This is usually the point where I stop reading. Of course 10 orders of magnitude is ~33 bits, so unless the A5 attacks crack a cipher with ~95 bits security, the estimate is grossly wrong. If (generously) A5 is 64 bits of work, AES is ~20 orders of magnitude stronger. -- /"\ ASCII RIBBON NOTICE: If received in error, \ / CAMPAIGN Victor Duchovni please destroy and notify X AGAINST IT Security, sender.
