ob tus yuam sij

Ua li no, muaj pes tsawg hom yuam sij muaj nyob rau hauv cryptography?

Muaj plaub qhov yooj yim hom ntawm tus yuam sij encryption : symmetrical, asymmetrical, public, thiab private. Thawj ob piav txog qhov twg yuam sij yog siv rau hauv encryption txheej txheem, thiab ob kawg piav qhia txog leej twg muaj kev nkag mus rau yuam sij.

Ib sab saum toj no, pes tsawg tus yuam sij raug siv hauv pej xeem tus yuam sij cryptography? ob tus yuam sij

Kuj Paub, yuav tsum muaj pes tsawg tus yuam sij asymmetric?

3 Teb. Yog li lawv yuav xav tau 499500 symmetric keys kom muaj kev sib txuas lus ruaj ntseg ntawm lawv txhua tus. Rau cov yuam sij asymmetric, txhua tus yuav muaj 2 tus yuam sij , yog li tag nrho ntawm 2000 tus yuam sij.

Dab tsi yog ob hom kev crypto txiaj tseem ceeb?

A crypto txiaj system feem ntau muaj cov algorithms, cov yuam sij, thiab cov chaw tswj xyuas qhov tseem ceeb. Muaj ob yam yooj yim ntawm cryptographic systems: symmetric ("private key") thiab asymmetric ("public key"). Symmetric key systems xav kom tus xa thiab tus neeg txais yuav tsum muaj tib tus yuam sij.
