Chinsinsi chabwino chamtsogolo (PFS) anafotokoza

Perfect forward secrecy (PFS) ndi gawo lachitetezo lomwe limagwiritsidwa ntchito pamakina obisika (mwachitsanzo. VPNconnections) kuteteza deta kuti isasokonezedwe, ngakhale makiyi obisala atalandidwa kapena kuganiziridwa ndi munthu wina wosaloledwa.

PFS zimatheka posintha pafupipafupi makiyi obisa omwe amagwiritsidwa ntchito pobisa. Mwanjira imeneyi, kuchuluka kwa data kokha kumawululidwa ngati munthu wina wosaloledwa agwira makiyi obisa.

Perfect forward secrecy kumawonjezera chitetezo cha VPN- mgwirizano

Chimodzi mwazogwiritsidwa ntchito kwambiri perfect forward secrecy munali VPN- mgwirizano (Virtual Private Network). VPNmaulumikizidwe amathandizira ogwiritsa ntchito kukhazikitsa kulumikizana kotetezeka, kobisika ndi netiweki ina pa intaneti.

Izi zitha kukhala zothandiza kuwonetsetsa kuti deta siyingalandidwe pamene ikufalitsidwa, kapena kulola ogwiritsa ntchito kupeza maukonde omwe sakanatha kuwapeza.

Pamene a VPNkugwirizana kumakhazikitsidwa, makiyi awiri obisala amapangidwa: kiyi yapagulu ndi kiyi yachinsinsi. Makiyi apagulu amagwiritsidwa ntchito kubisa deta yomwe imatumizidwa pa intaneti, pomwe makiyi achinsinsi amagwiritsidwa ntchito kubisa deta ikalandiridwa. Makiyi awa amasinthidwa pakati VPN- kasitomala ndi VPNseva, ndipo amagwiritsidwa ntchito kukhazikitsa kulumikizana kotetezeka, kobisika pakati pa awiriwo.

PFS imagwira ntchito posintha pafupipafupi makiyi omwe amagwiritsidwa ntchito kubisa deta yanu. M'malo mogwiritsa ntchito kiyi yomweyo kubisa zonse zomwe zadutsa VPNkulumikizidwa, kiyi yatsopano, yosakhalitsa imapangidwa kuti isamutsidwe aliyense payekha. Deta ikatumizidwa, imabisidwa ndi kiyi yakanthawi iyi, ndipo wolandirayo amatha kuyilemba ndi kiyi yomweyo.

Mwanjira imeneyi, munthu wina wosaloledwa yemwe wapeza makiyi obisa atha kupeza mwayi wotengera kusamutsa kwa data. Deta ina ikadali yotetezeka chifukwa imasungidwa ndi makiyi ena. makiyi.

VPN-malumikizidwe nthawi zambiri amagwiritsa ntchito makiyi a ephemeral PFS

Pali njira zingapo zomwe zingagwiritsidwe ntchito kukwaniritsa izi perfect forward secrecy i VPN- mgwirizano. Imodzi mwa njira zodziwika kwambiri ndikugwiritsa ntchito makiyi a ephemeral, omwe ndi makiyi osakhalitsa opangidwa pagawo lililonse.

Pamene a VPNkugwirizana kumakhazikitsidwa, kiyi yatsopano ya ephemeral imapangidwa, yomwe imagwiritsidwa ntchito kubisa deta yonse yotumizidwa pa intaneti. Gawoli likatha, fungulo limasiya kukhala lovomerezeka ndipo fungulo latsopano limapangidwa pakugwirizana kotsatira.
