Abstract:
Disclosed is a scheme of transmitting at least two or more transmission signals, in which at least two or more pure random noise signals are contained, through multiple paths, according to one embodiment of the present invention. To implement such a scheme, a complementary noise generator may be used in a high-speed communication method and system with enhanced security according to the present invention. Here, the complementary noise generator refers to an apparatus in which a total sum of summing altogether at least two or more generated noises becomes 0. Namely, the complementary noise generator can generate m noises, and the sum of the in noises becomes 0. By injecting a plurality of noises having such feature into different paths, a channel capacity of each channel is reduced, thereby making a single wiretapping difficult. In comparison, because a receiver receiving a plurality of transmission signals with injected noises receives all noise signals and then sums up the noise signals, the noises are offset, and it is possible to effectively receive the original signal (random key K) intended for transmitting by a transmitter.

Claim (Index 11):
The method of claim  24 , further comprising generating the n number of noises, and the step of generating the n number of noises includes:\n distributing an optical source to a p number of channels (p is a natural number greater than n) by passing an output of BLS (Broaden Light Source) having a broad wavelength band to a first AWG (Arrayed Waveguide Grating); infusing to an RSOA (Reflective Semiconductor Optical Amplifier) by coupling the n number of optical source in the optical sources distributed to the p number of channels using a BS (Beam Splitter); and classifying an output of the RSOA as the n number of noises by passing a second AWG.
