Cov homomorphic encryption sawv cev rau yav tom ntej ntawm cov txheej txheem cryptographic raws li nws tso cai rau koj los ua haujlwm ntawm encrypted cov ntaub ntawv tsis tas yuav decrypt nws. Txhawm rau kom tau txais txiaj ntsig ntawm PHE cov phiaj xwm yuav zoo tshwj xeeb rau kev suav huab.
Ua li no, vim li cas peb thiaj xav tau homomorphic encryption?
Homomorphic encryption pab tiv thaiv kev ncaj ncees ntawm koj cov ntaub ntawv los ntawm kev tso cai rau lwm tus los tswj nws encrypted tsim thaum tsis muaj leej twg (sib sab ntawm koj raws li tus tuav ntaub ntawv ntiag tug) ua tau nkag siab lossis nkag mus rau nws cov txiaj ntsig decrypted.
puas yog homomorphic encryption ua tau? Homomorphic encryption ua nws ua tau los soj ntsuam los yog tswj encrypted cov ntaub ntawv tsis qhia cov ntaub ntawv rau leej twg. Tom qab ntawd, tsuas yog tus neeg uas muaj tus yuam sij ntiag tug sib xws tuaj yeem nkag mus rau cov ntaub ntawv tsis muaj ntaub ntawv tom qab kev ua haujlwm thiab kev tswj xyuas tiav.
Ib yam li ib tug yuav nug, homomorphic encryption ua haujlwm li cas?
Homomorphic encryption yog ib daim ntawv ntawm encryption uas tso cai rau kev suav ntawm ciphertexts, tsim ib qho encrypted qhov tshwm sim uas, thaum decrypted, phim cov txiaj ntsig ntawm kev ua haujlwm zoo li lawv tau ua nyob rau hauv cov ntawv dawb. Homomorphic encryption tuaj yeem siv rau kev ceev ntiag tug-preserving outsourced cia thiab suav.
RSA encryption yog dab tsi?
RSA algorithm. RSA (Rivest–Shamir–Adleman) yog ib qho kev siv los ntawm cov khoos phis tawj niaj hnub rau encryption thiab decrypt lus. Nws yog asymmetric cryptographic algorithm. Asymmetric txhais tau hais tias muaj ob lub ntsiab sib txawv. Qhov no tseem hu ua public key cryptoography , vim ib tug yuam sij yuav muab rau leej twg.

Vim li cas symmetric encryption sai dua asymmetric encryption?
Rau cov txheej txheem encrypt / decrypt lub luag haujlwm, symmetrical algorithms feem ntau ua tau sai dua li lawv cov asymmetrical counterparts. Qhov no yog vim lub fact tias asymmetric cryptography yog loj heev inefficient. Symmetric cryptography yog tsim los rau kev ua haujlwm zoo ntawm cov ntaub ntawv loj
Vim li cas CCNA daim ntawv pov thawj tseem ceeb?
Tau txais ntawv pov thawj yog ib qho tseem ceeb rau kev ua tiav kev ua haujlwm hauv IT- Networking raws li nws ntxiv qhov hnyav rau koj qhov profile thiab rov pib dua. CCNA zoo li lub rooj vag tonetworking raws li nws piav qhia cov ntsiab lus kom meej. Nws yog qhov yuav tsum tau ua ua ntej rau lwm yam kev kawm xws li CCNP
Vim li cas Archimedes ntsia hlau tseem ceeb?
Cov cuab yeej no tau siv ntau yam keeb kwm. Nws tau siv los tso dej tawm ntawm cov nkoj xau thiab dej nyab mines. Cov teb ntawm cov qoob loo tau watered los ntawm kev siv cov ntsia hlau rub dej los ntawm cov pas dej thiab cov dej ntws. Nws kuj tau siv los rov qab dej nyab, piv txwv li hauv Holland qhov twg ntau thaj av nyob hauv qab dej hiav txwv
Peb puas tuaj yeem ntxig ntau qhov NULL qhov tseem ceeb hauv qhov tseem ceeb Oracle?
Ntawd yog: Thaum (1, 1, null) raug tso cai, tab sis tsis pub ntau tshaj ib zaug, kab uas muaj qhov tseem ceeb (null, null, null) hauv peb kab uas ua rau tus yuam sij tshwj xeeb raug tso cai txhua lub sijhawm - ib yam li nyob rau hauv ib kab ke
Vim li cas yog vim li cas ib txoj hauv kev tseem ceeb ntawm kev paub?
Yog vim li cas thiaj paub. Yog vim li cas feem ntau suav hais tias tsis muaj nuj nqis los ntsuas seb qhov kev lees paub, lossis txawm tias tib neeg, puas ntseeg tau. Yog vim li cas qee zaum sib txawv nrog kev xav, qhov uas cov lus hais txog kev xav thiab kev xav zoo li yuav cuam tshuam peb txoj kev tshawb nrhiav kev paub; hloov peb ntawm 'qhov tseeb
