Researchers crack APCO P25 public safety encryption, find DoS flaws

http://j.mp/n0WXG7  (Slashdot)

     "Two Australian security researchers, Stephen Glass and Matt Robert,
      have published a paper that details flaws in the encryption
      implementation (PDF) in the APCO Project 25 digital radio standard,
      used by emergency services and police departments world-wide. The
      paper details flaws in the DES-OFB and ADP encryption that enable the
      encryption key to be recovered by traditional brute force key
      searching. Also detailed is a DoS attack that makes use of
      unauthenticated radio inhibit mechanism."
