Abstract
One embodiment provides a device that includes one or more line of sight transmitters configured to transmit signals over a line of sight communications medium, one or more transmitters configured to transmit signals over another communications medium and a controller. The controller is configured to perform an operation that includes retrieving a key adapted for use in decrypting encrypted content. The operation further includes transmitting the key to a second device over the line of sight communications medium using the one or more line of sight transmitters. Additionally, the operation includes encrypting data such that the data can be decrypted using the retrieved key. The operation also includes transmitting the encrypted data to the second device over the other communications medium using the one or more transmitters, where the second device is configured to decrypt the encrypted data using the key received over the line of sight communications medium.
