Title: Collusion Resistant Broadcast Encryption

Abstract: This is a presentation of the paper "Collusion
Resistant Broadcast Encryption with Short Ciphertexts and Private
Keys" by Dan Boneh and Craig Gentry.

Broadcast encryption has several applications including access control in
encrypted files systems, satellite TV subscription services, and DVD
content protection. The encryption scheme is said to be collusion resistant
even if all users outside of the set S of legitimate recipients collude,
they can obtain no information about the contents of the broadcast.

In this talk, we will present the first fully collusion resistant broadcast
encryption scheme with constant size ciphertexts and private keys for
arbitrary receiver sets.
