Symmetric encryption yog ob txoj kev algorithm, vim hais tias tus lej algorithm yog thim rov qab thaum lub sij hawm decryption ntawm cov lus los ntawm tib lub zais tus yuam sij . Symmetric encryption , kuj nrov hu ua private- key encryption & ruaj ntseg- key encryption.
Ib yam li ntawd, koj yuav nug, vim li cas lo lus symmetry siv nyob rau hauv symmetric key encryption?
Symmetrical encryption yog cov txheej txheem qub thiab paub zoo tshaj plaws. Nws siv qhov zais cia tus yuam sij uas tuaj yeem yog tus lej, a lus los yog ib txoj hlua ntawm cov ntawv random. Lub ntsiab tsis zoo ntawm lub symmetric key encryption yog tias txhua tog koom nrog yuav tsum tau pauv qhov siv key rau encryption cov ntaub ntawv ua ntej lawv tuaj yeem decrypt nws.
Tsis tas li ntawd, yog vim li cas symmetric encryption kuj hu ua tus yuam sij cryptography? Private key encryption yog hu ua symmetric encryption , qhov twg tib yam tus yuam sij ntiag tug yog siv rau ob leeg encryption thiab lub hom phiaj decryption. A tus yuam sij ntiag tug feem ntau yog ib tug ntev, randomly generated tooj uas tsis tau yooj yim twv. Txij li thaum tsuas yog ib qho tus yuam sij muaj kev koom tes, cov txheej txheem yog ceev thiab yooj yim.
Ua kom pom qhov no, txhais tau li cas los ntawm qhov tseem ceeb encryption?
Symmetric encryption yog ib encryption methodology uas siv ib leeg tus yuam sij rau encryption (encode) thiab decrypt (decode) cov ntaub ntawv. Nws yog cov txheej txheem qub tshaj plaws thiab paub zoo tshaj plaws rau encryption . Qhov zais cia tus yuam sij tuaj yeem yog lo lus, tus lej, lossis ib txoj hlua ntawm cov tsiaj ntawv, thiab nws siv tau rau cov lus.
Qhov twg yog symmetric encryption siv?
Nyob rau hauv cov ntaub ntawv ntawm ib tug database, qhov zais cia tus yuam sij tej zaum tsuas yog muaj rau database nws tus kheej rau encryption los yog decrypt. Qee qhov piv txwv ntawm qhov twg symmetric cryptography yog siv yog: daim ntawv thov kev them nyiaj, xws li daim npav rho nyiaj uas PII xav tau kev tiv thaiv los tiv thaiv tus neeg nyiag los yog tus nqi dag.

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
Yuav ua li cas yog ib tug txheej txheem nyob rau hauv lub operating system dab tsi yog ib tug xov nyob rau hauv lub operating system?
Ib tug txheej txheem, nyob rau hauv cov nqe lus yooj yim tshaj, yog ib tug executingprogram. Ib tug los yog ntau tshaj threads khiav nyob rau hauv cov ntsiab lus ntawm cov txheej txheem. Ib tug xov yog ib qho tseem ceeb chav tsev uas theoperating system faib lub sij hawm processor. Lub threadpool feem ntau yog siv los txo tus naj npawb ntawm cov ntaub ntawv thov thiab muab kev tswj hwm ntawm cov neeg ua haujlwm threads
Yuav ua li cas koj teem ib array nyob rau hauv ascending kev txiav txim nyob rau hauv Java?
Java Program los txheeb cov Array hauv Ascending Order public class Ascending _Order. int n, kub; Scanner s = new Scanner(System. System. out. print('Enter no. of elements you want in array:'); n = s. nextInt(); int a[] = new int[n]; System.out . println('Enter all the elements:'); for (int i = 0; i < n; i++)
Vim li cas kev sib raug zoo algebra siv nyob rau hauv kev sib raug zoo database tswj?
RELATIONAL ALGEBRA yog ib hom lus nug uas siv dav heev. Nws sau cov xwm txheej ntawm kev sib raug zoo raws li kev tawm tswv yim thiab muab qhov tshwm sim ntawm kev sib raug zoo raws li cov zis. Nws siv ntau yam haujlwm los ua qhov haujlwm no. Relational algebra operations yog ua recursively ntawm kev sib raug zoo
Dab tsi asymmetric encryption algorithm yog siv rau symmetric key pauv?
Qhov feem ntau siv symmetrical algorithm yog AES-128, AES-192, thiab AES-256. Lub ntsiab tsis zoo ntawm tus yuam sij symmetric encryption yog tias txhua tus neeg koom nrog yuav tsum tau pauv tus yuam sij siv los encrypt cov ntaub ntawv ua ntej lawv tuaj yeem decrypt nws
