Conditional Access.

Digital content and software needs to be protected from unauthorised distribution and/or access.

The research topics in the conditional access area focuses on encryption of data streams, determining who has access to paid content (such as different channels on DSTV), and watermarking audio and video content in order to determine the origin of a piece of pirated content.
