Acceleration of Ultrasound Neurostimulation Using High-Level GPGPU Libraries
Mička, Richard ; Kadlubiak, Kristián (referee) ; Jaroš, Jiří (advisor)
This thesis explores potential use of GPGPU libraries to accelerate k-Wave toolkit's acoustic wave propagation simulation. Firstly, the thesis researches and assesses available high level GPGPU libraries. Afterwards, an insight into k-Wave toolkit's current state of simulation acceleration is provided. Based on that, an approach to enhance currently available code for processors into a heterogeneous application, that is capable of being run on graphics card, is proposed. The outcome of this thesis is an application that can utilize graphics card. If graphics card is unavailable, a fallback into thread and SIMD based acceleration for processor is executed. The product of this thesis is then evaluated based on its performance, maintenance difficulty and usability.

Automatic Detection of Cryptography Used in Code
Mička, Richard ; Šilhavý, Pavel (referee) ; Hajný, Jan (advisor)
This thesis covers the topic of automatic detection of cryptography used in application code, which currently requires a lot of manual effort to analyze for a given unknown program sample. In this thesis, a possibility of implementing an automated tool for analysing the usage of Microsoft CryptoAPI cryptographic library by analysed programs is researched. This library is distributed with Microsoft Windows and can be misused by an attacker to cause significant harm to a victim. By recognizing cryptographic operations used and by presenting the summary of their use, it is in certain situations possible to distinguish malicious programs just based on the presented analysis summary. Main objective of this thesis was creation of such automatic analyser module integrated into Cuckoo sandbox. Along with the design proposal of such analyser, this thesis includes CryptoAPI library and Cuckoo sandbox functionality exploration and description. Proposed automatic analyser was successfully created, deployed and tested in production environment and the achieved results were discussed.
