Security and privacy have become critical in computer networks, especially with the emergence of E-commerce. Other than securing the transfer of data, users are interested in protecting their profile privacy against exposure attacks. Multimedia communications are at the core of new information and communication technologies. We seek to achieve end users' profile privacy without violating the Quality of Service constraints on the throughput, end-to-end delay, and jitter, as these parameters represent the critical factors in multimedia applications. We propose an end-to-end anonymity design that takes into consideration the constraints of Voice-over-IP applications in a hybrid network environment, which involves ad hoc and infrastructure networks. Using clusterheads for communication anonymity to preserve user profile privacy, as well as encryption of the real-time protocol payload, we prove using analysis and simulations that our model can be easily integrated into currently deployed network infrastructures.

A system of securing voice communication on mobile phone based on peer-to-peer SIP protocol (P2PSIP) is discussed in this paper. This paper presents a new key exchange protocol for secure Voice over Internet Protocol (VoIP) communication on mobile phones with P2PSIP. In this paper, security threats and issues in VoIP are analyzed. In our approach, we combine key exchange protocol based on the Elliptic Curve Diffie Hellman (ECDH) public key cryptography with identity based user's authentication, beside we use existent text message to exchange user information (identity, IP Address, and Port). The key exchange protocol is proposed to assure confidentiality and integrity of voice communication on mobile phone. We conducted security analysis between the proposed protocol with the existing ECDH protocol and compared their performance of key generating and key exchange time. The proposed method was validated by Scyther tool for proofing the proposed key exchange protocol. The experiment results showed that the combination of ECDH and authentication mechanism has proved to be secure against attacks. With the addition of the authentication scheme, total execution time of generate key and exchange key is slower by 11.70% than those of the original ECDH. Although the execution time run more slowly, we can guarantee that the VoIP communications still can be performed interactively without impairments because the key exchange process is carried out before communication between two peers begins. We conducted the confidentiality and integrity examination using Wireshark and Mean Opinion Score (MOS). Results of the Wireshark tool show that the VoIP communication is secure againts attacks. From the MOS measurements we obtained score 3.6 which means we achieve good quality and integrity of VoIP communication.Keywords: VoIP Security, P2PSIP, Key Exchange Protocol, ECDH, Scyther Tool IntroductionNowadays the information technology (IT) has been used as one of the most important things in human life. The rapid changes in today's information era have been faced by all organizations. It is shown that the entire organizations use the IT in all their activities, including the search of information and communication via internet technology. The internet is the largest system of connected computers around the world which people use to communicate with each other [1]. One of the methods used to communicate over internet technology is Voice over Internet Protocol (VoIP). VoIP is a method for transmitting voice as packets over the internet protocol [2]. Various reasons were put forward by organizations in the implementation of VoIP. One of the many reasons in the application of VoIP is cost savings including hardware requirements, training costs, the potential cost of electrical energy, and loss of business at a transitional stage [3]. Moreover, the adoption of VoIP can help reduce business costs through reducing operational cost, reducing maintenance costs, and reducing network infrastructure cost [4]. In other words, the key adv...
