Crushdepth Posted March 21, 2011 Share Posted March 21, 2011 Some security researchers have found a way to circumvent encryption of VOIP services that use variable bit rate compression (eg. Skype). They can use patterns in the compression associated with pronunciation to recognise spoken phrases, with 50% accuracy (up to 90% in some cases). Good podcast on it available at GRC (MP3, 40MB).

I wonder if this technique is applicable to STE phones? http://en.wikipedia.org/wiki/Secure_Terminal_Equipment Link to comment Share on other sites More sharing options...
