Block ciphers result in compressed output. Thaiv ciphers ua rau cov ntaub ntawv tso tawm uas loj dua li cov ntaub ntawv tawm tswv yim feem ntau. Block ciphers sai dua li kwj ciphers. Thaiv ciphers encrypt plaintext ib me ntsis ntawm ib lub sij hawm los tsim ib qho thaiv.
Dab tsi yog block cipher?
Ib thaiv cipher encrypts cov ntaub ntawv hauv cov blocks siv qhov kev txiav txim siab algorithm thiab tus yuam sij symmetricIb yam li cov kwj ciphers, feem ntau txoj kev encryption encrypt me ntsis ib los ntawm ib qho (kwj ciphers). Thaiv ciphers, ntawm qhov tod tes, encrypt 128 me ntsis blocks nrog tus yuam sij ntawm qhov ntev tau txiav txim siab: 128, 192, lossis 256 khoom.
Yuav ua li cas cov hauv qab no yog thaiv ciphers?
AES, DES, thiab 3DES yog cov piv txwv ntawm block ciphers.
Dab tsi yog thaiv cipher hauv kev ruaj ntseg cyber?
Ib thaiv cipher yog ib txoj hauv kev encrypting cov ntaub ntawv hauv cov blocks los tsim ciphertext siv tus yuam sij cryptographic thiab algorithm. Lub block cipher txheej txheem tsau-loj blocks ib txhij, as opposed to a kwj cipher, uas encrypts cov ntaub ntawv ib ntsis ib zaug.
Dab tsi yog qhov nyuaj tshaj plaws ntawm kev tsim lub cryptosystem?\?
Kev pauv pauv thiab kev tswj hwm feem ntau suav tias yog qhov nyuaj tshaj plaws ntawm kev tsim lub cryptosystem. Ntau lub cryptosystems tau ua tsis tiav vim yog qhov ua yuam kev hauv lawv cov kev tswj hwm qhov tseem ceeb, thiab txhua qhov niaj hnub cryptographic algorithms xav tau cov txheej txheem tswj xyuas qhov tseem ceeb.
