Plag: Route cipher yog ib qho kev hloov pauv hloov pauv. Nws ntog nyob rau hauv qeb ntawm transposition cipher raws li nws encrypts cov ntawv dawb los ntawm rearranging nws cov ntawv.
Dab tsi yog qhov hloov pauv hloov pauv thiab nws hom?
In cryptography, transposition cipher yog ib txoj hauv kev encryption uas cov haujlwm tuav los ntawm cov ntsiab lus ntawm cov ntawv dawb (uas feem ntau yog cov cim lossis pawg ntawm cov cim) tau hloov pauv raws li qhov tsis tu ncua, kom lub ciphertext ua ib tug permutation ntawm plaintext.
Qhov twg hauv qab no yog piv txwv ntawm kev hloov pauv hloov pauv hloov pauv?
Ib qho piv txwv ntawm kev hloov pauv hloov pauv hloov pauv, yog thim rov qab qhov kev txiav txim ntawm cov ntawv hauv cov ntawv dawb. Yog li "ib qho piv txwv yooj yim" dhau los ua "ELPMAXE ELPMIS A". … Lwm hom kev hloov pauv hloov pauv yog Scytale, uas yog ib qho khoom siv encryption siv los ntawm Ancient Greeks thiab Spartans.
Dab tsi yog kev faib tawm ntawm kev hloov pauv hloov pauv?
Thaum daim duab geometric yog ib daim duab plaub lossis plaub fab, thiab cov ntawv plain tau nkag los ntawm kab thiab muab rho tawm los ntawm txhua kab, nws yog hu ua columnar transposition. Thaum siv qee txoj kev uas tsis yog kab thiab kab, nws hu ua txoj kev hloov pauv. Lwm qeb ntawm kev hloov pauv yog grille transposition.
Yuav ua li cas yog hom ntawv cipher?
