Why (Special Agent) Johnny (Still) Can't Encrypt

Here is a PDF version of the study, presented at the Usenix Security Conference, that details major security issues with the P25 digital protocol used by public safety agencies. It talks about encryption issues and how to mount a denial-of-service attack, capable of making encryption impossible (and forcing users to communicate “in the open”).

The report does a good job of explaining how P25 works and makes you wonder whether the huge investment in P25 post-9/11 actually bought us anything besides an illusion of protection.
