摘要
A key selection vector for a revocation list in an HDCP system as well as a mobile device and a method for processing a key selection vector, a digital content output device using a key selection vector and a revocation list for use in an HDCP system comprising a key selection vector are described. It is desired to improve handling of key selection vectors of revocation lists. A structured key selection vector for a revocation list is provided. The key selection vector is structured to contain at least one bit field with a predetermined number of bits and at a predetermined location in the key selection vector. The bit field contains information relating to a group property of a device, which group property allows to process as a group a plurality of key selection vectors storing the same or similar group property information in said at least one bit field.
