[jdev] about GSOC idea on psi( Jingle RTP Encryption)
Hello, everyone I have looked up the GSOC project idea list, and have interest in several project ideas about security. The one that I am most interested in is about Psi---Jingle RTP Encryption. My name is Yu Xue, and I am a graduate student whose major is information security and cryptography. When in university, my major is computer science and technology. I am familiar with C,C++,Python and C#. The project that I prefer to is security-related. Currently my understanding about this project is just to implement in SRTP in Psi, either in avcall module or in a lower module according to the relationship that SPTP needs with the RTP session.Could some developers please give me some detailed or instructions on how to better understand and prepare this project or suggestions on writing proposal.Thank you! ps:Gajim's Jingle File Transfer interests me too.

I am glad to hear you are interested in those areas - we have plenty of projects that you could definitely help with :) Currently my understanding about this project is just to implement in SRTP in Psi, either in avcall module or in a lower module according to the relationship that SPTP needs with the RTP session.Could some developers please give me some detailed or instructions on how to better understand and prepare this project or suggestions on writing proposal.Thank you! ps:Gajim's Jingle File Transfer interests me too. If the Psi or Gajim devs do not answer you today I will poke them :) Have you gotten onto the jdev MUC ? That is also a great place to ask in realtime questions about Psi and Gajim. -- Bear b...@xmpp.org (email) bea...@gmail.com (xmpp, email) b...@code-bear.com (xmpp, email) http://code-bear.com/bearlog (weblog) PGP Fingerprint = 9996 719F 973D B11B E111 D770 9331 E822 40B3 CD29 ___ JDev mailing list Forum: http://www.jabberforum.org/forumdisplay.php?f=20 Info: http://mail.jabber.org/mailman/listinfo/jdev Unsubscribe: jdev-unsubscr...@jabber.org ___

Hi, Here s Gajim's point of view: It seems a student is interested in implementing Jingle FileTransfer in Gajim, and he also seems very interested in implementing encrypted Jingle session. So that would be excellent to be able to test between Gajim and Psi! Now We don't currently know what applications will really be posted, which one will be accepted, but that could be a nice thing to develop that on both clients. -- Yann ___ JDev mailing list Forum: http://www.jabberforum.org/forumdisplay.php?f=20 Info: http://mail.jabber.org/mailman/listinfo/jdev Unsubscribe: jdev-unsubscr...@jabber.org ___

Psi's Jingle voice calling support spans three modules: psimedia: Small wrapper to the GStreamer library. It handles multimedia device access and device selection, codecs, and RTP processing. It does not directly access the network. It is the application's responsibility to obtain RTP packets from the network and feed them to psimedia. Likewise, RTP packets produced by psimedia must be sent over the network by the application. iris: This library provides XMPP and ICE functionality. avcall: This is part of Psi itself and contains two subparts: jinglertp: Implements XEP-0166 (Jingle), XEP-0167 (Jingle RTP), and XEP-0176 (Jingle ICE-UDP) all at once. It uses the XMPP and ICE facilities of iris. Long term we'll want to break this code up so that we can support more Jingle things than just voice calls, like file transfer. But, for now, this all-in-one blob is what we have, and it offers a simple API: connect to a JID, and you are given an abstract packet pipe that you can read/write RTP packets with. main avcall code: bridges the jinglertp and psimedia parts together and offers a user interface. Also of note is the qca library, which we use for our security needs and contains most of the common cryptographic primitives. Probably SRTP can be implemented using qca functions. Where SRTP fits into this stack depends on what kind of knowledge it needs about the RTP session state. So you must first read the SRTP specification and fully understand its requirements. Further, make sure you know how SRTP may be used with sessions involving more than 2 participants (group multimedia conferencing), since that's an area we'd like to explore someday. If it turns out that SRTP can process arbitrary RTP packets, then probably it can be kept out of the psimedia layer. SRTP encryption could be applied to packets after they come out of psimedia, and incoming packets from the network could be SRTP decrypted before being fed into psimedia. Let me know if you have further questions or need more explanation. -Justin ___ JDev mailing list Forum: http://www.jabberforum.org/forumdisplay.php?f=20 Info: http://mail.jabber.org/mailman/listinfo/jdev Unsubscribe: jdev-unsubscr...@jabber.org ___
