Abstract

A method of an existing media device for distributing a media key to a new media device joining a local area network or revoking an existing media key. For distributing a media key, a set of key generation counter ('KGC') values are received from the media devices (1010). Each value is then voted on based on the network keys utilized by the existing media device (1012). Next, all votes for each value are gathered from the media devices (1012). A popular values is determined from the set of values (1014). To revoke a media key, a NONCE is encrypted with the network key (1104). The encrypted NONCE is then distributed to media devices of the local area network (1108). Next, votes are gathered from the media devices of the local area network (1110). All votes are received from media devices that are able to decrypt the NONCE using the media key.
