AUTOMATED TESTING OF 10GbE DEVICES
Avramović, Nikola ; Dvořák, Vojtěch (referee) ; Fujcik, Lukáš (advisor)
Tato práce se zabývá návrhem modelu pro funkční verifikaci a návrhem syntetizovatelného testru 10Gb Ethernet zařízení, které používají XGMII rozhraní. Pro popis modelu je použit programovací jazyk VHDL. Práce zahrnuje vytváření bus functional modelu a návrh testru, který se implementuje jako genericky self-test modul. Výsledný návrh umožňuje verifikaci a testování PHY a MAC vrstve. Pro implementaci testru byla použita vývojová deska DE5-Net osazena FPGA obvodem Stratix V GX od firmy Altera.

Attacks on Standard 802.11
Burian, Vojtěch ; Horváth, Tomáš (referee) ; Novotný, Bohumil (advisor)
Thesis is concerned about standard 802.11 especially wireless network security in historical and in current way. First part is focused on WEP secured wireless network problematics. Consequently, in different point of view we are focused on network security which was developed recently, for example WPA and WPA2 security. It will be marked the basic functioning and brief overview of standard 802.11, introduction to the known attacks on wireless network security and also indicate the main mistakes. Many older devices have only WEP security. Therefore, in this thesis is designed better and more coherent system of security of the WEP protocol. As well modern methods of security WPA and WPA2 are included. Second part is focused on the simulation of attack on security networks. In this part the problematic with beaking security WEP, WPA and WPA2 is discussed.

Evaluation of complex situations from airplane’s avionics
Vysloužil, Ondřej ; Svoboda,, Jiří (referee) ; Honzík, Petr (advisor)
Tento projekt se podrobně zaměřuje na data z avioniky a může být chápán jako horní vrstva nad systémy monitorujícími poruchy, která poskytuje dodatečné informace o letu. Pro konkrétní návrh byly vybrány Airbus A320 a A340 jako zástupci moderních a rozšířených dopravních letadel. Vyvíjená aplikace analyzuje dvě vybrané komplexní situace z toku dat palubní avioniky a hledá podmínky, které vedou k abnormálnímu chování letadla (nikoliv poruchám). Práce je primárně zaměřena na letové fáze, strukturu dat (a jejich kategorizaci) a na vývoj aplikace na bázi fuzzy systému s expertní znalostí uloženou v jeho pravidlech.

Wireless Network Security
Sedlák, Břetislav ; Krajsa, Ondřej (referee) ; Lambertová, Petra (advisor)
Master thesis focuses on wireless network security. The thesis is divided in two parts. First part describes today’s used standards and their components, topology and security methods as stealth SSID, MAC addresses filtration, WEP, WPA and WPA2. The last three methods are described in detail. In second part there are realized attacks on above described methods of security. There are described attacks on WEP as KoreK chopchop attack, fragment attack, attack FMS, KoreK and attack PTW. Then is described the dictionary attack on passphrase by WPA/WPA2 with PreShared Key authentication obtaining, precomputed hash tables for faster passphrase finding and for using more core procesors during dictionary browsing. The last attack describes obtaining of keystream used for encrypting of frames by WPATKIP and then sending custom data to client. It is described how to carry out each attack and how to protect against them.

Insurance frauds
Rácz, Pavel ; Ducháčková, Eva (advisor) ; Oborilová, Mária (referee)
The aim of my master thesis is to analyze the issue of insurance frauds. Theoretical part of the thesis familiarizes readers with the term insurance fraud, legislative in the Czech Republic, types of insurance frauds as well as with the ways to fight against insurance frauds. Practical part mainly covers the statistical and econometrical analysis of the size of detected insurance frauds in 2007-2014. Using econometrical analysis program Eviews is chosen the most suitable model for a time series and designed forecasts for years 2015 and 2016. The end of the thesis itself concludes economical interpretation of empirically measured and forecasted values.
