Abstract

Voice over IP (IP: Internet Protocol) telephony is becoming more and more popular. Up to now, this technology is restricted to private users or closed corporate networks since there is no easy and secure way to authenticate a VoIP user against a provider using a public VoIP facility. So, a VoIP phone has to be configured manually to authenticate itself against a VoIP service provider. E.g. the following settings have to be provided to allow proper authentication and configuration: User specific settings: • User name • Password VoIP service provider specific settings: • SIP-Proxy (SIP: Session Initiation Protocol) • SIP-Domain • STUN-Server address (STUN: Simple Traversal of User Datagram Protocol) • DNS-Server address • SIP/RTP-Ports (RTP: Real Time Protocol) VoIP phone provider specific settings • NAT firewall IP (NAT: Network Address Translation) A new idea allows the use of public VoIP phones using Smart Card technology for secure and convenient authentication and configuration. The idea collects the user and VoIP service provider settings in a Smart Card controller. A master PIN (Personal Identification Number) to prevent misuse can protect the settings.

Smart Card based Voice over IP authentication and method therefor

Idea: Christian Schneckenburger, FR-Sophia Antipolis

Voice over IP (IP: Internet Protocol) telephony is becoming more and more popular. Up to now, this technology is restricted to private users or closed corporate networks since there is no easy and secure way to authenticate a VoIP user against a provider using a public VoIP facility. So, a VoIP phone has to be configured manually to authenticate itself against a VoIP service provider. E.g. the following settings have to be provided to allow proper authentication and configuration: User specific settings:

* User name
* Password VoIP service provider specific settings:

* SIP-Proxy (SIP: Session Initiation Protocol)
* SIP-Domain
* STUN-Server address (STUN: Simple Traversal of User Datagram Protocol)
* DNS-Server address
* SIP/RTP-Ports (RTP: Real Time Protocol) VoIP phone provider specific settings

* NAT firewall IP (NAT: Network Address Translation)

A new idea allows the use of public VoIP phones using Smart Card technology for secure and convenient authentication and configuration. The idea collects the user and VoIP service provider settings in a Smart Card controller. A master PIN (Personal Identification Number) to prevent misuse can protect the settings.

For easy and secure use, the user inserts his VoIP Smart Card in a public phone. This can be a public phone at airports or train stations etc. More likely is the use in hotel rooms providin...
