- 摘要：
- A method, comprising: receiving an encrypted segment of media data with an encrypted segment key over a unidirectional over-the-air (OTA) broadcast channel; providing an attestation request to an authenticator; receiving an attestation response from the authenticator based on an interaction with hardware to authenticate a user; decrypting, after receiving the attestation response, the encrypted segment of media data using a segment key to generate a decrypted segment of media data, wherein the segment key is based on the encrypted segment key.
