Various embodiments of a system and method for decentralized management of keys and policies are described. Various embodiments may include a computer system configured to receive a request from a remote computer system associated with a recipient of content. Such request may include an encrypted content encryption key that is encrypted with a packaging key utilized by a packaging entity. The request may also include an identifier identifying the packaging entity. In some embodiments, the request may also include policy information specifying one or more usage rights of the content. The computer system may be configured to, in response to determining the recipient is authorized to access the content, generate the packaging key based on the identifier and a secret root seed, utilize the generated packaging key to decrypt the encrypted content encryption key, and provide the decrypted content encryption key to the remote computer system. |
