Rijndael thiab Aes Thaum Lub Kaum Hli 2, 2000, Asmeskas tsoomfwv lub koom haum National Institute of Standards and Technology (NIST) tau tshaj tawm tias Rijndael yuav dhau los ua Tus Txheej Txheem Txheej Txheem Zoo Tshaj Plaws (AES). … AES yog sib npaug rau Rijndael txwvrau qhov ntev ntawm 128 khoom thiab txhawb nqa qhov ntev ntawm 128, 192 lossis 256 khoom.
rijndael ruaj ntseg li cas?
Rijndael algorithm, ua ke nrog kev nyab xeeb qhov tseem ceeb (piv txwv li AES), yog muaj zog thiab ruaj ntseg. Qhov tseeb tsuas yog kev ntsuas ntawm encryption algorithm qhov kev ruaj ntseg yog nws qhov kev sib raug zoo thiab ua neej nyob ntev mus rau cryptanalysis thiab sim kov yeej nws los ntawm ntau tus kws sau ntawv crypto.
Puas Triple DES thiab AES tib yam?
Qhov txawv ntawm AES thiab 3DES yog qhov AES nrawm dua 3DES, thiab nws tseem muaj kev nyab xeeb dua 3DES. Lub encryption tseem ceeb ntev ntawm AES yog 128, 192, thiab 256 khoom, tab sis qhov encryption tseem ceeb ntev ntawm 3DES tseem txwv rau 56 khoom. Raws li tus qauv symmetric encryption algorithm, AES los tom qab 3DES.
Rijndael algorithm ua haujlwm li cas?
Rijndael rov tsim 10 128-ntsis yuam sij los ntawm 128-ntsis tus yuam sij. … Cov ntawv dawb kuj tseem muab faib ua 4 x 4 lub rooj (txhua hauv 128-ntsis chunks). Txhua qhov ntawm 128-ntsis cov ntawv nyeem tau ua tiav hauv 10-thooj txheej txheem (10 puag ncig ntawm 128-ntsis yuam sij, 11 ntawm 192, 13 ntawm 256). Yog li, cov cai yog tsim tom qab 10th round.
Kev encryption twg zoo dua AES?
Kev nkag musAlgorithm
AES-128 thiab AES-256 siv qhov yuav luag zoo tib yam encryption algorithm. Txhua qhov encryption algorithm siv cov txheej txheem ntawm kev ua haujlwm thiab siv lawv qee lub sijhawm lossis "rounds". Qhov sib txawv ntawm AES encryption algorithms nkaus xwb yog tus naj npawb ntawm rounds: AES-128 siv 10 thiab AES-256 siv 14.
