We experimentally demonstrate security vulnerability in the temporal phase coding single-user DPSK- and CSK-OCDMA systems with a DPSK demodulator. In the systems without proper decoding, error free BER performance and clear open eye diagrams indicate the eavesdropping possibility for both systems. We also discuss the principle of DPSK demodulation attack. ©2010 IEEE.
