Abstract
Systems and methods are provided for cyber security using light polarization. Data may be encoded in an optical signal. A seed may be converted to a target degree of polarization. The optical signal may be polarized to have the target degree of polarization and transmitted. The polarized optical signal may be received at a receiver and a degree of polarization of the received polarized optical signal measured. A seed may be converted by the receiver to an expected degree of polarization. The received polarized optical signal may be determined to be compromised based on a difference between the expected degree of polarization and the degree of polarization of the received polarized optical signal.
