OpenSSL txhawb nqa kev zais cia siv elliptic nkhaus Diffie-Hellman txij li version 1.0, nrog rau kev suav nyiaj siv ua haujlwm ntawm kwv yees li 15% rau thawj zaug tuav tes. Txoj Cai Teeb Meem siv ob npaug Ratchet Algorithm los muab kev zais cia rau pem hauv ntej.
Hais txog qhov no, kuv yuav ua li cas thiaj li tso cai rau kev zais cia?
Txhawm rau teeb tsa Apache rau Forward Secrecy, koj teeb tsa tus neeg rau zaub mov kom nquag xaiv cipher suites thiab tom qab ntawd qhib txoj cai OpenSSL cipher suite txoj hlua teeb tsa
- Nrhiav koj tus SSL Protocol Configuration ntawm koj Apache server.
- Ntxiv cov kab hauv qab no rau koj qhov kev teeb tsa:
- Rov pib Apache.
Kuj Paub, puas RSA muab kev zais cia rau pem hauv ntej? Tam sim no versions ntawm TLS muab ob hom kev sib pauv tseem ceeb, RSA kev sib pauv tseem ceeb nrog qhov tsis zoo no, thiab Diffie Hellman qhov kev sib pauv tseem ceeb uas muab rau pem hauv ntej secrecy . Lub tom ntej TLS 1.3 specifications poob tag RSA pauv qhov tseem ceeb, ua TLS ib txwm pem hauv ntej ruaj ntseg.
Nyob rau hauv txoj kev no, yuav ua li cas rau pem hauv ntej secrecy ua hauj lwm?
Zoo meej kev zais cia rau pem hauv ntej txhais tau hais tias ib qho ntawm cov txheej txheem encryption tau txais thiab nquag hloov cov yuam sij uas nws siv los encrypt thiab decrypt cov ntaub ntawv, xws li yog tias tus yuam sij tshiab raug cuam tshuam, nws tsuas yog nthuav tawm ib feem me me ntawm tus neeg siv cov ntaub ntawv rhiab heev.
Dab tsi yog qhov zoo meej rau pem hauv ntej secrecy hauv ipsec?
Hauv cryptography, kev zais cia rau pem hauv ntej (tseem hu ua zoo meej rau pem hauv ntej secrecy los yog PFS) yog cov cuab yeej ntawm cov ntawv cog lus tseem ceeb ua kom ntseeg tau tias qhov kev sib tham tseem ceeb tau los ntawm cov yuam sij mus sij hawm ntev tsis tuaj yeem cuam tshuam yog tias ib qho ntawm cov yuam sij mus sij hawm ntev raug cuam tshuam rau yav tom ntej.

Koj txhais li cas los ntawm kev tsis ncaj ncees rau pem hauv ntej thiab thim rov qab ntawm pn junction diode?
Junction Diode Symbol thiab Static I-VCharacteristics Ntawm qhov voltage axis saum toj no, "ReverseBias" yog hais txog ib qho hluav taws xob sab nraud uas ua rau muaj peev xwm thaiv tau. Ib qho hluav taws xob sab nraud uas txo qhov muaj peev xwm cuam tshuam tau hais tias ua raws li "Forward Bias" kev taw qhia
