TL;DR: In this paper, a message may be passed from a first node to a second node via a communication link using a multi-stage cryptography algorithm distributed between the first node and the second node and applied by circuitry within the first and second nodes in which the multistage cryptography algorithm includes instructions for transmitting at least two optical signal transmissions across the communication path.

Abstract: Systems and methods for encoding a message are disclosed. A message may be passed from a first node to a second node via a communication link using a multi-stage cryptography algorithm distributed between the first node and the second node and applied by circuitry within the first node and the second node in which the multi-stage cryptography algorithm includes instructions for transmitting at least two optical signal transmissions across the communication path and using a number of independent transformations of polarization state of the optical signal transmission by a combination of the first node and the second node at least equal to the number of optical signal transmissions across the communication link.
