IC / CPU daim npav dawb wiring tsawg lub sij hawm muaj sij hawm nkag mus tswj nyeem module

IC daim npav / CPU daim npav pub dawb Lub sijhawm txwv kev nkag mus Tswj Kev Nkag Nkag Siv Kev Tswj Xyuas Niaj Hnub No yog ib qho kev tswj hwm kev tswj hwm cov cuab yeej siv, Micro tswj thev naus laus zis thiab lwm yam txuj ci siab tshaj lij. Nws tau txais kev pab tiv thaiv kev sib cuag tshuab, thiab cov ntaub ntawv yog kis tau rau hauv huab cua. Lub ciphertext encrypted los ntawm des (Cov ntaub ntawv Encryption Txheem) Algorithm zam cov teeb meem ntawm kev tiv thaiv kev ruaj ntseg hauv daim npav thiab luam tawm. Cov khoom no yog ruaj khov hauv kev ua haujlwm, Tus Neeg Siv Cov Qauv Tsim, Yav tsaus ua haujlwm, yooj yim rau nruab, Saib xyuas thiab ua haujlwm, thiab tau txais zoo los ntawm kev ua lag luam.
Cov khoom lag luam tuaj yeem ua kom pom hauv kev nkag mus, rooj rooj vag, TSIS SIV NEEG QHOV QHOV, Kev Ua Si Cov Consoles, Lub tsev sib cuam tshuam, elevators thiab lwm yam khoom siv, dav siv nyob rau hauv cov tsev nyob, lub pov haum, Tuam txhab uas muag, Vaj tse chaw ua haujlwm, Chaw ntiav pw thiab lwm qhov chaw; Tshwj xeeb tshaj yog tsim nyog rau Ofator tswj thiab tsis yooj yim cov ntaub qhwv rau kev tswj hwm tsev, Siv cov neeg siv software software tswj cov neeg siv, tuaj yeem sau cov ntawv offline, Tsawg lub sijhawm sijhawm tsawg zaus, tuaj yeem nce lub suab ua haujlwm.

Nta
Daim IC Card yog muab offline, Kev nkag mus tswj tau yog txwv rau lub sijhawm tsawg thiab sijhawm, thiab lub suab muaj txiaj ntsig zoo.
IC daim npav sector nyeem thiab sau ntawv, Txhawb nqa cov lag luam IC daim npav lossis anti-luam cpu daim npav.
Tus nyeem ntawv muaj cov txheej txheem txheej txheem uas nyeem cov ntaub ntawv tso cai sau rau hauv daim npav thiab cov xa khoom xa mus rau cov maub los.
