<p>Broadcast encryption was designed to answer the question--Can two devices, previously unknown to each other, agree upon a key if they only have a one-way communication path? They can, and the one-way nature of this communication gives the technology its name. Recent advances in broadcast encryption threaten to unseat public key encryption?s use in certain applications. To commercialize the technology for media content protection, IBM, Intel, Matsushita, and Toshiba developed the Content Protection for Recordable Media technology. Devices that use CPRM have already been marketed, including digitalaudio players and video recorders, and some flash-memory music players. The authors? work focuses on various aspects of content protection, which they consider to be the ideal application for broadcast encryption.</p>
