Abstract

Secure content transfer systems and methods to operate the same are disclosed. Disclosed example systems include a client device for use at a physical location and a media server for use at the physical location. The example media server includes a security device to determine a first encryption secret based on a first encryption key and to determine a second encryption secret based on a second encryption key. The media server also includes a decrypter to decrypt received encrypted content for requested content based on the first encryption secret and an encrypter to re-encrypt the decrypted content data for the requested content based on the second encryption secret. In addition, the media server includes an interface to send the re-encrypted content data to the client device, wherein the client device is to decrypt the re-encrypted content data based on the second encryption secret to access the requested content.
