symmetrical algorithms : (tseem hu ua "tus yuam sij zais cia") siv tib tus yuam sij rau ob qho tib si encryption thiab decryption; asymmetric algorithms : (tseem hu ua "public key") siv cov yuam sij sib txawv rau encryption thiab decryption. Kev faib tawm tseem ceeb: peb yuav xa cov yuam sij li cas rau cov neeg xav tau los tsim kev sib txuas lus ruaj ntseg.
Raws li txoj cai, qhov sib txawv ntawm symmetrical thiab asymmetric encryption algorithms yog dab tsi?
Qhov sib txawv ntawm Symmetric thiab Asymmetric Encryption Symmetric encryption siv ib leeg tus yuam sij uas yuav tsum tau muab qhia rau cov neeg uas yuav tsum tau txais cov lus thaum asymmetrical encryption siv ib khub pej xeem key thiab ib tug private tus yuam sij rau encryption thiab decrypt cov lus thaum sib txuas lus.
Tsis tas li ntawd, qhov twg peb tuaj yeem siv cov yuam sij symmetric thiab asymmetric? Koj tsuas xav tau asymmetrical cryptoography thaum koj xav tau rau pauv cov ntaub ntawv nrog ib tus neeg tshwj xeeb uas koj tsis muaj ib tus yuam sij pauv nrog (thiab txawm tias tom qab ntawd, koj siv symmetrical thiab encrypt tus yuam sij asymmetrically nquag) los yog thaum koj xav tau rau kos npe rau ib yam dab tsi (hauv qhov xwm txheej twg koj encryption tus hash tus nqi asymmetrically).
Tsis tas li ntawd, puas yog AES asymmetric lossis symmetric?
Yog tias tib tus yuam sij siv rau ob qho tib si encryption thiab decryption, cov txheej txheem tau hais tias yog symmetrical . Yog siv cov yuam sij sib txawv, cov txheej txheem txhais tau tias yog asymmetrical . Ob qho ntawm feem ntau siv encryption algorithms niaj hnub no yog AES thiab RSA.
Dab tsi yog asymmetric system?
Hauv kev sib txuas lus, lub sij hawm asymmetrical (kuj asymmetrical los yog tsis-symmetrical) hais txog ib yam qhov system nyob rau hauv uas cov ntaub ntawv ceev los yog kom muaj nuj nqis txawv nyob rau hauv ib qho kev taw qhia raws li piv nrog rau lwm cov kev taw qhia, nruab nrab lub sij hawm.

Dab tsi yog qhov txawv ntawm symmetrical thiab asymmetrical?
Qhov sib txawv ntawm Symmetric thiab Asymmetric encryption Symmetric encryption siv ib tus yuam sij uas yuav tsum tau muab sib koom ntawm cov neeg uas xav tau txais cov lus thaum asymmetrical encryption siv ib khub ntawm pej xeem tus yuam sij thiab tus yuam sij ntiag tug los encrypt thiab decrypt cov lus thaum sib txuas lus
Dab tsi yog symmetrical thiab asymmetric multiprocessing?
Lub ntsiab sib txawv ntawm symmetric thiab asymmetricmultiprocessing yog hais tias, nyob rau hauv symmetric multiprocessing, lub CPUs yog zoo tib yam thiab lawv muab lub ntsiab cim xeeb thaum, inasymmetric multiprocessing, CPUs tsis zoo tib yam thiab lawv ua raws li qhev-tswj kev sib raug zoo
Yuav ua li cas symmetrical thiab asymmetric yuam sij siv ua ke?
Asymmetric thiab symmetric encryption feem ntau yog siv ua ke: siv cov asymmetrical algorithm xws li RSA kom ruaj ntseg xa ib tus neeg AES (symmetric) yuam sij. Tus yuam sij symmetric hu ua tus yuam sij kev sib tham; tus yuam sij kev sib tham tshiab yuav raug xa rov qab raws sijhawm ntawm RSA. Txoj hauv kev no txhawb nqa lub zog ntawm ob qho tib si cryptosystems
Dab tsi yog qhov sib txawv ntawm lub thawv thiab lub thawv ntawv thiab lub thawv ntawv yog dab tsi?
Ib lub thawv thiab cov ntawv nplawm (qee zaum hu ua boxplot) yog ib daim duab uas nthuav tawm cov ntaub ntawv los ntawm tsib lub ntsiab lus. Nyob rau hauv ib lub thawv thiab whisker zajlus: qhov kawg ntawm lub thawv yog lub sab sauv thiab sab quartiles, yog li lub thawv spans lub interquartile ntau yam. qhov nruab nrab yog cim los ntawm ib txoj kab ntsug hauv lub thawv
Dab tsi yog kev saib xyuas thiab tsis saib xyuas kev kawm algorithms?
Saib xyuas: Tag nrho cov ntaub ntawv tau sau npe thiab cov algorithms kawm los kwv yees cov txiaj ntsig ntawm cov ntaub ntawv nkag. Unsupervised: Tag nrho cov ntaub ntawv yog unlabeled thiab cov algorithms kawm rau inherent qauv los ntawm cov ntaub ntawv input
