Just as well, Skype's solution is only arguably secure, it is based on RC4, and my well established opinion is that RC4 should have been retired at least 12 years ago, add in that the size of RSA keys they have chosen makes the security extremely suspect, all told it is at best a marginal design. > Any suggestions/help would be welcome. First suggestion would be to read the replies you received when you first posted this to sci.crypt. To quote Paul Rubin's response: IPSec supports udp natively, I thought. There is also a version of TLS for UDP. See: http://tools.ietf.org/html/rfc4347 That pretty much answers it directly. > The question is, HOW can we use IPSec to secure UDP data communication??? > (since using TCP to transport A / V data would cause huge latency > "delays".. > So SSL is also out of question...) It all depends on what you are trying to accomplish. There are many, many, many different purposes to encryption, combined with the many different concepts of how p2p should behave and the possibilities for what you are asking are effectively endless. > Also, I'm looking for suitable forums/IRC channels to discuss the topic > more. Could the people here suggest me some??? Your post to sci.crypt delivered a useful answer, you even replied to it.
