This paper presents a conditional access solution suitable for broadcast networks (e.g. Eureka‐147 DAB, XM Radio's SDARS, etc.). This solution, called CA‐PK (Conditional Access through Public Keys), can only be implemented in software, although it can utilize external crypto processors and allows a content provider to operate a conditional access system independently of third parties (i.e. DAB or GSM network operators). Furthermore, it integrates the consumer into the protection chain, creating a social environment that discourages illegal redistribution of access keys. Copyright © 2003 John Wiley & Sons, Ltd.
