IPclip: An Architecture to restore Trust-by-Wire in Packet-switched Networks

摘要

During the last decades, the Internet has steadily developed into a mass medium. The target group radically changed compared to, e.g., the 90s. Because virtually everyone has access to the Internet, threats due to insecurity and anonymity reach critical levels and have to be tackled by both carriers and Internet Service Providers. Regaining Trust-by-Wire, comparable to classic fixed line telephones, could mitigate or even solve problems like Spam, Phishing, and the localization of VoIP emergency calls. This paper presents the hardware implementation of a new and highly flexible solution - Internet Protocol-Calling Line Identification Presentation - which provides additional support for new services to restore people's confidence into the Internet. Supported services are VoIP emergency calls, Spam detection and prevention, and phishing prevention. Already in the access network, the hardware adds unambiguous location information on the packet's origin to IP packets. We document the hardware design of the solution. Furthermore, hardware consumption and performance of a prototype are presented.
