Approach to Identity Card-Based Voice-over-IP Authentication

Voice-over-IP (VoIP)-based services are becoming a popular alternative to traditional public switched telephony. The increasing number of users make VoIP also an interesting target for attackers. VoIP phishing and identity theft are gaining relevance. The lack of options for the reliable authentication between communication partners and the possibilities for anonymisation in IP-based telephony will allow attackers to steal confidential and personal information unperceived. This paper presents an approach for a reliable VoIP authentication, using federal electronic identity cards. The proposed authentication mechanism allows determining the identity of caller and caller in VoIP calls.
