Abstract

In this paper, work to intensify the security of a forward compatible integrated asynchronous GPON/XGPON is presented by incorporating pseudo user scheme (PUS). Both the PON standards can work on same optical distribution network and security is beefed up from optical line terminal and optical network units without any tampering with the transmission line. Comparison of GPON/XGPON system has been done with and without PUS scheme and probability of correct bit detection is analyzed, both for authenticate receiver and eavesdropper. The performance of spectral amplitude codes such as Diagonal Double Weight (DDW) codes, Multi-Diagonal (MD) codes is studied as pseudo user. Further, their reliability to hide the authentic information under virtual user is observed. It is evident that system with PUS provides high security and out of DDW, MD codes, cross-correlation based DDW codes are less correctly detectable at eavesdropper receiver.
