User Interface for WiFi Network Security System
Hirš, Petr ; Chudý, Robert (referee) ; Cvrček, Daniel (advisor)
This master thesis deals with analysis of an implementation of a reputation system. I particularly focus on analysis of user interface and to find an approach for possible user interface improvements of such a reputation system. I describe possible solutions and I also compare my solution with similar existing systems that are also focused on network security. A part of the diploma thesis is devoted to user interface design. There is also mentioned a database design together with a way the users log on into the system. A few chapters are devoted to the area of data presentation and the usage of template system. In the work there are also described interesting issues that appeared during the implementation. In the conclusion of this work, there is an overall project evaluation and also several remarks about the possible upgrade.

Analysis of wireless network attacks
Kačic, Matej ; Dočkal,, Jaroslav (referee) ; Zbořil, František (referee) ; Hanáček, Petr (advisor)
This work describes security mechanisms of wireless network based on 802.11 standard and security enhancement 802.11i of these networks known as WPA2, where the analysis of vulnerabilities and attacks on these networks were performed. The work discusses two major security issues. The first is unsecure management frames responsible for vulnerability with direct impact on availability and the other is the vulnerability that allows executing the impersonalize type of attacks. The system for generation attacks was designed to realize any attack very fast and efficient. The core of the thesis is the design of a system for attack analysis using the principle of trust and reputation computation. The conclusion of the work is devoted to experimenting with the proposed system, especially with the selection of suitable metrics for calculating the trust value.

Reputation systems - impact on customer's decisions
Štěpánek, Matěj ; Gála, Libor (advisor) ; Fortinová, Jana (referee)
This bachelor thesis is focused on the influence of reputation system to the customer decision. The main objective is to determine whether the reputation systems affect consumers. Objective was achieved using a survey among pre-selected group of respondents and evaluation of this survey. The result is a presentation of the results of the analysis of the impact of reputation on customer choice. Bachelor thesis is divided into two parts. In the first part I described and elaborated concepts important to the survey. Specifically these terms: Reputation, reputation systems, reputation sites, consumer behavior and purchase decision-making process. Furthermore, I characterized types of online consumers, which are also used in the survey. The second part presents the result of an analysis of data obtained from survey.

Web 2.0
Vítek, Pavel ; Rydzi, Daniel (advisor) ; Šindelář, Martin (referee)
The Bachelor's Thesis is concerned with Web 2.0 phenomenon. It defines meaning of this phenomenon and submits its features and characteristics : change in comunication system, freedom of content editing, content created mostly by its users, reputation systems, conversions of desktop applications to web services. It concentrates on technology background of web services, particularly AJAX, Adobe Flex, Silverlight. It focuses on designs, that were starting point for Web 2.0 and uses them to show principles of the whole concept. Selected designs examples were : community servers MySpace and Facebook, search engine Google with its additional services, video sharing server Youtube, bookmark server del.icio.us, content sharing server digg.com, the free encyclopedia Wikipedia, personalised internet radio and music encyclopedia last.fm. The work continues by describing current situation in the Czech Republic. In the end the paper summarizes and answers the basic questions asked in the introduction and mentions major obstacles of current development together with their possible solutions.
