“…According to the works of [7], several VoIP protocols such as Session Initiation Protocol (SIP) [8], Inter-Asterisk eXchange (IAX) [9] and H.323 [10] still do not provide any form of security for the voice communication. Recently, some research works like in [11], [12], [13], and [14] have focused on peer-to-peer (P2P) in SIP instead the use of SIP servers to establish VoIP communications. A standard P2PSIP is currently being designed by the P2PSIP working group (WG) [11] in the Internet Engineering Task Force (IETF) to enable the discovery of resources that can be distributed in a SIP network and to eliminate or to reduce the need for a centralized server [12].…”

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...

“…There is no dependency between the peers, or such dependency is maintained at the lowest degree possible. This property makes the system more scalable and dynamic [19,20]. However, the major problem here is the lack of accurate data covering the system and the status of each member.…”

One of the important aspects of decision making and management in distributed systems is collecting accurate information about the available resources of the peers. The previously proposed approaches for collecting such information completely depend on the system's architecture. In the server-oriented architecture, servers assume the main role of collecting comprehensive information from the peers and the system. Next, based on the information about the features of the basic activities and the system, an exact description of the peers' status is produced. Accurate decisions are then made using this description. However, the amount of information gathered in this architecture is too large, and it requires massive processing. On the other hand, updating the information takes time, causing delays and undermining the validity of the information. In addition, due to the limitations imposed by the servers, such architecture is not scalable and dynamic enough. The peer-to-peer architecture was introduced to address these concerns. However, due to a lack of complete knowledge of the peers and the system, the decisions are made without a precise description of the peers' status and are only based on the hardware data collected from the peers. Such an abstract and general image of the peers is not adequate for the purpose of decision making. In this paper, a 4-dimensional model is presented for the purpose of information collection and the exact description of the peer's status, including the features of the peer, the basic activity, the time, and the specifications of the system. The proposed model is for a server-oriented architecture, but it also adapts to the peer-to-peer serverless architecture. Based on this model, a new approach is introduced for information collection and an exact description of the peers' status in a peer-to-peer system based on the Latin square concept. We evaluate the model in the server-oriented and serverless situations. The workload is considered as the basic activity in our evaluation. Our evaluation demonstrates that in a server-oriented situation, increasing the size of the system has a direct relation with time. However, a serverless situation does not follow this behavior. Correspondence: mirtaheri@iust.ac.ir 2. This model does not require a great deal of data to be gathered for defining the peer's status, the opposite of the situation that occurs in server-oriented systems.3. Due to the small amount of data collected by this distributed 4-dimensional model, less time is required to process it. In addition, less time is required to describe the peer's status.4. Since peers have the same role, there exists no communication overhead between the server and the member peers. Therefore, the peers' status will be described with higher precision in comparison to the server-oriented systems.

“…P2P-based computing allows for better utilization of the network resources by distributing the tasks among peers (nodes). This approach also increases the overall network resilience and fault tolerance by removing dependability on the servers' reliability and availability [1]. In P2P applications, nodes are connected with a logical overlay network and respond to queries or requests from other nodes to assign or request resources (data streaming, file sharing, .…”
