Secured data transfer between client and server using hessian protocol
Hořejš, Jan ; Uher, Václav (referee) ; Burget, Radim (advisor)
The objective of this work was the choice and creating of a secure communication protocols between server and a client in order to transmit sensitive medical data through an unsecured network. The first part is focused on a theoretical description and the properties of both client and server applications, metaprotocols, their purpose and thein appropriate use. The second part describes creation of secure communication and creation of demonstration application for secure data transmission. It is demonstrated by setting the server, creation of client applications and compilation of the certificate, including its installation.

Anonymous communication on the internet
Hořejš, Jan ; Babnič, Patrik (referee) ; Rosenberg, Martin (advisor)
The objective of this master’s thesis was to describe current capabilities of anonymous browsing over the Internet. The theoretical part focuses on three main methods of anonymization with main focus on Tor network. The master‘s thesis describes advantages and disadvantages of different solutions and possible attacks on them. In the next part is demonstrated Tor network, implementation of Hidden service and secured access to the server for clients and possible attacks against this proposal. The work also includes the results of measurements of all three anonymizers and the effects on their speed.

Methodology of optimal usage of load balancing in data center environment
Nidl, Michal ; Gála, Libor (advisor) ; Hořejš, Jan (referee)
The following master thesis is focused on creation of methodology for optimal usage of load balancing in data center environment. Thesis is divided into eight chapters. The first chapter describes the reasons why to deal with this topic further. The second chapter summarizes the state of load balancing. This chapter is based on research of already elaborated thesis which were focused on load balancing in different ways. The third chapter summarizes load balancing including its key principles. The fourth chapter describes an actual state of load balancing in data center environment. An observation of real usage of load balancing in selected data center was used for the main purpose of this chapter. The fifth chapter consists of analysis of the currently existing methodologies which are used from the infrastructure projects purpose. The sixth chapter deals with creation of methodology for optimal usage of load balancing in data center. The seventh chapter evaluates usage of methodology by applying of this methodology to real practical example of implementation of load balancing. The eighth chapter summarizes all detected conclusions.
