  • The Makeover from DVD to Blu-Ray Disc
    Praise for Blu-ray Disc Demystified “BD Demystified is an essential reference for designers and developers building with- in Blu-ray’s unique framework and provides them with the knowledge to deliver a compelling user experience with seamlessly integrated multimedia.” — Lee Evans, Ambient Digital Media, Inc., Marina del Rey, CA “Jim’s Demystified books are the definitive resource for anyone wishing to learn about optical media technologies.” — Bram Wessel, CTO and Co-Founder, Metabeam Corporation “As he did with such clarity for DVD, Jim Taylor (along with his team of experts) again lights the way for both professionals and consumers, pointing out the sights, warning us of the obstacles and giving us the lay of the land on our journey to a new high-definition disc format.” — Van Ling, Blu-ray/DVD Producer, Los Angeles, CA “Blu-ray Disc Demystified is an excellent reference for those at all levels of BD pro- duction. Everyone from novices to veterans will find useful information contained within. The authors have done a great job making difficult subjects like AACS encryption, BD-Java, and authoring for Blu-ray easy to understand.” — Jess Bowers, Director, Technical Services, 1K Studios, Burbank, CA “Like its red-laser predecessor, Blu-ray Disc Demystified will immediately take its rightful place as the definitive reference book on producing BD. No authoring house should undertake a Blu-ray project without this book on the author’s desk. If you are new to Blu-ray, this book will save you time, money, and heartache as it guides the DVD author through the new spec and production details of producing for Blu-ray.” — Denny Breitenfeld, CTO, NetBlender, Inc., Alexandria, VA “An all in one encyclopedia of all things BD.” — Robert Gekchyan, Lead Programmer/BD Technical Manager Technicolor Creative Services, Burbank, CA About the Authors Jim Taylor is chief technologist and general manager of the Advanced Technology Group at Sonic Solutions, the leading developer of BD, DVD, and CD creation software.

  • Broadcast Encryption for Differently Privileged
    Broadcast Encryption for Differently Privileged Hongxia Jin1 and Jeffery Lotspiech2 1 IBM Almaden Research Center San Jose, CA, 95120 [email protected] 2 Lotspiech.com, Henderson, Nevada [email protected] Abstract. Broadcast encryption is a primary technology that has been used for content protection. It enables a broadcaster to distribute content to a set of users so that only a privileged subset of users can access the content and another subset of revoked users cannot access the content. The main enabling block in a broadcast encryption scheme is the session key block, which each authorized user processes differently, but each gets the same valid session key. Currently all existing broad- cast encryption schemes have assumed that the content and authorized users are equally privileged. There are emerging scenarios that demand protection for con- tent with different privileges and for users with different privileges. In this paper we shall present a new broadcast encryption scheme that continues to employ single session key blocks but provides different privileged protections for differ- ent content and users. In particular we will expand the elegant subset-cover-based broadcast encryption scheme. We shall introduce a new concept called “security class” into the session key blocks. We use keys derived from a chain of one-way functions. Our approach is simple, efficient and secure. 1 Introduction This paper is concerned with protection of copyrighted digital content. Piracy is becom- ing a more and more serious concern in the movie and music industries, since digital copies are perfect copies. Broadcast encryption is an important cryptographic key man- agement approach, especially useful in content protection systems.
