Abstract
In a method for providing secure communication of a data string along a communication path, a first entity and first identifier, and a second entity and second identifier, are added to a registry database. A current value of the first identifier is provided to a first device to enable a first encoding of the data string, where the first encoding encodes a plurality of bit sequences in the data string as a first plurality of encoded bit sequences. A current value of the second identifier is provided to a second device downstream of the first device to enable a second encoding of the data string, where the second encoding encodes the first plurality of encoded bit sequences as a second plurality of encoded bit sequences. The current values of the first and second identifiers are provided to a third (e.g., destination) device to enable decoding of the data string.
