Niaj hnub nimno cryptography . Encryption hauv niaj hnub lub sij hawm yog tiav los ntawm kev siv algorithms uas muaj tus yuam sij rau encryption thiab decrypt cov ntaub ntawv. Cov yuam sij no hloov cov lus thiab cov ntaub ntawv mus rau "digital gibberish" dhau los encryption thiab tom qab ntawd xa lawv mus rau daim ntawv qub los ntawm kev decryption.
Nyob rau hauv txoj kev no, encryption siv niaj hnub no li cas?
Encryption yog siv hauv cov phiaj xwm nyiaj txiag hluav taws xob los tiv thaiv cov ntaub ntawv sib pauv xws li tus lej lej thiab cov nyiaj pauv, cov ntawv kos npe digital tuaj yeem hloov cov ntawv kos npe los yog daim npav rho nyiaj tso cai, thiab qhov tseem ceeb ntawm pej xeem. encryption tuaj yeem muab kev ceev ntiag tug.
Ib sab saum toj no, dab tsi yog encryption piav qhia? Kev txhais cov ntaub ntawv mus rau hauv ib tug zais cia code. Encryption yog txoj hauv kev zoo tshaj plaws kom ua tiav cov ntaub ntawv kev ruaj ntseg. Nyeem ib encrypted cov ntaub ntawv, koj yuav tsum muaj kev nkag mus rau tus yuam sij zais lossis lo lus zais uas tso cai rau koj decrypt nws. Unencrypted cov ntaub ntawv yog hu ua cov ntawv dawb; encrypted cov ntaub ntawv raug xa mus ua cov ntawv cipher.
Tsis tas li ntawd, niaj hnub ciphers yog dab tsi?
Niaj hnub . Niaj hnub algorithms yog cov uas siv nyob rau hauv tam sim no technology e.g. thaiv ciphers , pej xeem tseem ceeb cryptosystems thiab lwm yam. Cov alogrithms no muaj kev nyab xeeb heev (txawm li cas los lawv yuav tsis siv), tab sis nyob rau hauv ntau zaus peb muaj peev xwm xyaum nyob rau hauv tsis muaj zog versions ntawm lub algorithms.
Dab tsi yog hom encryption?
Peb qhov loj hom encryption yog DES, AES, thiab RSA. Thaum muaj ntau hom encryption - ntau dua tuaj yeem piav qhia yooj yim ntawm no - peb yuav saib peb qhov tseem ceeb no hom encryption uas cov neeg siv khoom siv txhua hnub.

Dab tsi yog niaj hnub block cipher?
Lus Txhais • Ib tug symmetric tseem ceeb niaj hnub thaiv cipher encrypts ib n-ntsis thaiv ntawm plaintext los yog decrypts ib n-ntsis thaiv ntawm ciphertext. • Lub encryption lossis decryption algorithm siv tus yuam sij k-ntsis
Dab tsi yog periscope siv rau niaj hnub no?
Ib lub periscope cia koj pom cov khoom saum toj kawg nkaus, xws li laj kab lossis phab ntsa uas koj tsis siab txaus saib. Koj tuaj yeem siv nws los saib ib ncig ntawm cov ces kaum. Periscopes tseem siv niaj hnub no hauv cov tso tsheb hlau luam thiab qee qhov submarines. Ib qho yooj yim periscope tsuas yog ib lub raj ntev nrog daim iav ntawm txhua qhov kawg
Dab tsi yog qhov feem ntau encryption algorithms siv niaj hnub no?
3DES, AES thiab RSA yog cov algorithms uas feem ntau siv niaj hnub no, txawm tias lwm tus, xws li Twofish, RC4 thiab ECDSA kuj tau siv rau qee qhov xwm txheej
Dab tsi yog cov algorithms uas nquag siv niaj hnub no?
Google's Ranking Algorithm (PageRank) tuaj yeem yog qhov siv ntau tshaj plaws. Nws qhov cuam tshuam / cuam tshuam rau lub ntiaj teb: PageRank yog, sib cav, siv cov algorithm tshaj plaws hauv ntiaj teb niaj hnub no
