We propose a network implementation with enhanced security at the physical layer by means of time-hopping CDMA, supporting cryptographically secure point-to-point and point-to-multipoint communication. In particular, we analyze an active star topology optical network implementation capable of supporting 128 simultaneous users up to 20 km apart. The(More)
We propose a CDMA network implementation that enhances security at the physical layer. By using an active star topology supporting both point-to-point and point-to-multipoint communication, 128 ONUs can transmit simultaneously at rates of at least 12 Mbps, with a reach of 20 km, thus addressing access network applications. Numerical simulations demonstrate(More)
