1. A method of controlling distribution of electronic information to a user device through a non-bidirectional communication protocol, comprising:

  • retrieving, at a user device, a segment of encrypted electronic information;

    first sending identification data from the user device to a gateway using the non-bidirectional communication protocol, the identification information including at least one of information associated with a user, information associated with the user device, or information associated with the segment of encrypted electronic information;

    first extracting at the gateway the identification data from said first sending;

    first forwarding the identification data from the gateway based on a bi-directional protocol;

    retrieving an encryption key for the segment;

    second forwarding a voucher to the gateway using the bi-directional protocol;

    second extracting the voucher from said forwarding;

    second sending the voucher to the user device using said a non-bidirectional communication protocol, the voucher including at least the encryption key associated with the segment; and

    decrypting, at the user device, the segment using the encryption key for the segment.
