A more generic tool...

Post #396,674 by Another Scott 11/29/14 9:35:36 AM Reply	A more generic tool... There's something called the "NRL Protocol Analyzer" that seems to have a lot of math behind it. A 12 page mini-tutorial PDF describing it, what it does, how it works, is here. (The PPT version is here.) It's from the mid-'90s. There are undoubtedly more powerful tools now, but sometimes it helps to take a step back. (This stuff is outside my area. I just thought I'd mention it in case you haven't seen it.) HTH a little. Good luck! Cheers, Scott.

Checking a few more things then start writing.

That brings me to the following quote: “The generation of random numbers is too important to be left to chance.”—Robert R. Coveyou There have been "pseudo-random number generators" that were very insecure. Alex "There is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge." -- Isaac Asimov

Post #396,718 by scoenye 11/30/14 8:06:17 PM Reply	It is mainly a key transport problem Any electronic transport method is vulnerable in one way or another. The security of the OTP is reduced to the level of the method used to transport the key. That is why there still is no viable electronic OTP. Even the method I posted earlier still requires a secure physical meeting between each pair of messengers.
