Development of Architecture for Secured Data Transmission in OCDMA System with Designed Modified Walsh Code

This paper illustrates the secured data transmission process of MWC for OCDMA system. To transmit the data with a higher degree of security through a optical network, some smart and reconfigurable security processes are being introduced over a SAC-OCDMA scheme. This security process is mainly developed to embarrass the eavesdroppers by hiding the actual code signature of the users. Dynamic Central Control (DCC) process is used here to reconfigure the signature key dynamically during the data transmission through optical channel. Threshold algorithm has been used to decode the original data.
