Encrypted audio streaming
The disclosed technology relates to broadcasting encrypted data to multiple receiver devices, where some receiver devices have long-term access to the encrypted data and some receiver devices have a temporary access to the encrypted data. Receivers having long-term access are part of a “member group” because these member group devices have a master key and the master key enables the member group devices to derive the necessary information to decrypt the encrypted broadcast. In contrast, devices with temporary access possess only a guest key and not master key, without a master key the devices need to receive the guest key from another device to decrypt the broadcast. Access to the encrypted stream can also be based on broadcasting multiple or single diversifiers, where a diversifier can include group identification information to assist in restricting access to the encrypted stream. |
