1. A network of computers with error correction code configured to transmit a key secretly and securely between a source node and a receiver node which do not a priori share a key, so as to establish a shared key between the source node and the receiver node, the network of computers comprising:
a first computer-based workstation operating as the source node and configured to encode the key into a plurality of distinct encoded source files, encoding being operatively implemented in one of: a) hardware, b) software, or c) a combination of hardware and software; a plurality of computer-based workstations operating as a plurality of intermediate nodes and configured to each receive a distinct encoded source file of the plurality of distinct encoded source files and transmit, to the receiver node, the distinct encoded source file when requested by the receiver; and a second computer-based workstation operating as the receiver node and configured to decode the plurality of distinct encoded source files and retrieve the key to establish the shared key, decoding being operatively implemented in one of: a) hardware, b) software, or c) a combination of hardware and software; wherein the encoding of the key comprises the following steps:
generating the key to be transmitted from the source node to the receiver node,generating one or more random packets independently and uniformly within the source node, andgenerating a distinct encoded file of the plurality of distinct encoded files for each intermediate node in the network, the distinct encoded file comprising a linear combination of the key, the one or more random packets that were independently and uniformly generated and corresponding error detection information. |
