Ukuphepha nokuvikeleka kwe-cyber kuyinkinga ekhulayo emakethe yezimoto. Abakhiqizi bangasebenzisa ukuqinisekiswa ukuqinisekisa kuphela izingxenye eziqinisekiswe nge-OEM kuphela ezixhunywe ngokuphepha ezinhlelweni zemoto, kanye nokunciphisa usongo olukhulayo lokuhlaselwa kwe-malware.
Ama-microcontroller aphephile eza nosayizi, izindleko nezithiyo zesikhathi nokho, kusho uMaxim.
Le nkampani ibanga ubuqiniso bayo be-DS28C40 Deepcover inciphisa kokubili ubunzima bokuklanywa kwesistimu nemizamo yokuthuthukisa ikhodi ehambisanayo. Isiqinisekisi sinqanda ukwebiwa kwezinto ezinenani eliphakeme njengamamojula angaphambili.
Inikeza ukhiye womphakathi / wangasese we-asymmetric ECDSA (ijika le-ECC-P256) namanye ama-algorithms wokuqinisekisa asemqoka akhelwe kwi-IC. I-DS28C40 iza ngephakeji ye-4x3mm TDFN futhi isebenza ngaphezulu kuka -40 kuye ku-125 ° C.
I-IC ifaka ukusekelwa okwakhelwe ngaphakathi kokhiye wokulinganisa okuvikelekile kwe-hash algorithm (SHA-256); ukugcina okuphephile okhiye be-ECDSA ne-SHA-256; imemori engaguquguquki yesikhathi esisodwa ehlelwa izitifiketi zedijithali nedatha yokukhiqiza.
UMaxim uthi i-interface ejwayelekile yomkhakha we-I²C nesoftware ephansi ngaphezulu kohlangothini lwe-Host yenza lula ukuhlanganiswa komklamo kwengxenye.
UTanner Johnson, umhlaziyi omkhulu we-IoT nomxhumanisi wezokuxhuma e-IHS Markit, manje oyingxenye ye-Informa Tech uthi "Noma yibuphi ubuchwepheshe bezokuphepha obususelwa emazingeni athembisa ukuphazamisa ukusetshenziswa kwezakhi ezingaqinisekisiwe futhi okwenza inqubo ibe nezindleko ezengeziwe izodonsa intshisekelo eqinile kubadali."
UMichael Haight, umqondisi, ukuphepha okushumekiwe eMaxim Integrated uthi “Ama-ICs wethu wamuva wokunyathelisa ngezinyawo ezincane asiza [onjiniyela] ukuthi bangeze i-crypto-security esezingeni eliphakeme kakhulu etholakalayo ngaphandle kokungeza amaqembu amasha entuthuko ukuze abhale futhi alungise ikhodi edingeka kakhulu ku-microcontroller naku-software. izindlela ezincikile. ”
