Security enhanced SPECTS O-CDMA with four-state encoded data modulation

We demonstrate a security enhancement mechanism based on four-state temporal optical coding which protects a SPECTS O-CDMA upstream link against eavesdropping including DPSK detection. The FPGA-based code-hopping implementation facilitates future encryption by optical codes.
