TITLE:   Broadcast Encryption and Traitor Tracing

ABSTRACT:
Broadcast encryption and traitor tracing are beautiful cryptographic
problems with a rich history.  Many constructions to date are
combinatorial in nature using cover-free set systems and tree-like data
structures. In this talk we will survey both problems and describe new
purely algebraic constructions that are far superior to the
combinatorial methods.

This is joint work with Craig Gentry, Amit Sahai, and Brent Waters.
