Abstract:
Embodiments of the invention provide a method and system for sending a session key file encryption key for use in the secure transmission of an encrypted media stream across a network. A logging node receives a double encrypted session key file encryption key. The session key file encryption key is used to encrypt session keys, which in turn can be used to decrypt the encrypted media stream. The logging node decrypts the session key file encryption key. Thereafter, the logging node sends the session key file encryption key to a reviewing node for use in secure transmission of the encrypted media stream.
