Information security architecture for remote access control using non-bidirectional protocols
First Claim
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;
sending identification data from the user device 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;
retrieving an encryption key for the segment;
forwarding a 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.

Abstract
A system and method of controlling distribution of electronic information to a device through a non-bidirectional protocol is disclosed. At a user device, a segment of encrypted electronic information is retrieved. Identification data is sent from the user device using the non-bidirectional communications protocol, where the identification information includes 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. A copy of an encryption key for the segment is retrieved. A voucher is forwarded to the user device using the non-bidirectional communications protocol, the voucher including at least the encryption key associated with the segment. At the user device, the segment is decrypted using the encryption key for the segment.

12. A system for controlling distribution of electronic information to a user device through a non-bidirectional communications protocol, comprising:
-
said user device being configured to access a segment of encrypted electronic information and to send identification data to a remote site using the non-bidirectional communications 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;
a remote site including at least one server configured to retrieving a copy of an encryption key for the segment and forward a voucher to the user device using the non-bidirectional communications protocol, wherein the voucher includes at least the encryption key associated with the segment; and
said user device being configured to receive said voucher and decrypt the segment using the encryption key for the segment. - View Dependent Claims (13, 14, 15, 16, 17, 24)
