Abstract: In one implementation, a media stream is recorded using one or more keys. The one or more keys are also encrypted. The one or more encrypted keys may be stored with the encrypted media session at a cloud storage service. A network device receives a request to record a media stream and accesses at least one stream key for the media stream. The stream key is for encrypting the media stream. The network device encrypts the stream key with a master key. The encrypted stream key is stored in association with the encrypted media stream.

Abstract translation: 在一个实现中，使用一个或多个键来记录媒体流。 一个或多个键也被加密。 一个或多个加密密钥可以与云存储服务处的加密的媒体会话一起存储。 网络设备接收记录媒体流的请求，并访问媒体流的至少一个流密钥。 流密钥用于加密媒体流。 网络设备用主密钥加密流密钥。 加密的流密钥与加密的媒体流相关联地存储。
