RSA lossis Rivest-Shamir-Adleman encryption algorithm yog ib daim ntawv muaj zog tshaj plaws ntawm encryption hauv ntiaj teb no. Nws txhawb nqa qhov ntev ntawm qhov tseem ceeb, thiab nws yog qhov raug pom 2048- thiab 4096- ntsis yuam sij. RSA yog asymmetrical encryption algorithm.
Tsuas yog li ntawd, dab tsi yog qhov kev ruaj ntseg cryptographic algorithm?
- AES - AES tseem hu ua Advanced Encryption Standard yog ib qho kev siv algorithm nrov heev.
- Twofish - Qhov no yog raws li Blowfish thiab yog ib qho thaiv cipher.
- 3DES - Qhov no kuj nrov npe hu ua Triple Data Encryption Standard.
Tsis tas li ntawd, qhov twg encryption algorithm yog ceev tshaj? Blowfish - nrog qhov loj me ntawm 128-ntsis txog 448-ntsis, nws suav tias yog qhov zoo dua algorithm. Blowfish yog tam sim no supersed los ntawm Twofish. 5. RC4 - Qhov loj me ntawm 40-ntsis txog 1024-ntsis, RC4 yog qhov ceev tshaj plaws java txhawb encryption algorithm.
Hauv qhov no, lub algorithm twg yog siv hauv cryptography?
Symmetric Key Algorithms. Lub symmetric tseem ceeb algorithm (tseem hu ua tus yuam sij zais algorithm), siv lub tswv yim ntawm tus yuam sij thiab ntsuas phoo txhawm rau nkag mus rau cov ntawv sau yooj yim thiab txiav txim siab. ciphertext cov ntaub ntawv. Tib "tus yuam sij" yog siv rau ob qho tib si encrypt thiab decrypt cov ntaub ntawv.
Dab tsi yog 3 yam tseem ceeb ntawm cryptographic algorithms?
Cov duab. Peb hom cryptoography : secret-key, public key, and hash function.

Dab tsi yog qhov zoo tshaj plaws algorithm rau kev soj ntsuam kev xav?
Kev soj ntsuam kev xav yog cov cuab yeej zoo sib xws uas siv los txheeb xyuas cov kev xav ntawm cov neeg siv khoom thiab muaj ntau lub algorithms tuaj yeem siv los tsim cov ntawv thov rau kev soj ntsuam kev xav. Raws li tus tsim tawm thiab ML cov kws tshaj lij SVM, Naive Bayes thiab qhov siab tshaj plaws entropy yog qhov zoo tshaj plaws saib xyuas tshuab kev kawm algorithms
Dab tsi yog qhov zoo tshaj plaws tsib qhov tsis zoo ntawm koj lub operating system?
Qhov feem ntau cov software kev ruaj ntseg vulnerabilities muaj xws li: ploj ntaub ntawv encryption. OS command txhaj. SQL txhaj. Tsis pub dhau. Tsis muaj kev lees paub rau kev ua haujlwm tseem ceeb. Kev tso cai ploj lawm. Unrestricted upload cov ntaub ntawv txaus ntshai hom. Kev cia siab rau cov khoom siv tsis ntseeg siab hauv kev txiav txim siab kev ruaj ntseg
