A fundamental requirement for commercial DAB data services is the availability of an easy to deploy conditional access (CA) mechanism for providing controlled access to services. Over the course of 2001 the WorldDAB Forum [Slashdot.org Website] has defined a set of requirements for conditional access for DAB data and audio services [WorldDAB Website]. To quote from the recent Call for Contributions for a DAB CA Mechanism"[t]he main points are minimal hardware requirements, support for DAB-only as well as DAB-mobile receiver platforms, [and] ease of deployment"[WoldDAB Forum]. Responding to this WorldDAB Call for Contribution we propose a DAB CA mechanism that implements these requirements.
