Secure communication in fiber optic systems via transmission of broad-band optical noise.

چکیده
We propose a new scheme for data encryption in the physical layer. Our scheme is based on the distribution of a broadband optical noise-like signal between Alice and Bob. The broadband signal is used for the establishment of a secret key that can be used for the secure transmission of information by using the one-time-pad method. We characterize the proposed scheme and study its applicability to the existing fiber-optics communications infrastructure.

متن کاملModulation Formats for High-Speed, Long-Haul Fiber Optic Communication Systems
1. Introduction The goal of an optical fiber communication system is to transmit the maximum number of bits per second over the maximum possible distance with the fewest errors. A typical digital fiber optic link is depicted in Figure 1. Electrical data signals are converted to optical signals via a modulator. A " 1 " is transmitted as a pulse of light while a " 0 " has no light output. The num...
