Abstract
In this paper new security and control protocol for Voice over Protocol (VoIP)
service is presented. It is the alternative for the IETF’s ( Engineering Task Force)
RTCP (Real-Time Control Protocol) for real-time application’s traffic. Additionally this
solution offers authentication and integrity, it is capable of exchanging and verifying QoS and
security parameters. It is based on digital watermarking and steganography that is why it does
not consume additional bandwidth and the data transmitted is inseparably bound to the voice
content.
Keywords: IP Telephony / VoIP security, digital watermarking, steganography
1. Introduction
Nowadays two the most important fields in which Voice over Protocol (VoIP) is
lacking are providing certain Quality of Service (QoS) parameters and security considerations
[3]. In this paper we consider new protocol that covers both those fields simultaneously. It
provides informatio
