A crypto txiaj algorithm, los yog cipher, yog kev ua lej siv nyob rau hauv cov txheej txheem encryption thiab decryption. A crypto txiaj algorithm ua haujlwm ua ke nrog tus yuam sij - ib lo lus, tus lej, lossis kab lus - txhawm rau nkag mus rau cov ntawv nyeem. Tib daim ntawv dawb encrypts rau txawv ciphertext nrog cov yuam sij sib txawv.

Kuj nug, siv crypto txiaj li cas?

Cryptography tso cai rau koj kom muaj kev ntseeg siab hauv koj cov khoom siv hluav taws xob. Encryption yog siv hauv kev lag luam hluav taws xob los tiv thaiv cov ntaub ntawv xws li tus lej account thiab cov nyiaj hloov pauv, kos npe digital hloov cov ntawv kos npe los yog daim credit card tso cai, thiab pej xeem-key encryption muab kev ceev ntiag tug.

Tom qab, lo lus nug yog, pes tsawg tus cryptographers ua? Kev tshaj lij cryptographers yuav tsum muaj tsawg kawg yog bachelor's degree hauv computer science, lej lossis lwm yam haujlwm. Hais txog nyiaj hli, lawv ua qhov nruab nrab ntawm $ 144, 866 txhua xyoo nrog ntau yam uas yog $ 107, 000 ntawm qhov qis kawg thiab $ 189, 500 ntawm nws qhov siab tshaj.

Kuj Paub, dab tsi yog cryptoography nrog piv txwv?

Cryptography . Hnub no, cryptoography yog siv los tiv thaiv cov ntaub ntawv digital. Nws yog ib qho kev faib ntawm computer science uas tsom rau kev hloov cov ntaub ntawv mus rau hauv cov hom ntawv uas tsis tuaj yeem lees paub los ntawm cov neeg siv tsis tau tso cai. Ib piv txwv ntawm qhov yooj yim cryptoography yog cov lus encrypted uas cov ntawv hloov nrog lwm cov cim.

Muaj pes tsawg hom cryptography muaj?

Peb hom cryptography : secret-key, public key, and hash function. Hom ntawm kwj ciphers. Feistel ntawv cipher. Kev siv peb crypto txiaj cov txheej txheem rau kev sib txuas lus ruaj ntseg.
