Tam sim no, nrog ua kom muaj nuj nqis them rau kev ceev ntiag tug kev ruaj ntseg, tiv thaiv eavesDropping tau dhau los ua ntau tus neeg thiab cov tsev haujlwm los xyuas cov ntaub ntawv kev nyab xeeb. Txhawm rau kom ua tiav qhov tseeb thiab tiv thaiv zoo anti-eavesDropping nrhiav tau, cov cuab yeej siv kev tshaj lij yog qhov tseem ceeb. Muaj kev sib txawv thiab muaj peev xwm tsom anti-eavesdropping thiab anti-koob yees duab kev daws teeb meem yog tam sim no muaj rau cov xwm txheej sib txawv.
Ua ntej, tiv thaiv eavesDropping nrhiav tau cov khoom siv uas muaj
XOV TOOJ CUA KUAJ NTSUAM TSIM NTES NTES
Xov tooj cua tau ntsuas ntsuas ntsuas yog ib qho ntawm cov khoom tseem ceeb ntawm kev tawm tsam eavesdropping. Nws tuaj yeem luam theej duab thiab saib xyuas xov tooj cua ntsuas teeb tsa hauv qee qhov ntau zaus. Thaum lub tshuab mloog ua haujlwm, nws emits lub xov tooj cua tau teeb liab ntawm qhov qee zaus los muab cov ntaub ntawv raug nyiag. Xov tooj cua tau ntsuas ntsuas los ntawm kev ntes cov cim no, raws li lub zog ntawm lub teeb liab, thiab cov zaus ntawm qhov chaw muaj peev xwm ntawm lub mloog. Piv txwv li, qee qhov kawg RF cov teeb liab detectors muaj peev xwm ntes tau cov cim hluav taws xob sai sai, txawm tias eavicdrop li muab zais hauv cov phab ntsa thiab rooj tog zaum cov rooj tog yog qhov nyuaj nkaum.
Nonlinear Node Ntes
Cov cuab yeej siv tau tsuas yog siv los kuaj cov hluav taws xob hauv nruab rau ntau yam khoom. Ntau cov khoom siv eAvesdropping yog ntse camouflaged lossis zais rau lub hom phiaj ntawm kev zais. Tus Nonlinear Nig Ntes siv cov neeg nonlinear ntawm cov tshuab hluav taws xob. Thaum lub teeb liab ntawm ib qho zaus muaj kev cuam tshuam rau lub hom phiaj uas cov khoom siv hluav taws xob uas tsis muaj kev sib raug zoo xws li cov khoom siv sib raug zoo los ntawm kev ntes cov cim lus teb no. Zoo li qee cov yoov disguised li cov khoom niaj hnub, xws li mloog cov khoom ua ke raws li cov teeb pom kev zoo li cov khoom siv thiab cov cim detectors muaj peev xwm txheeb tau.
Infrared Ntes
Infrared detectors tuaj yeem ua lub luag haujlwm tseem ceeb hauv koob yees duab-hom eavesdropping cov khoom siv nrog infrared sau teeb. Hauv qhov chaw tsaus nti, kom ua tiav cov khoom siv ntshiab, cov khoom siv tsis tau muaj teeb meem, tab sis tib neeg lub qhov muag tsis tuaj yeem ntes cov cim phiaj xwm. Los ntawm infrared scanning ntawm ib puag ncig, ib zaug txawv txawv infrared teeb pom, nws yuav txhais tau tias muaj cov khoom siv ntawm kev sib tw ntawm kev thaij duab thiab eavesdroping khoom. Hauv kev soj ntsuam cov chav tsev so chav tsev, chav rau khoom thiab lwm qhov chaw, infrared detectors tuaj yeem tshawb pom cov koob yees duab sai sai.
Cov Ancuab Spectrum Analyzer
Spectrum analyzer tuaj yeem txheeb xyuas cov zaus, qhov nrawm thiab lwm yam teeb liab ntawm hluav taws xob hluav taws xob. Hauv kev tshawb nrhiav anti-eavesDropping Nrhiav tau, nws tuaj yeem nthuav tawm cov cim hluav taws xob tau txais cov cim hluav taws xob hauv daim ntawv ntawm cov duab kos. Los ntawm kev txheeb xyuas lub spectrogram, cov kws tshaj lij muaj peev xwm txheeb xyuas cov cim ntsuas cim tshwj xeeb yog tsim los ntawm kev mloog lub suab thaum nws ua qhov txawv ntawm cov cim ntawm cov khoom siv ib txwm muaj. Piv txwv li, ntau hom eavesdropping li tej zaum yuav muaj cov cim ntsuas cim cim tau ntes cov cwj pwm tshwj xeeb, thiab cov khoom lag luam zoo nkauj tuaj yeem pab cov kws kuaj xyuas cov khoom lag luam.
