Cryptography yog kev kawm txog lub tswvyim zoo li Encryption , decryption, siv los muab kev sib txuas lus ruaj ntseg whereas encryption yog tus txheej txheem ntawm encoding lus nrog ib tug algorithm.
Ntxiv mus, dab tsi yog encryption hauv cryptography?
Hauv cryptoography , encryption yog tus txheej txheem ntawm encoding ib cov lus los yog cov ntaub ntawv nyob rau hauv xws li ib tug txoj kev uas tsuas yog ob tog tau tso cai nkag tau rau nws thiab cov neeg uas tsis tau tso cai tsis tau. Encryption tsis yog nws tus kheej tiv thaiv kev cuam tshuam tab sis tsis lees paub cov ntsiab lus nkag siab rau tus neeg xav tau cuam tshuam.
Tsis tas li ntawd, dab tsi yog encryption thiab decryption hauv cryptography? Encryption yog tus txheej txheem ntawm kev txhais cov ntaub ntawv dawb (plaintext) rau hauv ib yam dab tsi uas zoo nkaus li yog random thiab tsis muaj ntsiab lus (ciphertext). Kev txiav txim siab yog tus txheej txheem ntawm converting ciphertext rov qab rau plaintext. Ib tus yuam sij symmetric yog siv thaum lub sij hawm ob qho tib si encryption thiab decryption txheej txheem.
Ntxiv mus, peb hom cryptography yog dab tsi?
Peb hom cryptoography : secret-key, public key, and hash function. Hom ntawm kwj ciphers. Feistel ntawv cipher. Kev siv cov peb cryptographic cov txheej txheem rau kev sib txuas lus ruaj ntseg.
Ib qho piv txwv ntawm encryption yog dab tsi?
Encryption txhais tau tias yog kev hloov dua siab tshiab ntawm ib yam dab tsi rau cov cai lossis cov cim kom nws cov ntsiab lus tsis tuaj yeem nkag siab yog tias cuam tshuam. Thaum xa email tsis pub lwm tus paub thiab koj siv qhov kev pab cuam uas tsis pom nws cov ntsiab lus, qhov no yog ib qho piv txwv ntawm encryption.

Puas yog USB C zoo ib yam li HDMI?
Cov lus teb luv luv: USB hom C cables muaj peev xwm hloov HDMI cables, tab sis HDMI yuav nyob hauv USB hom C cables. Yog li tsis yog, USB hom C yuav tsis hloov HDMI, nws tsuas yog muab HDMI txuas rau hauv daim ntawv sib txawv. HDMI yog ob qho tib si lub cev txuas thiab cov lus sib txuas lus, mob siab rau video
Puas yog elliptic nkhaus cryptography Quantum Secure?
Supersingular elliptic nkhaus isogeny cryptography Yog hais tias ib tug siv elliptic nkhaus taw tes compression rau pej xeem tus yuam sij yuav tsum tsis txhob ntau tshaj 8x768 los yog 6144 khoom nyob rau hauv ntev. Qhov no ua rau tus naj npawb ntawm cov khoom sib kis sib npaug rau qhov tsis yog-quantum ruaj ntseg RSA thiab Diffie-Hellman ntawm tib qib kev ruaj ntseg classical
Puas yog bytes thiab cov cim zoo ib yam?
Cov cim tsis zoo ib yam li bytes. Lub sij hawm tus cwj pwm yog ib lub ntsiab lus ntawm lub ntsiab lus (lub ntsiab lus nws txhais ib yam dab tsi ntawm txoj kev uas tib neeg xav txog tej yam). Lub sij hawm byte yog ib lub sij hawm ntaus ntawv (lub ntsiab lus nws txhais ib yam dab tsi nyob rau hauv cov nqe lus ntawm txoj kev kho vajtse tau tsim). Qhov txawv yog nyob rau hauv lub encoding
Vim li cas symmetric encryption sai dua asymmetric encryption?
Rau cov txheej txheem encrypt / decrypt lub luag haujlwm, symmetrical algorithms feem ntau ua tau sai dua li lawv cov asymmetrical counterparts. Qhov no yog vim lub fact tias asymmetric cryptography yog loj heev inefficient. Symmetric cryptography yog tsim los rau kev ua haujlwm zoo ntawm cov ntaub ntawv loj
Dab tsi yog qhov txawv ntawm kev sib raug zoo unary kev sib raug zoo binary thiab kev sib raug zoo ternary?
Kev sib raug zoo tsis sib xws yog thaum ob tus neeg koom hauv kev sib raug zoo yog tib lub koom haum. Piv txwv li: Cov ncauj lus yuav yog qhov yuav tsum tau ua ua ntej rau lwm yam kev kawm. Kev sib raug zoo ternary yog thaum peb lub koom haum koom nrog kev sib raug zoo
