A monoalphabetic cipher siv kev hloov pauv tas li ntawm tag nrho cov lus , whereas polyalphabetic cipher siv ntau qhov kev hloov pauv ntawm ntau txoj haujlwm hauv cov lus, qhov twg ib chav tsev los ntawm cov ntawv plain yog mapped mus rau ib qho ntawm ntau qhov ua tau zoo hauv cov ntawv ciphertext ciphertext Ciphertext tseem hu ua encrypted lossis encoded cov ntaub ntawvvim nws muaj ib daim ntawv ntawm cov ntawv qub uas nyeem tsis tau los ntawm tib neeg lossis khoos phis tawj yam tsis muaj tus lej cim rau decrypt nws. … Decryption, tus inverse ntawm encryption, yog cov txheej txheem ntawm tig ciphertext rau hauv cov ntawv nyeem tau. https://en.wikipedia.org › wiki › Ciphertext

thiab vice versa.
Dab tsi yog qhov txawv ntawm monoalphabetic cipher thiab Caesar cipher?
1. Piv txwv ntawm monoalphabetic ciphers yuav suav nrog Caesar-hloov cipher, qhov twg txhua tsab ntawv tau hloov pauv raws li tus lej lej, thiab tus lej atbash, qhov twg txhua tsab ntawv raug kos rau tsab ntawv sib luag rau nws txog qhov nruab nrab ntawm cov tsiaj ntawv. … 2.
Tus piv txwv monoalphabetic cipher yog dab tsi?
Monoalphabetic cipher yog hloov pauv tus lej nyob rau hauv uas rau tus yuam sij muab, cov ntawv cipher rau txhua tus tsiaj ntawv dawb yog tsau thoob plaws hauv cov txheej txheem encryption. Piv txwv li, yog tias 'A' raug encrypted li 'D', rau txhua qhov tshwm sim hauv cov ntawv dawb, 'A' yuav ib txwm tau encrypted rau 'D'.
Vim li cas thiaj hu ua monoalphabetic cipher?
A Monoalphabetic cipher yog ib qho cipher uas cov tsiaj ntawv ntawm cov ntawv dawb tau kos rau cov ntawv ciphertext raws li ib tus tsiaj ntawv tus yuam sij Hloov cov ntawv ciphers ua haujlwm los ntawm kev hloov txhua tsab ntawv ntawm cov ntawv nyeem nrog lwm tsab ntawv. Vim li no, ib tug monoalphabetic cipher kuj hu ua ib qho yooj yim hloov cipher.
Puas monoalphabetic cipher muaj zog dua Polyalphabetic ciphers?
Kev piav qhia: Caesar Cipher yog ib qho piv txwv ntawm Mono-niam ntawv cipher, raws li cov tsiaj ntawv ib leeg tau encrypted lossis decrypted ib zaug. … Monoalphabetic ciphers muaj zog dua Polyalphabetic ciphers vim tias kev soj ntsuam zaus yog nyuaj rau yav dhau los.
