Encryption . Nws ua cov txheej txheem ntawm encryption ntawm lub transmitter kawg thiab cov txheej txheem ntawm decryption ntawm lub receiver kawg. Encryption thiab decryption yog txoj hauv kev los tiv thaiv kev tsis pub lwm tus paub ntawm cov ntaub ntawv khaws cia hauv computer systems lossis wired hauv internet lossis lwm lub computer network.
Cia li xav txog qhov no, yuav ua li cas tshwm sim ntawm txheej nthuav qhia?
Nyob ntawm Txheej 6 ntawm Open Systems Interconnection (OSI) kev sib txuas lus qauv, lub kev nthuav qhia txheej xyuas kom meej tias cov kev sib txuas lus uas dhau los ntawm nws yog nyob rau hauv daim ntawv tsim nyog rau daim ntawv thov tau txais. Hauv lwm lo lus, nws nthuav tawm cov ntaub ntawv hauv hom nyeem tau los ntawm daim ntawv thov txheej kev xav.
Tsis tas li ntawd, cov txheej txheem twg yog siv hauv txheej nthuav qhia? Cov raws tu qauv siv yog: PPTP, SAP, L2TP thiab NetBIOS. Txheej 6, ua Kev nthuav qhia txheej : Cov haujlwm ntawm encryption thiab decryption tau txhais ntawm qhov no txheej . Nws converts cov ntaub ntawv tawm tswv yim rau hauv ib hom ntawv nyeem tau los ntawm daim ntawv thov txheej . Cov hauv qab no yog cov kev nthuav qhia txheej txheej txheem : XDR, TLS, SSL thiab MIME.
Ib yam li ntawd, kev txhais lus hauv kev nthuav qhia txheej yog dab tsi?
Cov kev nthuav qhia txheej ua tus txhais lus ntawm daim ntawv thov thiab lub network, feem ntau hais txog cov syntax sawv cev ntawm cov neeg siv cov ntaub ntawv, piv txwv li, muab formatted sawv cev thiab txhais lus cov ntaub ntawv kev pabcuam. Cov ntaub ntawv compression, decompression, encryption, decryption tau ua tiav hauv qhov no txheej.
Dab tsi OSI txheej yog encryption?
SSL los yog TLS encryption tshwm sim ntawm qhov kev nthuav qhia txheej , Txheej 6 ntawm OSI model . Hauv cov lus qhia no, kawm vim li cas encryption Nws yog ib qho tseem ceeb heev thiab yuav ua li cas qee qhov kev tawm tsam hacker tseem tuaj yeem hla SSL lossis TLS thiab hem koj lub network.

Dab tsi yog cov kev pabcuam muab rau txheej txheej network los ntawm cov ntaub ntawv txuas txheej?
Cov kev pabcuam tseem ceeb yog hloov cov ntaub ntawv pob ntawv los ntawm txheej txheej network ntawm lub tshuab xa mus rau txheej txheej network ntawm lub tshuab txais. Hauv kev sib txuas lus tiag tiag, cov ntaub ntawv txuas txheej xa cov khoom ntawm lub cev thiab lub cev nruab nrab
Kev nthuav qhia txheej ASP Net yog dab tsi?
Cov Txheej Txheem Tshaj Tawm muaj cov nplooj ntawv zoo li. aspx lossis Windows Forms cov ntaub ntawv uas cov ntaub ntawv nthuav tawm rau tus neeg siv lossis cov tswv yim raug coj los ntawm tus neeg siv. ASP.NET lub vev xaib lossis daim ntawv thov Windows Forms (UI rau qhov project) hu ua Presentation Layer
Dab tsi yog qhov zoo ntawm txheej txheej rau kev tsim qauv hauv kev khiav hauj lwm qhov system?
Nrog rau txheej txheej, txheej hauv qab yog cov khoom siv kho vajtse, thaum txheej siab tshaj plaws yog cov neeg siv interface. Lub ntsiab kom zoo dua yog simplicity ntawm kev tsim kho thiab debugging. Qhov teeb meem tseem ceeb yog txhais cov txheej txheem ntau yam. Lub ntsiab tsis zoo yog tias OS nyiam ua haujlwm tsawg dua li lwm yam kev siv
Koj tuaj yeem qhia tau li cas yog tias ib qho kev nthuav qhia yog polynomial?
Rau ib qho kev qhia los ua ib lub ntsiab lus polynomial, txhua qhov hloov pauv hauv cov lus qhia yuav tsum muaj tag nrho cov naj npawb powers (lossis lwm qhov ' nkag siab' lub zog ntawm 1, xws li hauv x1, uas ib txwm sau ua x). Ib tus lej dawb kuj tuaj yeem yog lo lus polynomial
Dab tsi yog qhov haujlwm ntawm OSI txheej txheej txheej txheej txheej txheem router ua haujlwm li cas?
Hauv Cov Qauv Qhib Kev Sib Txuas Sib Txuas (OSI) kev sib txuas lus, txheej txheej txheej txheem nyob ntawm Txheej 5 thiab tswj kev teeb tsa thiab rhuav tshem ntawm kev sib txuas ntawm ob qhov kev sib txuas lus kawg. Kev sib txuas lus ntawm ob qhov kawg yog hu ua kev sib txuas
