Maererano nezvinobuda munhau, boka revatsvakurudzi vepaUniversity of Michigan kuUnited States nguva pfupi yadarika vakati vakakwanisa kugadzira purosesa yekutanga pasi rose isingabatiki, MORPHEUS.
Iyi nyowani, isingachinjiki processor inogona kuita data encryption mashandiro nekukurumidza zvekuti maalgorithms ayo anochinja nekukurumidza kupfuura anogona kuita zvinopesana nevanobira; Nokudaro, inopa kuchengetedzwa kwakanyanya kudarika nzira dzekudzivirira dzezvino processors.
Sangana neyekutanga pasirese isinga hackable processor
Boka revatsvagiri vepaYunivhesiti yeMichigan kuUS rakati rakagadzira processor yekutanga isingabatike pasi rose, MORPHEUS.
Iyi nyowani, isingachinjiki processor inogona kuita data encryption mashandiro nekukurumidza zvekuti maalgorithms ayo anochinja nekukurumidza kupfuura anogona kuita zvinopesana nevanobira; Nokudaro, inopa kuchengetedzwa kwakanyanya kudarika nzira dzekudzivirira dzezvino processors.
Kana chero chinhu chaigona kumira pachena, gore rapfuura 2018 yaive nhamba huru yekusagadzikana kwakawanikwa muma processors. AMD kunyanya Intel . Zvikanganiso zvinozivikanwa zvakaita seMeltdown, Specter uye, nguva pfupi yadarika, PortSmash neSPOILER zvakaita kuti vaongorori pamakambani maviri aya vapenge mukuyedza kuzvigadzirisa.
Nekudaro, timu yemasayendisiti kubva kuYunivhesiti yeMichigan, inotungamirwa na Todd Austin , dhizaini yake nyowani yema processors, inonzi MORPHEUS, inokwanisa kudzoreredza kurwiswa kune processor yemidziyo yavanoisirwa.
Kune izvi, iyo processor inogona zvachose uye isina kurongeka kushandura mamwe maficha ekuvaka kwayo kuitira kuti vanorwisa vasazomboziva chaizvo zvavari kuyedza kuwana. Asi zvakanyanya kukosha, Morpheus anogona kuita basa nekukurumidza uye nekushomeka kwekushandisa.
Kiyi yekuchengetedzeka ndeyekuti iyo-nyowani-nyowani MORPHEUS processor inoda kupa "maitiro ekupa" kana mamwe mashandiro ekodhi anozivikanwa se "undefined semantics". Ichi chikamu chinongoratidza nzvimbo, saizi, uye zvirimo zvechiratidzo chechirongwa.
Nokudaro, kana munhu anorwisa achida kushandisa iyi data, iyo inowanzogadziriswa, kana chero mamiriro ezvinhu aripo, haazokwanisi kuiwana zvachose, nokuti mushure me50 milliseconds, inenge yachinja kune mamwe maitiro. Iyi kodhi yekuodha patsva mwero wakakwira kakawanda kupfuura Nzira dzemazuva ano uye dzine simba dzekubira inoshandiswa nhasi nema processor azvino.
Iyo MORPHEUS dhizaini, yekujekesa, yakaiswa muRISC-V architecture processor, yakavhurika sosi chip inoshandiswa zvakanyanya mu "prototyping" kusimudzira. Neiyi processor, MORPHEUS yakarwiswa "Kudzora-Kuyerera" Ndiyo imwe yenzira dzine hasha dzaanoshandisa hackers Munyika. Uye akakwanisa kunzvenga zvishwe zvose zvakaurayiwa nekubudirira kwakakwana.
Verenga zvakare: Maitiro ekutarisa kuti processor inogona kumhanya sei
Sezvinotarisirwa, iyo isina simba processor architecture kodhi reshiyo ine mutengo mune system zviwanikwa. Zvisinei, masayendisiti akagadzira MORPHEUS uye anoti mari yekubatsira iyi inongova 1% chete, uye kukurumidza iyo iyo code inova isina kujairika inogona kusiyana, zvichienderana nechinangwa icho processor ichashandiswa.
Izvi zvinosanganisirawo detector yekurwiswa, iyo inoongorora kana imwe inogona kuitika uye nekumhanyisa kubva pane iyi data.
