FYI: New Encryption System Would Protect Digital Music

heute in der New York Times:
Encryption for Digital Music

   Three mathematicians have a patent they say will make it
   impractical -- if not impossible -- to infringe copyrighted
   data like digital music.



The mathematicians, Jeffrey Hoffstein and Jill Pipher, both of Pawtucket,
R.I., and Joseph Silverman of Needham, Mass., patented a system they said
could quickly encode every second of a data stream with a different encryption
key. That means that a typical three-minute song could be scrambled into 180
different codes; anyone taking the time to break a single code would be
rewarded with only one second of music.
