Cov ntsuas hluav taws xob them ua ntej siv cov ntaub ntawv encryption thev naus laus zis, siv 3DES encryption algorithm, kos npe digital, thiab hash digest algorithms los encrypt thiab tiv thaiv cov ntaub ntawv rhiab, xws li cov neeg siv hluav taws xob siv cov ntaub ntawv. Cov ntsuas no suav nrog Embedded Secure Access Module (ESAM)-feem ntau muaj lub CPU nti hauv SOP lossis DIP ntim- khaws cov ntaub ntawv tseem ceeb thiab ua cryptographic encoding; qhov module no tseem txhawb nqa kev tswj hwm tseem ceeb los txhim kho tag nrho cov kab ke kev ruaj ntseg thiab kev ruaj ntseg. Lub kaw lus tsim kom muaj kev tswj hwm kev tswj hwm nruj, suav nrog ntau yam kev tiv thaiv kev nyab xeeb- suav nrog kev lees paub tus password muaj zog- kom ntseeg tau tias tsuas yog cov neeg ua haujlwm tau tso cai tuaj yeem ua haujlwm tau. Txhawm rau txo cov kev pheej hmoo ntawm kev nyab xeeb cuam tshuam nrog kev sib txuas lus wireless (xws li RFID cim npe), lub kaw lus siv kev sib txuas lus kev ruaj ntseg thev naus laus zis-xws li cim cim cim cim npe- los muab kev tiv thaiv zoo.
Cov chaw taws teeb them ua ntej hluav taws xob siv hluav taws xob siv ntau txoj hauv kev sib txuas lus. RS-485 wired kev sib txuas lus xa cov ntaub ntawv hla cov kab hluav taws xob uas twb muaj lawm, muab cov yam ntxwv xws li kev ruaj ntseg, kev ntseeg siab, kev kub ceev, thiab muaj zog tiv thaiv kev cuam tshuam . 4G wireless kev sib txuas lus, raws li cov xov tooj ntawm tes, muab kev pab cuam dav dav thiab kev sib kis ceev, ua rau nws haum rau ntev - cov ntaub ntawv xa mus. NB-IoT wireless IoT kev sib txuas lus muaj kev siv hluav taws xob tsawg, muaj peev xwm sib kis tau ntev, thiab kev txhawb nqa rau kev sib txuas ntawm cov cuab yeej loj, ua rau nws zoo tagnrho rau cov xwm txheej hla ntau lub xeev lossis lub nroog, nrog rau ib puag ncig nrog cov xwm txheej nyuaj sib kis. Fais Fab Kev Sib Txuas Lus (PLC) siv cov kab hluav taws xob uas twb muaj lawm ua qhov nruab nrab ntawm kev sib kis, tshem tawm qhov xav tau kev sib txuas lus txuas ntxiv thiab muab qhov zoo xws li tus nqi qis thiab ntau yam kev siv.
Cov ntsuas hluav taws xob them ua ntej siv Smart Meter Analog Pem Hauv Ntej-End (AFE) IC kom ua tiav siab - qhov ntsuas DC thiab AC zog; qhov no ua rau qhov ntsuas qhov tseeb ntawm qhov tam sim no tsawg kawg nkaus - xws li cov khoom siv hauv tsev hauv hom standby .
"Malicious Load" kev txheeb xyuas cov cuab yeej siv los txwv kev sib txuas ntawm cov khoom tsis raug cai lossis tsis raug tso cai rau cov ceg txuas tshwj xeeb. Thaum lub ntsuas ntsuas pom qhov kev sib txuas ntawm qhov tsis raug tso cai ua haujlwm tsis zoo- feem ntau yog tus cwj pwm los ntawm kev siv hluav taws xob loj thiab muaj qhov nce ntxiv ntau ntxiv - nws tuaj yeem ua rau muaj kev mus ncig los txiav tawm cov ceg ntoo cuam tshuam.
