Network applications in .NET Framework
Koch, Michal ; Morský, Ondřej (referee) ; Lattenberg, Ivo (advisor)
The thesis deals with the programming of network applications using .NET Framework. C# is a programming language. The thesis consists of four parts. The first part is devoted to web services, their characteristics, practical publications and web service client which is the the most common case of use of this service. The second part deals with client-client communication. As an example a simple messages sending is shown here on which are explained the principles how to create this type of application and what classes are available. The third part deals with the communication clientserver. An server application is created to connect multiple clients and send their requirements and server response them. The last part is devoted to encrypted communication. The model client-client is extended to asymmetric encryption. The thesis contains also tutorial videos which show a simple ASP.NET application development and its connection to the web service or ASP.NET application that supports HTTPS protocol and the necessary IIS configuration.

Android App for Security Monitoring of Communication
Klepáčková, Karolína ; Dobeš, Petr (referee) ; Herout, Adam (advisor)
This diploma thesis is focused on implementation of application for security monitoring of network communication of other applications in mobile device with Android platform. Provides users information about security risks that may harm his/her privacy or device. It uses a local VPN to tunnel all data sent to the wireless network. These can be linked to an application that has sent them because the Android kernel is derived from the Linux kernel and can be used to retrieve information about established network connections and the application identifier associated with the connection. This mapping allows to get more information about an app that is potentially dangerous for your mobile device.
