Abstract: There is described a method of enabling a content receiver to access encrypted content, the content receiver forming part of a home network. The method comprises executing, on a device that also forms part of the home network, a key provisioning application. The method further comprises the key provisioning application receiving a key provisioning message and, based on the key provisioning message, providing to the content receiver via the home network one or more content decryption keys for decrypting the encrypted content. There is also described a device arranged to carry out this method. In addition, there is described a content receiver arranged to (a) receive from the aforementioned device, via a home network, one or more content decryption keys for accessing encrypted content; and (b) decrypt encrypted content using the one or more content decryption keys. Related computer programs and computer readable mediums are also described.
