First Claim
Patent Images
1. A method of transmitting data between a first location and a second location comprising:
- obtaining a first data stream at said first location;
packet encrypting said first data stream;
sending said packet encrypted first data stream to said second location;
obtaining a second data stream at said second location;
bulk encrypting said second data stream; and
sending said bulk encrypted second data stream to said first location.

Abstract
A method is provided for asymmetrically encrypting data communicated between a ground platform and multiple airborne platforms. The method includes packet encrypting ground-based data so as to preserve routing information while encrypting the remaining data. The packet-encrypted data is then transmitted to the airborne platforms. The method also includes bulk encrypting airborne-based data so as to maximize security. The bulk-encrypted data is then transmitted to the ground platform.

25. A communications network including a forward link and a return link, the network comprising:
-
a packet encryptor on said forward link for packet encrypting data sent thereover while preserving routing information contained in said data; and
a bulk encryptor on said return link for bulk encrypting data sent thereover to maximize security.
