Abstract
Systems and methods for managing group encryption are described. In certain methods, a content asset may be encrypted with an asset key. An account key may be determined. Using the account key, an encrypted content asset package may be generated. The asset key may make up at least a portion of the encrypted content asset package. The encrypted content asset package is decryptable with the account key. The encrypted content asset package and an identifier associated with the account key may be transmitted, for example to a playback device.
