Introduction
Recently, the researcher of British York university showed a kind of plan that is based on quanta, use at distributing safe information along communication circuitry, and hopeful avoids serious safe flaw successfully.
Setting
Information safety, wait for the protection of sensitive information to record of go to a doctor and bank data for example, it is one of main challenges that all companies and constituent place face the whole world.
Communication system of the standard is atttacked easily by the hacker, add secret information to be able to suffer intercept and copy. Current, the hacker can copy transmission information likely. But, if do not have a kind of method to be able to defeat solution to be added the information of close protection, still cannot read so take transmitted news.
This means information to be safety is in inside period of time, but cannot assure it however forever safe, because developing medium super computer hopeful,defeat solution to be added specially close.
Innovate
Recently, the researcher of British York university showed a kind of plan that is based on quanta, use at distributing safe information along communication circuitry, and hopeful avoids serious safe flaw successfully.
This research got British project and science research council (EPSRC) of quanta communication center and Qubiz of quanta innovation center aid financially, relevant paper is published at " physics comments on wall bulletin (Physical Review Letters) " .
Technology
The researcher of York university studied one kind is based on the prototype with mechanical quanta, it has the flaw that hopes escape has communication system not only, and let information be in future also is safety.
Dr. Cosmo Lupo that science of York university computer fastens expresses: "Quanta is mechanical had obtained great progress, but we still are facing the major problem that must be solved through farther experiment. But we still are facing the major problem that must be solved through farther experiment..
"Among them a problem, it is the detector of the photon that the hacker can pass interference to be used at collect and be being measured to carry message, attack is used at the electronic equipment that information transmits. Attack is used at the electronic equipment that information transmits..
"Because we assume given device can work according to its technical standards, will execute its mission accordingly, such attack means is very so fierce. If the hacker can atttack detector to change its work way, so security is affected inevitably. So security is affected inevitably..
"However, although the working way of incorrect electron equipment makes hypothesis, mechanical principle also can assure quanta communication is safe. Divide these hypothesis through going, we can pay price to lower communication rate, but raised safe level however. But raised safe level however..
Researcher is not to depend on the electronic component that may be affected to detect and be read take news, on the detached dot in if do not get system of trustful communication of detector consist in,discovering however, between catapult and receiver a certain place, communication will become safe a lot of.
Detector can receive the combination of two kinds of signal, one kind comes from catapult, another kind comes from receiver. Detector can be read only take signal of this kind of combination, and cannot read the component that takes it.
Value
Dr. Lupo expresses: "In our research, we were offerred not only plant about this ' detector - independent ' first of the design strict maths proof, and also consider a kind of as compatible as network of existing and fiber-optic communication plan. And also consider a kind of as compatible as network of existing and fiber-optic communication plan..
"As a whole, our plan came true to span the cannot cut interpret code trade of the internet network, and won't bring major change to actual infrastructure. And won't bring major change to actual infrastructure..
"We still are in prototype stage, but the way that reduces these systematic cost through searching, we will be more adjacent let quanta communication turn into real cause. We will be more adjacent let quanta communication turn into real cause..
Key word
Quanta adds safety of communication of close, quanta, information
