Abstract
In this article, an M-code keying OCDMA system with parallel encoders/decoders is presented and its security performance is quantitatively analyzed. Under brute-force searching techniques, the formula about the average searching time is derived. The bit-correct-interception possibilities for tapping individual and multiple users’ signals are calculated, respectively. By analysis, it is shown that the security performance of an OCDMA system can be enhanced by employing M-code keying.
