Laser Security System
With the increasing power of computers, the previous generation of the encryption system will collapse. Now scientists have discovered a "conquering" of the encryption system, possibly in the near future, our information will never be stolen.This method requires data transmission by laser 5000mw, the main idea is to convert information into no coherent photon beam, so that even if the monitoring information in the line, to see just a bunch of disorganized photons only. However, this method requires a special conversion system, and that only the sender and receiver both hold, so that only the parties can decrypt this information. The experiment is a research institute of the University of Massachusetts organization, and now they are developing the system conversion.
The complete system technique called pulse position modulation (pulse position modulation), the time will be divided into disparate intervals, each interval represents a letter or a symbol. 20000mw laser pen pulses will assume operating signal transmission. Coding interval and only the recipient share: only the recipient can decode.
The researchers said the transfer pulse information contains only a small amount of photons, but the information which exists in a large number of optical fiber irrelevant photons. The purpose of the converter is to cut information, and it looks like background noise signal. For the average light sensor, when they received an unknown photon, they will take the initiative to ignore, so as to achieve the role of secrecy. Let it be assumed that the sender information to be in line for a long time that this information will be better integration and background signal: if the message to disappear.
The researchers were able to demonstrate the system, but they did not specify who would use such a security system. Most people only care about important information for the contents confidential, such as: national intelligence, trade secrets, this method is very suitable to convey information. But this laser 3000mw system has a huge drawback is that prior to the recipient to decode the code, the code to be decoded by what means confidentiality is a big problem.