Thib ob, kev daws teeb meem rau cov xwm txheej sib txawv
Los tiv thaiv tub sab nyiag khoom ntawm cov tsheb
Nrhiav tau cov khoom siv: hauv kev tawm tsam tub sab nraud ntawm cov tsheb, muaj ntau yam khoom siv yuav raug muab sib xyaw. Ua ntej tshaj plaws, lub xov tooj cua ntsuas ntsuas ntsuas yog siv los ua qhov kev tshawb fawb sab hauv thiab ib puag ncig ntawm GPS tsis raug cai thiab xov tooj cua nrawm teeb tsa tawm los ntawm cov cuab yeej mloog. Vim tias cov cuab yeej siv no tuaj yeem ntsia tau los ntawm cov tub rog raug ntsia rau taug qab rau taug qab lossis eavesdropping thaum lub tsheb yog tsav, lub RF teeb liab ntes tuaj yeem nrhiav cov khoom siv tau sai sai. Nyob rau tib lub sijhawm, cov nonlinear note ntes yog siv los ua tib zoo tshuaj xyuas ntau lub zog ntawm lub tsheb, lub rooj zaum, kom tiv thaiv cov hluav taws xob eavesdround. Los ntawm kev sim siab tshaj plaws, tus tswv lub tsheb tuaj yeem daws cov khoom zais cia los ntawm lub tsheb tsis raug cai, thiab paub meej tias tus tswv tsheb mus ncig ua si tsis yog leaked.
Tus Kheej Tsev Neeg Qhov Chaw Los Tiv Thaiv Tub Sab Tub Sab
Nrhiav cov khoom siv tau: Rau tsev neeg saib ntawm tus kheej, siv infrared detectors los xyuas chav pw, chav dej thiab lwm yam kom tiv thaiv cov koob yees duab zais ntawm kev thaij duab. Nyob rau tib lub sijhawm, lub xov tooj cua siv xov tooj cua taw qhia tau ntes yog siv los tshawb xyuas qhov chaw uas muaj sia nyob rau seb puas muaj lub tshuab mloog. Ib qho ntxiv, nonlinear no detectors yog siv los kuaj cov cuab yeej hluav taws xob thiab kev ua kom cov tub sab tub nyiag dab tsi tuaj yeem zam cov khoom siv eavesdraphe uas cov khoom niaj hnub. Txhawm rau tiv thaiv tus kheej ntiag tug thiab tsev neeg kev nyab xeeb, yog li cov neeg muas zaub tuaj yeem nyob nrog kev thaj yeeb ntawm lub siab.
Los tiv thaiv tub sab nyiag khoom los ntawm kev tsim khoom lag luam
Cov khoom siv soj ntsuam: Hauv cov tsev lag luam ua lag luam, kev siv ntau hom kev thev naus laus zis thiab cov cuab yeej siv rau kev sim siab. Cov tshuaj anectrum spectrum ua cov ncauj lus kom ntxaws ntxaws ntawm lub electromagnetic ib puag ncig hauv thaj chaw ua haujlwm kom paub cov phiajcim txawv txawv. RF cov paib detectors thiab notlinear no detectors yuav nyob rau hauv txhua txhua kaum ntawm chav ua haujlwm, cov khoom siv rau cov ntaub ntawv, thiab lwm yam. Ib qho ntxiv, kev tshaj lij kuaj cov cuab yeej siv network los txheeb xyuas lub koom haum cov haujlwm network kom tiv thaiv cov neeg nyiag khoom los ntawm kev tawm suab. Cov ntaub ntawv tsis pub lwm tus paub txog cov koomhaum ua lag luam muaj feem xyuam rau kev muaj sia nyob thiab kev txhim kho kev lag luam. Los ntawm kev sim siab tshaj plaws, nws tiv thaiv cov kev tsis pub luam tawm los ntawm kev ua kom muaj kev lees paub ruaj khov ntawm kev ua lag luam cov tsev lag luam.
Tub ntxhais tshwj xeeb tso tawm los tiv thaiv tub sab nyiag khoom
Cov khoom siv kuaj: Rau cov chaw zais ntshis, cov cuab yeej ntsuas siab thiab thev naus laus zis siv. Ntxiv rau ntau hom khoom tau hais los saum no, qee cov khoom siv customized tsim tshwj xeeb rau cov chaw muaj kev nyab xeeb yuav tsum tau siv. Piv txwv li, RF cov teeb liab detectors nrog cov qhab nia ntau dua thiab rhiab tuaj yeem pom cov cim tsis muaj zog; Cov khoom siv tshuaj xyuas siv cov noob encryption tshuab ua kom muaj kev ruaj ntseg thiab tsis pub lwm tus paub txog cov txheej txheem kev pom nws tus kheej. Muab kev tiv thaiv kev tiv thaiv ntau thiab ntau yam tshwj xeeb rau cov chaw zais ntshis. Los ntawm cov neeg ua yeeb yam ntawm tus kheej hauv lub xaib, kom tau kev soj ntsuam tiag tiag, thiab tom qab ntawd kom muaj kev nyab xeeb rau kev tiv thaiv kev ceev ntiag tug thiab kev nyab xeeb ntawm cov tseem ceeb zais cia.
Nruab nrog cov khoom siv paub thiab cov kev daws teeb meem rau tus kheej rau cov neeg siv khoom sib txawv, ua haujlwm tseem ceeb hauv kev tiv thaiv kev tiv thaiv ntiag tug.
