Abstract

An enhancement of data networks security using a hybrid WDM and SAC/Optical CDMA System is proposed. Secure transmission for dedicated users is achieved by overlaying a covert channel onto a multichannel WDM network. The covert channel is spectrally encoded using spectral amplitude coding (SAC) with unipolar Modified Double Weight (MDW) as the signature address code. OCDMA improves service availability in the presence of physical infrastructure attacks. With the use of WDM channels, the difficulty for an eavesdropper to intercept and decode the secure signal is increased. A simulation is presented as a demonstration of the concept.
