1. A method, implemented in a server that includes one or more processors and a memory storing a registry database, of providing secure communication of a data string along a communication path including a plurality of devices, the method comprising:

  • adding to the registry database a first entity and a first identifier associated with the first entity;

    adding to the registry database a second entity and a second identifier associated with the second entity;

    providing to a first device of the plurality of devices, via a first secure communication channel, a first current value of the first identifier to enable a first encoding of the data string, wherein the first device is associated with the first entity, and wherein the first encoding of the data string encodes a plurality of bit sequences in the data string as a first plurality of encoded bit sequences;

    providing to a second device of the plurality of devices, via a second secure communication channel, a first current value of the second identifier to enable a second encoding of the data string, wherein the second device is associated with the second entity and downstream of the first device in the communication path, and wherein the second encoding of the data string encodes the first plurality of encoded bit sequences as a second plurality of encoded bit sequences; and

    providing to a third device of the plurality of devices, via a third secure communication channel, the first current value of the first identifier and the first current value of the second identifier to enable decoding of the data string, wherein the third device is downstream of the second device in the communication path.
