As Voice-over-IP (VoIP) technology developed, VoIP services alternate the traditional PSTN gradually with their advantage of low rates. Instead of using the public switched telephone network, VoIP services exchange voice information over Internet. As the result, VoIP services have to suffer from the weaknesses of the IP network infrastructure and VoIP devices are easier to be attacked than traditional phones.
In our research, we analyze authentication mechanisms of Session Initiation Protocol, and address the weakness of current authentication mechanisms and the security threats to SIP. We use limited resources to implement an authentication mechanism in our embedded SIP user agent. The results of the Invite/Bye attack experiments confirm that our authentication mechanism in Direct Call and Proxy Call can both avoid malicious Invite/Bye attack.
