Novel Secure Platform for Avionic Applications Based on Optical CDMA

We designed, built, and demonstrated a novel optical CDMA-based platform running at OC-24 data rate, with three users and one eavesdropper. Error-free operation with BER better than 10
^-12
was achieved. Based on our simulations, the testbed can support ten simultaneous users with BER<10
^-9
. Novel "dual-code" OCDMA transmitter and receiver were designed and demonstrated to deliver more secure data transmission approaching One-time Pad security by implementing optical layer XOR and having the capability to perform bit-to-bit code swapping. The testbed was developed under DARPA contract and delivered to Lockheed Martin for further performance evaluations in different avionic applications.
