Abstract

A method for producing fingerprinted descrambling keys is described, the method including providing a conditional access module, providing to the conditional access module a content descrambling key and personalization data, the personalization data including data associated with the conditional access module, combining the content descrambling key and the personalization data, encrypting the combined content descrambling key and personalization data according to a key, and outputting the encrypted combined content descrambling key and personalization data. Related methods and apparatus are also described.
