[VOIPSEC] Help: Using SRTP for university project

[M Rizal B Azmi]

Hi all,

Thanks for the many responses. Cesc, I have visited and downloaded the miniSIP lib files from the website. However, I didn't find any instructions for compiling and running the application under win XP. Can I simply use an emulator like cygwin? 

Thanks & regards,
Rizal

miniSIP (www.minisip.org, see instructions for SVN repository) does SRTP with MIKEY key 
exchange for a long time now. The mikey works very well
between minisips, and some testing has been done with libSRTP with no major problems.
And since a couple months ago it also runs on windows XP/2000 boxes and a windows mobile 2003 
port is almost ready.

Regards,

Cesc

Hi all,
  
  I'm doing a university project on VoIP security. It's purpose is to  analyze the impact of basic VoIP security measures on performance.  Currently the scope is focusing on SRTP as it doesn't effect QoS. The  only software phone I know which supports SRTP is the the Snom 360  Softphone. However, I can't seem to make it dial or receive any VoIP  calls. Snom support hasn't replied as of now.
  
  My only other option is to use libSRTP but I do not understand how to  utilize it as my programming knowledge is very low. So far I managed to  compile it using cygwin but am stuck as to what to do next. After  applying SRTP, I would analyze the traffic using Ethereal and attempt  some packet sniffing to prove its functionality. The experimentation is  done at my uni lab with the following setup:
  
  - Analog Telephones (Generic � 2 units)
  - Analog Voice Modules (Cisco NM-2V � 2 units installed in routers)
  - Routers (Cisco 3725 Multiservice Access Router � 2 units)
  - Switches (Intel Express 410T & Cisco 3550 Catalyst � 2 units)
  - Desktop PCs (Compaq Evo D510 � Multiple units)
  - Switches (Intel Express 410T & Cisco 3550 Catalyst � 2 units)
  
  The two routers are interconnected via serial cable. Others are  connected using basic Ethernet UTP cables. Its a very basic setup of  two connected networks. (Not sure how to post the connection diagram in  here)
  
  Thanks in advance for your assistance.
  
  Regards,
