Theoretical Analysis and Experimental Investigation on the Confidentiality of 2-D Incoherent Optical CDMA System

Confidentiality performance is analyzed in detail for a 2-D incoherent optical code-division multiple access (OCDMA) system, especially a multi-user two-code-keying wavelength- hopping time-spreading (WHTS) code system. The WHTS system's robustness against brute-force attacks is discussed. Other than brute-force attacks, several practical approaches are proposed to compromise the WHTS system. The effectiveness of these practical approaches is theoretically analyzed and an experimental demonstration is provided. Possible approaches to improve WHTS system's confidentiality are proposed and discussed.
