Digital Identity based VoIP Authentication Mechanism

Abstract

Confidentiality of Voice-over-IP (VoIP) based telecommunication has been an important topic in the past and gained relevance in the recent months. However, especially in private environments, secure communication has not been established yet. In this paper we introduce a new approach to secure private and business telecommunication using available digital identities, eg. social network identities. First, we focus on the confidentiality and integrity of the media data and second on the authenticity of the caller's identity. The objective is to prevent attackers to successfully eavesdrop VoIP-based phone calls.
