3 DES, AES thiab RSA yog cov algorithms uas feem ntau siv niaj hnub no, txawm tias lwm tus, xws li Twofish, RC4 thiab ECDSA kuj tau siv rau qee lub sijhawm.

Ntawm no, hom encryption twg siv feem ntau?

Lub 5 Feem ntau Encryption Algorithms

  1. Data Encryption Standard (DES) Cov Ntaub Ntawv Encryption Standard yog thawj US tsoom fwv encryption qauv.
  2. TripleDES. TripleDES (qee zaum sau 3DES lossis TDES) yog qhov tshiab, ruaj ntseg dua ntawm DES.
  3. RSA.
  4. Advanced Encryption Standard (AES)
  5. Ob ntses.

Kuj Paub, txoj kev encryption twg yog siv dav tshaj plaws thiab vim li cas? Cov feem ntau siv symmetrical algorithm yog Advanced Encryption Standard (AES), uas yog Ameslikas hu ua Rijndael. Qhov no yog tus qauv tsim los ntawm US National Institute of Standards and Technology hauv 2001 rau cov encryption Cov ntaub ntawv hluav taws xob tau tshaj tawm hauv Asmeskas FIPS PUB 197.

Tsis tas li ntawd, encryption siv niaj hnub no li cas?

Encryption yog siv hauv cov phiaj xwm nyiaj txiag hluav taws xob los tiv thaiv cov ntaub ntawv sib pauv xws li tus lej lej thiab cov nyiaj pauv, cov ntawv kos npe digital tuaj yeem hloov cov ntawv kos npe los yog daim npav rho nyiaj tso cai, thiab qhov tseem ceeb ntawm pej xeem. encryption tuaj yeem muab kev ceev ntiag tug.

Dab tsi yog qee cov txheej txheem encryption?

8 Feem ntau cov txheej txheem encryption txuag cov ntaub ntawv ntiag tug

  • Triple DES. Triple DES tau tsim los hloov qhov qub DES algorithm (Data Encryption Standard) algorithm.
