A novel optical code-division multiple access (OCDMA) transmission system with all-optical exclusive or (XOR) encryption architecture is proposed and demonstrated. This all-optical system conducts OCDMA code swapping based on XOR operation. This multilayer approach eliminates radio-frequency data radiation and improves the confidentiality of the transmission system.
We propose and demonstrate the enhancement of data networks security using optical signal processing. Optical steganography that based on spread spectrum is used to inhibit the observation and analysis of data traffic. With the use of optical CDMA, service interruption is prevented in the presence of infrastructure attacks. Unlike conventional wavelength and time multiplexing approaches, the soft...
We propose and demonstrate the use of optical signal processing to enhance the security of data networks. Optical steganography is used to inhibit the observation and analysis of data traffic. With the use of optical CDMA, service interruption is prevented in the presence of infrastructure attacks. The soft blocking capability provides protection paths without the need of permanently reserving the...
