Abstract

A broadcast encryption (BE) system allows a center to send encrypted messages over a public broadcast channel towards many users. The use of BE has been proposed for different scenarios: multimedia broadcasting, encrypted file systems, secure mailing lists and peer-to-peer applications.BE protects the communication channel, but not the platforms where the contents are created, distributed or received; in this early work we outline a system where the protection of the communication channel offered by the BE is extended to the platforms using trusted computing (TC) techniques. We call such coupling of TC and BE trusted broadcast encryption (TBE).
