Cov Rijndael algorithm yog ib tiam tshiab symmetric block cipher uas txhawb nqa qhov loj me ntawm 128, 192 thiab 256 khoom, nrog cov ntaub ntawv tuav hauv 128-ntsis blocks - txawm li cas los xij, dhau ntawm AES cov qauv tsim, qhov thaiv qhov ntau thiab tsawg tuaj yeem tsom rau cov yuam sij.

Ntawm no, Rijndael algorithm ua haujlwm li cas?

Ntawm Rijndael , encryption yog ua tiav nrog 128, 192, lossis 256-ntsis tus yuam sij, uas muab kev ruaj ntseg ntxiv rau kev tawm tsam brute-force. Tsis tas li ntawd, txoj kev encryption no ua haujlwm peb zaug sai dua DES hauv software. AES tau pom zoo hauv Tebchaws Meskas rau cov ntaub ntawv pov thawj kev nyab xeeb siab ntawm tsoomfwv.

Tsis tas li ntawd, qhov twg encryption algorithm yog raws li rijndael? AES

Tsis tas li ntawd, qhov txawv ntawm Rijndael thiab AES yog dab tsi?

AES muaj qhov ruaj khov loj ntawm 128 khoom thiab qhov loj me ntawm 128, 192, lossis 256 khoom, whereas Rijndael tuaj yeem teev nrog thaiv thiab qhov loj me hauv ib qho ntawm ntau yam ntawm 32 khoom, nrog a yam tsawg kawg ntawm 128 ntsis thiab qhov siab tshaj plaws ntawm 256 ntsis. AES yog tus ua tiav ntawm Data Encryption Standard (DES).

AES algorithm txhais li cas?

Advanced Encryption Standard, los yog AES , yog symmetric block cipher xaiv los ntawm tsoomfwv Meskas los tiv thaiv cov ntaub ntawv sib cais thiab raug siv los ntawm software thiab kho vajtse thoob plaws ntiaj teb los encrypt cov ntaub ntawv rhiab.
