摘要：
Disclosed is, among other things, a method for distributing content items to authorized users. The method comprising: a content owner device (190), COD, obtaining a first content item (196a); the COD (190) obtaining a first tag associated with the first content item (196a); the COD (190) obtaining a first content key, CK1, for said first content item (196a); the COD (190) encrypting the first content item (196a) using CK1, thereby producing a first encrypted content item; the COD (190) using at least the first tag and a key derivation function, KDF, to derive a first derived key, DK1; the COD (190) encrypting CK1 using the DK1, thereby producing a first encrypted content key, ECK1; and the COD (190) transmitting information to a content server (108), the information comprising: the first encrypted content item and the first tag.
