Attack Determination and its Security Analysis for Personal Communication in VoIP Networks
Voice over Internet Protocol (VoIP) is a technology that enables one to make and receive calls through the Internet instead of using the traditional analog PSTN (Public Switched Telephone Network) lines. Gtalk and Skype are frequently used for this purpose, which is a third party. So, the authors are utilizing their environment for conferencing. They are in need of a server to transfer the information from source to destination i.e. they are compromising user's privacy at a certain level as they do not provide full security to their audio packets. Here, they do propose, novel flow analysis attacks that ensures both privacy and demonstrates the vulnerabilities in peer-to-peer VoIP networks. Solutions are proposed by quantifiable k-anonymity metrics.
