System for transmitting encrypted data
First Claim
1. A data transmission system comprising:
- a plurality of nested communication links communicably connected to a network, each communication link including an originating node and a corresponding terminating node which are adapted to route a transmission therebetween, wherein the transmission between the originating node and the corresponding terminating node of an outermost communication link is routed through at least one inner communication link;
the outermost communication link is adapted to generate the transmission at the corresponding originating node, the transmission including a data part and a first header part, both in an encrypted format, route the transmission to the corresponding terminating node, and decrypt the data part and the first header part at the corresponding terminating node; and
the at least one inner communication link is adapted to modify the transmission at the corresponding originating node by removing unencrypted references to other communication links and adding a second header part in an encrypted format, route the transmission to the corresponding terminating node, and decrypt the second header part at the corresponding terminating node.

Abstract
A system for transmitting encrypted data. A plurality of nested communication links are communicably connected to a network. Each communication link includes an originating node and a terminating node which are adapted to route a transmission therebetween. Transmissions between the originating node and the corresponding terminating node of the outermost communication link is routed through at least one inner communication link. The originating node of the outermost communication link generates a transmission having a data part and a first header part, both in an encrypted format, and routes the transmission to the corresponding terminating node. The originating node of an inner communication link modifies the transmission by removing unencrypted references to other communication links; adding a second header part in an encrypted format, and routing the transmission to the corresponding terminating node, where the second header part is decrypted and the transmission is rerouted to an outer communication link.

7. A data transmission system comprising:
-
a first communication link communicably connected to a network and including a first originating node and a first terminating node, wherein the first originating node is adapted to generate a data transmission, the data transmission including a data part, a first header part, and a routing envelope, the data part and the first header part being in an encrypted format, and route the data transmission to the first terminating node, and the first terminating node is adapted to decrypt the data part and the first header part; and
a second communication link communicably connected to the network and embedded within the first communication link such that the data transmission routed from the first originating node to the first terminating node is routed through the second communication link, the second communication link including a second originating node and a second terminating node, wherein the second originating node is adapted to receive the data transmission, remove from the routing envelope references to the first communication link, add a second header part in an encrypted format, and reroute the data transmission to the second terminating node, and the second terminating node is adapted to decrypt the second header part and reroute the data transmission to a next node. - View Dependent Claims (8, 9, 10, 11, 12, 13, 14)
