Abstract
So far, unconditional security communication means only has quantum communications a kind of, and electromagnetic wave secret communication then needs to use encrypted code.Comparatively, what the latter's communication information can be decoded by supercomputing in principle.The present invention proposes a kind of wire communication method with security performance identical with quantum communications, it is based on the method for discharging man made noise in a network, so that signal of communication floods completely, and at communication control processor, disturbed arrester is completely eliminated this man made noise, therefore practical communication signal quality is unaffected.The topological structure of above-mentioned man made noise's emitter, the module of interference eliminator two and circuit link is the key of the present invention.According to Shannon information theory：The method causes that signal of communication is to decode.
Description
Technical field
The invention belongs to secret and safe field in communication system, it is related to safety of physical layer method.The method can thoroughly prevent
Only signal is decrypted eavesdropping on the line in wire communication.
Background technology
Man made noise is discharged in wire communication the present invention relates to one kind, this realizes that unconditional security is communication objective accordingly.
In conventional wired networks, listener-in typically uses contact or non-contact method, on direct wiretap
The signal of transmission, and further decode information.Lack personnel's post because communication line is more long, for a long time may be caused
It is insoluble problem to give away secrets.Conventional method implementation information protection by the way of information password.But, this method for
The decoding of supercomputer will be entirely ineffective.
General principle of the present invention based on communication physical layer safety, i.e.,：When the detection signal to noise ratio of transmission information is less than one
Threshold value, then any method can not possibly decode be submerged in noise signal carry information.Accordingly, the present invention according to by
The method that man made noise is discharged on communication line so that the signal to noise ratio of listener-in is less than above-mentioned threshold value, so as to cannot steal at all
Win the confidence breath.And to communication stay of two nights side, this man made noise can be what is be completely eliminated, therefore normally entering for communication can be ensured
OK.
The content of the invention
Basic ideas of the invention are, at traditional communication receiver, to communication line (i.e.：Wiretap) release is manually
Noise, and in preposition one artificial noise jamming arrester of communication control processor, this man made noise is eliminated in real time, so that logical
Letter signal is not influenceed and is normally carried out by this man made noise, and the program is as shown in Figure 1.
Technical solutions according to the invention are as follows：
Below by invention book brief description of the drawings：
1st, jamming transmitter and interference characteristic
It is being coupled between traditional communication emitter (information source) and receiver (stay of two nights) on circuit, at receiver, is adding
One jamming transmitter, its emission interface (interface 1) is coupled the circuit that may be eavesdropped, and discharges man made noise, its system
Meter feature has randomness.
2nd, jamming transmitter power controller
The artifact power of emission interface (interface 1) transmitting of jamming transmitter can adjust：The circuit of secret communication
More long, the transmission power of man made noise is bigger, it is characterized in that transmission power is associated with line length.
3rd, interference eliminator
Interference eliminator is used to eliminate influence of the man made noise to communication control processor, and it has two input interfaces and an output
Interface, is expressed as input interface 1 and input interface 2, and output interface 1.Bind mode is as follows：
Interference eliminator input interface 1 is coupled jamming transmitter emission interface 2, unknown man made noise is changed into interference and is disappeared
Except the known disturbances of device so that interference elimination is carried out.
Interference eliminator input interface 2 is coupled communication line, with UNICOM's communication signal receiver and jamming transmitter circuit.
Interference eliminator eliminates the man made noise in its interface 2 using the man made noise of input interface 1 so that output connects
The output of mouth 1 is free of this noise.This output coupled communication control processor, to provide the pure signal from emitter.
In said process, we have ignored the influence of people's noise so that patent description of the present invention is more succinct, but does not influence
The basic effect of patent of the present invention.
4th, information protection
Because listener-in cannot be directly accessed the circuit between communication control processor and interference eliminator, so the electromagnetism of eavesdropping
Source is man made noise and signal of communication sum, in noise power and signal power ratio more than a threshold value, then any
Method is impossible to decode the information that signal is carried (eavesdropping point is shown in Fig. 1).
Implementation example example：
1st, the state that communication starts
While emitter launches signal of communication, interference hair machine launches random man made noise, and communication line is discharged
Man made noise, and its " interface 1 " power output is adjusted according to line length.
2nd, the method for work of interference eliminator
" input 2 " of the device that disappears is disturbed to receive the signal mixed with man made noise by signal of communication, its " input 1 " receives pure
Pure man made noise, then adjust this pure man made noise so that man made noise's amplitude is identical, and phase with " input 1 " for its amplitude
Position is conversely, last utilization adds computing thoroughly to eliminate man made noise so that " output interface of interference eliminator " is output as being free of
The signal of communication of man made noise.
3rd, receive and state
Communication control processor is coupled " interference eliminator output interface ", obtains the signal from communication transmitter so that communication
Carried out.
Embodiment of above is merely to illustrate the present invention, and not limitation of the present invention, about the common of technical field
Technical staff, without departing from the spirit and scope of the present invention, can also make a variety of changes and modification, therefore all
Equivalent technical scheme falls within scope of the invention, and scope of patent protection of the invention should be defined by the claims.
