Abstract
Systems and methods for managing a content encryption key and a seed to generate the content encryption key are provided. In one example, a method may include receiving a request for a content encryption key at a content encryption key service. The request includes a requesting entity fingerprint that corresponds to a requesting entity and a seed identifier that corresponds to a seed. The seed identifier is mapped to the seed and the requesting entity fingerprint mapped to a corresponding seed permission. If the seed permission entitles the requesting entity to receive the content encryption key, the key is derived using the seed and provided to the requesting entity.
