Abstract

Spam is a dominant problem on email systems today. One of the reasons is the lack of infrastructure for security and trust. As Voice over IP (VoIP) communication becomes increasingly popular, proliferation of spam calls is only a matter of time. As SIP identity scheme is practically similar to email, those share the same threats. We utilized Host Identity Protocol (HIP) to provide basic security, such as end-to-end encryption. To provide call filtering, however, other tools are needed. In this paper, we suggest applying trust paths familiar from the PGP web of trust to prevent unwanted communication in P2PSIP communities.
