Performance Comparison on O-CDMA using M-Code Keying Technique to Enhance Optical Security

In this paper, an analysis of performance comparison on Optical Security deals with encryption technique for enhancing physical layer confidentiality in Optical Code Division Multiple Access (O-CDMA). O-CDMA systems and networks can be implemented at various data-rates and quality-of-service requirements against eavesdropping. Optical codes implemented with tree structures having multiple subsets of code words has been a recent area of research. Therefore confidentiality improvements by means of multicode-keying encryption like two code keying, four code keying and rapid codeword switching for different data rates are to be studied using the associated optical components (i.e., designed and validated) in OptiSystem simulation software.
