Security of real time multimedia data transmission
Otoupalík, Petr ; Koutný, Martin (referee) ; Hošek, Jiří (advisor)
This thesis deals with technology and security of real-time multimedia data transmission. The possibilities of the security of a multimedia data transfer and the mechanisms defined for the security of the signaling protocols SIP and H.323 are described with the view of security. The possible attacks on the real-time transfers are also mentioned. The basic requirements on the safe and reliable data transfer are specified. The main part of this thesis is focused on the security analysis of the data transmission of the selected communication clients, which use different security methods. The last part of the thesis deals with realization of simple attacks on multimedia data transmission and also on the SIP protocol.

Transmission of Audio Data Using RTP Protocol
Novotný, Roman ; Atassi, Hicham (referee) ; Kouřil, Jiří (advisor)
This project is about technology of multimedia transmission in the real time. Introduction of this work narrate model TCP/IP. Next the bachelor´s thesis is principally aimed on theoretical design of application, which is minimally able to transfer audio data between two computers by the help of the protocol RTP. This part is included in protocols for transmission of data in the real time, especially protocol RTP and then freely accessible libraries, which are written in language C and C++, in which is RTP protocol just implemented. End of this work comes out from these knowledges, in which is realized theoretical design and it is in developmental environment of Borland Builder C++.
