    Leveraging the packet switched network for making phone calls or VoIP has come a long way now. Today, it has already replaced conventional circuit switching based telephones from the large organizations and now moving to capture the non-commercial users.

    In this demo, we will focus on the traffic analysis based security analysis of SIP and RTP protocols which are one of the most popular protocols for VoIP.

    These protocols are already gaining new adopters on high rate and also replacing older protocols like H323.We will discuss VoIPShark open source VoIP Analysis Platform which will allow people to analyze live or stored VoIP traffic, easily decrypt encrypted SRTP stream, perform macro analysis, generate summary specific to VoIP traffic/nodes and export calls/SMS/DTMF in popular user friendly file formats.

    We will also be releasing VoIPShark collection of Wireshark plugins written in Lua under GPL.

    VoIPShark is plug-n-play, easy to modify/extend and platform independent in nature. We will also discuss the currently available open source tools for SRTP decryption, their shortcomings and how VoIPShark address those.

    利用分组交换网络进行电话呼叫或VoIP已经取得了很大的进展。如今,它已经取代了传统基于电路交换的电话 。从大型机构,至现在正着手吸引非商业用户都用它。在本演讲中,我们将重点放在基于流量分析的SIP协议和 RTP协议的安全性分析,这是目前最流行的VoIP协议之一。这些协议已经以很高的速率获得了新的采用者, 并取代了像H323这样的旧协议。我们将讨论VoIPShark开源VoIP的分析平台,它将允许人们分析 实时或存储的VoIP流量,轻松解密加密的SRTP流,执行宏分析,生成特定于VoIP流量/节点的摘要,并以流行的文件格式导出call /SMS/DTMF。
    我们还将发布VoIPShark Wireshark插件集合,这些插件是在GPL下用Lua编写的。
