Abstract
This chapter focuses on several imminent security applications in optical CDMA networks where the strong potentials of optical signal processing could be leveraged. As one of the dominant technologies in wireless communications, the unique features of CDMA have attracted wide attention in many optical network-ing areas. We explored the security properties of optical CDMA networks enhanced by the aid of optical signal processing. In particular, optical encryption can be incorporated into the network through optical XOR gating. Steganography, another form of information hiding, can also be achieved through temporal pulse spreading. For a coherent spectral phase-coded OCDMA network, share code scrambling is proven to be an effective and reliable way of achieving channel confidentiality. The chapter also presents a cost-effective and robust device technology. Its small footprint and multi-code processing capability could significantly simplify the node and system architecture.
