintendo Entertainment System. The process consists of understanding the basic principles behind software emulation, analysis of the emulated system, design of the solution based on discovered information, and finally, the implementation of the emulator including testing. The goal of the implementation is to be as comprehensible as possible. The project also includes a universal platform for emulator development. To motivate other students (or hobbyists) interested in the topic, there is a list of possible extensions of the project in the last chapter of the thesis. Detailed documentation was created to make the project more accessible for emulator developers and potential project contributors.

The bachelor thesis focuses on working with the CEC1702 cryptoprocessor. The first part of the thesis is oriented on programming the cryptoprocessor, modification of existing implementation of the library for operating on large numbers, and implementation of the Paillier cryptosystem for the mentioned cryptoprocessor. The thesis also includes development of firmware that allows the use of the RSA-CRT encryption algorithm and the Paillier cryptosystem with variable key length. The second part of the thesis focuses on fault injection attacks on the RSA-CRT encryption algorithm. Power supply glitches and clock source glitches used are generated using the ChipWhisperer suite. The attacks are first successfully performed on the STM32F3 microcontroller, where RSA-CRT is implemented using the library for operating on large numbers from the first part of the thesis. Using the knowledge from the attacks on the STM32F3, a further set of attacks was designed for the CEC1702 cryptoprocessor, using only power supply glitches, as the CEC1702 does not have the ability to use an external clock source. The attack was performed on two versions of RSA-CRT. The first version corresponds to the implementation for the STM32F3. The second version uses a hardware accelerator for cryptographic operations. The attack was successful on both versions of the implementation. This thesis outlines a possible approach to extend the created implementations and the implemented fault injection attacks. Created manual for programming the cryptoprocessor and the firmware documentation can be found in the appendix of the thesis.

The aim of this thesis is to create control software for a custom-made embedded system using an STM32WB microcontroller unit that can be configured via Bluetooth Low Energy (BLE). The thesis concerns itself with analyzing the criteria placed on the software and the development of said software. The thesis also places emphasis on compatibility with the complementary BLE Android application that was developed for the custom device, but it does not cover the development of the application itself. The software is made from the ground up, because no suitable existing project was found that could be used as its basis. The result of the thesis is functional control software that can be used on the custom-made devices or as a basis for a similar project.

This thesis proposes a versatile hardware framework for elliptic curve cryptography. The framework supports modular arithmetics with up to 256-bit general modulus and optimized arithmetic for P-256, Ed25519, and Curve25519 curves, enabling easy implementation of various elliptic curve cryptography algorithms. Full elliptic curve and Edwards curve digital signature algorithms can be performed using this framework as well as the X25519 algorithm for Diffie-Hellman key exchange. Such a framework finds its application area in nowadays rapidly expanding field of hardware wallets or IoT devices. As the design is intended to be implemented in ASIC, it is designed to be area efficient. Individual hardware units are reused for several different calculations. The framework allows to implement several side-channel attack countermeasures, mainly masking techniques, even after the framework is designed.

This bachelor thesis deals with the design and implementation of a functional prototype of a smart mirror. The analytical part of this work is devoted to a detailed analysis of already completed projects, whether by technology enthusiasts or products available on the market. The possible benefits or negatives of the investigated solutions are evaluated in this analytical part of work, either from the point of view of the materials used, technologies or the way of user control. In the next phase of the analytical part, possible SW platforms and HW products are considered, which could be used for the implementation of a smart mirror. Great attention is paid especially to the selection of suitable display components - various types of glasses and displays are discussed here. The practical part of this work deals with the creation of a functional prototype of a smart mirror. The construction of the mirror is unique, frameless and is designed to offer the user the largest possible display area for information and at the same time a modern design with voice control. The created prototype is based on the Raspberry Pi platform, and also are listed here expandable modules for light control. The steps for installing the individual SW platforms HomeAsistant, MagicMirror^2 and the voice assistant Kalliope are described. Part of the work is also a procedure how to configure individual platforms, solve possible problems and also it is indicated the way of possible expansion or use of the designed mirror in a smart home. Finally, the prototype is thoroughly tested to ensure the functional reliability of the entire system.

This thesis focuses on securing block ciphers against side-channel attacks that can deduce the secret key from a device's power consumption. Multiple-and dummy-rounds countermeasure was tested because its effectiveness is yet to be proven. To verify previous results and find possible errors in countermeasure design, I created VHDL implementation of PRESENT cipher secured by dummy rounds. This version underwent a series of tests that revealed a leakage at the beginning of the cryptographic operation. Further improvements led to progressively better but still unsatisfying results. The most prominent feature was the insertion of a random number of dummy clock cycles before the first valid operation. I also examined the influence of added dummy registers used as storage for outputs of dummy rounds. Furthermore, as part of my effort, I developed tools useful for future testing of multiple- and dummy-rounds countermeasure.

This bachelor thesis looks into the development of a portable device for electrocardiography which can measure three elemental ECG leads, is battery powered and transmits measured data into a central data collection unit via WiFi. The patient is therefore able to move and the physician can see real time information about his/her condition. The core of the system is an ECG analog frontend -- ADAS1000 from Analog Devices. The data are processed by STM32L0 MCU and sent to the data collection unit using ESP8266 WiFi module. The main output of this thesis is a complete prototype design which contains both hardware and software. It is very simple to manufacture a PCB from the presented data and thanks to enclosed source codes of MCU firmware and central unit software (which can be run on any Linux PC) it is possible to quick start the usage of the prototype. The enclosed DVD contains prototype photos, PCB design and source codes.

We explored the possibilities of the Differential Power Analysis (DPA) on the Field Programmable Gate Array (FPGA). We have modified the application for measuring a power consumption, created scripts for performing DPA, and created different implementations of AES algorithm for FPGA. Developed scripts and applications for DPA were verified against AES implementation for smart cards. Once those applications successfully broke the implementation for smart cards, we continued with the application of DPA against AES implementation for an FPGA board. DPA against FPGA was performed in six different configurations. Those configurations differed in AES implementation for FPGA, in board configuration, in oscilloscope setup, and in method of the attack. We found variants that could be successfully broken. We found out that an oscilloscope and measuring environment setups has major impact on the feasibility of the DPA on FPGA. The implementation is less important for the success of the attack. The most important aspect of the implementation was the clock frequency. We have also found out that using different power sources and removing capacitors on the FPGA board have significant impact on the feasibility of the DPA.

Aim of this work is to compare influence of Fault-Tolerance techniques on differential power-analysis (DPA) resistance of AES cipher implemented in Altera FPGA. After attacking simple variant, I attacked fault-tolerant variants of the cipher and compared results with the simple variant. From the comparison follows that the use of informational redundancy at SubBytes operation, spatial and time redundancy at both round and algorithm level had minimal influence on resistance against DPA, as the number of power traces necessary to obtain the key had not changed significantly.
