Malinga ndi malipoti aposachedwa, gulu la akatswiri ofufuza a ku yunivesite ya Michigan ku United States posachedwapa lati lidakwanitsa kupanga purosesa yoyamba padziko lonse lapansi yosathyoka, MORPHEUS.
Purosesa yatsopanoyi, yosasunthika imatha kuchita ma encryption a data mwachangu kotero kuti ma aligorivimu ake amasintha mwachangu kuposa momwe obera angachitire; Chifukwa chake, imapereka chitetezo chochulukirapo kuposa njira zodzitetezera za mapurosesa apano.
Kumanani ndi purosesa yoyamba padziko lonse lapansi yosathyoka
Gulu la ofufuza ochokera ku yunivesite ya Michigan ku US akuti adapanga purosesa yoyamba padziko lonse lapansi yosathyoka, MORPHEUS.
Purosesa yatsopanoyi, yosasunthika imatha kuchita ma encryption a data mwachangu kotero kuti ma aligorivimu ake amasintha mwachangu kuposa momwe obera angachitire; Chifukwa chake, imapereka chitetezo chochulukirapo kuposa njira zodzitetezera za mapurosesa apano.
Ngati chilichonse chingawonekere, chaka chatha 2018 chinali chiwerengero chachikulu cha ziwopsezo zazikulu zomwe zidapezeka mu processors. AMD makamaka Intel . Zolakwa zodziwika monga Meltdown, Specter ndi, posachedwa, PortSmash ndi SPOILER zachititsa ofufuza pamakampani awiriwa misala poyesa kuwathetsa.
Komabe, gulu la asayansi ochokera ku yunivesite ya Michigan, motsogozedwa ndi Todd Austin , mapangidwe ake atsopano a mapurosesa, otchedwa MORPHEUS, omwe amatha kulepheretsa kuukira kwa purosesa ya zipangizo zomwe amaziyika.
Pachifukwa ichi, purosesa imatha kusintha mwachisawawa mbali zina zamamangidwe ake kuti owukirawo asadziwe zomwe akuyesera kupeza. Koma chofunikira kwambiri, Morpheus amatha kugwira ntchitoyi mwachangu komanso kugwiritsa ntchito zinthu zochepa.
Chinsinsi chachitetezo ndikuti purosesa yatsopano ya MORPHEUS ikufuna kupereka "njira zoperekera" kapena machitidwe ena a code omwe amadziwika kuti "undefined semantics". Chigawochi chimangosonyeza malo, kukula kwake, ndi zomwe zili pazithunzi za pulogalamuyi.
Chifukwa chake, ngati wowukirayo akufuna kugwiritsa ntchito deta iyi, yomwe nthawi zambiri imakhala yokhazikika, ngati pali vuto lililonse, sangathe kuipeza kwamuyaya, chifukwa pambuyo pa 50 milliseconds, iwo asintha kukhala zikhalidwe zina. Mlingo woyitanitsanso khodiwu ndi wokwera kangapo kuposa Njira zamakono komanso zamphamvu zowonongeka amagwiritsidwa ntchito masiku ano ndi mapurosesa apano.
Zomangamanga za MORPHEUS, momveka bwino, zimayikidwa mu purosesa yomanga ya RISC-V, chipangizo chotseguka chomwe chimagwiritsidwa ntchito kwambiri pakukula kwa "prototyping". Ndi purosesa iyi, MORPHEUS yawukiridwa "Control-Flow" Ndi imodzi mwa njira zaukali kwambiri zomwe amagwiritsa ntchito owononga Mdziko lapansi. Ndipo anatha kuzilambalala malupu onse amene anaphedwa ndi kupambana kwathunthu.
Werengani komanso: Momwe mungayang'anire kuthamanga kwa purosesa
Monga zikuyembekezeredwa, chiŵerengero chofooka cha purosesa yomangamanga chimakhala ndi mtengo muzinthu zamakina. Komabe, asayansi apanga MORPHEUS ndipo amanena kuti mtengo wa chithandizochi ndi 1% yokha, ndipo liwiro limene codeyo imakhala yosasintha imatha kusiyana, malingana ndi cholinga chomwe pulosesa idzagwiritsidwe ntchito.
Izi zikuphatikizanso chowunikira chowunikira, chomwe chimasanthula nthawi yomwe munthu angachitike ndikuthamanga motengera deta iyi.
