Sharing Part of the Screen
Bieliňski, Tomasz ; Sopuch, Zbyněk (referee) ; Zachariáš, Michal (advisor)
This paper deals with the analysis of the existing solutions, conceptual design and implementation of the application that will be able to transfer image to another computer screen at any time. It is divided into two parts: server and client. It uses a method of UDP hole punching.

Secure peer-to-peer communication system
Eliáš, Luboš ; Koutný, Martin (referee) ; Cvrk, Lubomír (advisor)
The main aim of this master's thesis is to implement a common, secure and peer-to-peer communication system. The system has ability to automatically establish and run a secure end-to-end connection. It has this ability even if a network address translator is in the way to the destination system, without need of any explicit configuration of this translator. The security procedures of this system are in a transparent manner masked from individual applications, which had to solve this challenge in their own way. A responsibility for a security is delegate to an application-independent subsystem working within the core of an operating system. The security of this subsystem is based on capturing the outbound and inbound IP packets and their authentication and encryption. The system was successfully implemented in MS Windows XP operating system, in programming language C++. Transfer rate of communication tunnel in different network bandwidth speeds was measured. Result shows, that in the case of use the system on standard PC sold nowadays is practically no decrease of the transfer rate in comparison to a common channel.

Network Synchronization of Data under OS Windows
Hellar, Jan ; Trchalík, Roman (referee) ; Očenášek, Pavel (advisor)
This thesis deals with an implementation of a tool for file synchronization over a network for OS Windows. It also illustrates what issues are associated with synchronization of files, such as collision detection and resolution and the issue of setting up connection between two devices over the internet when connected to the internet via NAT devices. Thesis presents factual implementation of collision resolver and application of methods for NAT traversal. By testing the final solution correctness of collision resolver and NAT traversal technique was verified. Results of testing are discussed and possible extensions are proposed.
