One thing I've never understood all along is how Iran managed to capture the drone intact. Was it guided into a runway landing somehow? Or else how did they not crash it?
Drone captured by Iran may mean military GPS RSA "red key" has been compromised

#12Why would you need to have keys at all? Just rebroadcast the signal with a different delay for each satellite.
The GPS military signal is protected by virtue of being CDMA-modulated by a long, pseudorandom sequence (the output of a keyed, secret PRNG). Because of the spread-spectrum nature of CDMA, it would be impractical to record the signal without having the key in the first place. And if you did have the key, why go through the trouble of recording and replaying the signal when you could directly spoof it?

#13The encrypted GPS service doesn't use RSA.
Yes it does, see slide 6:

#14The article confuses me: it seems to be conflating the RSA algorithm (which I could easily believe might be used to encrypt military GPS) with the RSA company (a division of EMC which was hacked and had its SecurID product compromised recently).
Am I missing something, or is the author just confused? Why would having "broken into EMC's RSA servers" be at all related to being "in pursuit of a cryptanalytic attack against RSA"?

Do you have a source for that?

#16Iran is not some backwater and it's not north korea. When politicians sing about "bomb Iran" these are the innocent people they are talking about killing http://www.youtube.com/watch?v=6v6kF8i-mbw http://www.theatlantic.com/infocus/2012/01/a-view-inside-ira... Before 1970 you would not be able to identify pictures of iran from parts of the usa http://www.pagef30.com/2009/04/iran-in-1970s-before-islamic-... Currently…
Do people earn their humanity by their proximity to Standard American Ideals? What about those who are very much unlike Americans? Do you they deserve to get nuked back to the $EPOCH?
Um...he was actually supporting your point.

Reading http://news.softpedia.com/news/Iranians-Capture-US-Drone-wit... it sounds more like the attack was on the drone itself which manifests itself if the drone loses GPS lock. Perhaps a secondary navigation system that can more easily be spoofed?
Also, this article in New Scientist http://www.newscientist.com/blogs/onepercent/2011/12/did-ira... says that the drone was damaged on landing, hence the drapes around the bottom of the aircraft in the picture.

The wings appeared to be held on by duct tape. Perhaps it didn't fall from very high.
