Andrew Huang (Andrew Huang<\/a><\/noindex>), tuntud avatud riistvara edendaja, kes on p\u00e4lvinud EFF Pioneer Award 2012<\/a><\/noindex>, esitles<\/a><\/noindex> avatud platvorm «Precursor<\/a><\/noindex>«, mis on m\u00f5eldud uute mobiilseadmete kontseptide loomiseks. Sarnaselt sellele, kuidas Raspberry Pi ja Arduino v\u00f5imaldavad luua IoT-seadmeid, on Precursor suunatud v\u00f5imalusele projekteerida ja ise kokku panna erinevaid mobiilseadmeid oma \u00fclesannete lahendamiseks.<\/p>\n

Erinevalt teistest projektidest, Precursor pakub entusiastidele mitte ainult tr\u00fckkplaati, vaid valmistehtud protot\u00fc\u00fcpi kaasaskantavast seadmest alumiiniumkorpuses, mille m\u00f5\u00f5tmed on 69 x 138 x 7.2 mm, LCD-ekraan (336×536), aku (1100 mAh Li-Ion), miniatuurne klaviatuur, k\u00f5lari, vibratsiooni mootori, kiirendi ja g\u00fcroskoop. Arvutusmoodul ei ole varustatud valmis protsessoriga, vaid programmeeritava SoC'iga FPGA Xilinx XC7S50, mille baasil on korraldatud 32-bitise RISC-V CPU emulatsioon, mis t\u00f6\u00f6tab sagedusel 100MHz. Selle juures ei ole mingeid piiranguid teiste riistvara komponentide emuleerimiseks, n\u00e4iteks v\u00f5ib emuleerida erinevate protsessorite t\u00f6\u00f6d, alates 6502 ja Z-80 kuni AVR ja ARM, samuti heliklipse ja erinevaid kontrollerid. Plaat sisaldab 16 MB SRAM, 128 MB Flash, Wi-Fi Silicon Labs WF200C, USB type C, SPI, I\u00b2C, GPIO.<\/p>\n

Turvalisusega seotud v\u00f5imalustest tasub m\u00e4rkida kahe riistvaralise pseudojuhuslike arvude generaatori olemasolu. Huvi tekitav on see, et seade tuleb p\u00f5him\u00f5tteliselt ilma sisseehitatud mikrofonita \u2014 eeldatakse, et heli vastuv\u00f5tt on v\u00f5imalik ainult siis, kui peakomplekt on selges\u00f5naliselt \u00fchendatud, ja kui peakomplekt on lahti \u00fchendatud, on f\u00fc\u00fcsiliselt v\u00f5imatu korraldada pealtkuulamisi, isegi kui seadme tarkvara on kompromiteeritud. <\/p>\n

Traadita sidekiip (Wi-Fi) on riistvaraliselt eraldatud \u00fclej\u00e4\u00e4nud platvormist ja t\u00f6\u00f6tab eraldi keskkonnas. Kahtlase juurdep\u00e4\u00e4su t\u00f5kestamiseks kasutatakse lukustatavat korpust, eraldi RTC-d terviklikkuse j\u00e4lgimiseks ning liikumise j\u00e4lgimist ootere\u017eiimis (alati aktiivsed akseleromeeter ja g\u00fcroskoop). Samuti on olemas eneseregeneratsiooni ahel ja viivitamatu andmete kustutamine, mis aktiveeritakse AES-v\u00f5tme abil.<\/p>\n

Riistvarakomponentide kirjeldamiseks kasutatakse FHDL-keelt Migen<\/a><\/noindex> (Fragmented Hardware Description Language), mis p\u00f5hineb Pythoni peal. Migen kuulub raamistikku LiteX<\/a><\/noindex>, mis pakub infrastruktuuri elektrooniliste skeemide loomiseks. Precursori alusel on FPGA ja LiteX abil valmistatud referentse SoC Betrusted<\/a><\/noindex>, sisaldab 100 MHz CPU VexRISC-V RV32IMAC, samuti sisseehitatud kontrolleri
\nBetrusted-EC, millel on 18 MHz LiteX VexRISC-V RV32I tuum.

SoC Betrusted sisaldab sisseehitatud komplekti kr\u00fcptograafilisi primitiive, nagu pseudojuhuslike numbrite generaator, AES-128, -192, -256 ECB, CBC ja CTR re\u017eiimidega, SHA-2 ja SHA-512, kr\u00fcptomootor<\/a><\/noindex> elliptsete k\u00e4\u00e4rid Curve25519 baasil. Kr\u00fcptomootor on kirjutatud SystemVerilog'is ja p\u00f5hineb kr\u00fcpto tuumadel projektist Google OpenTitan<\/a><\/noindex>. <\/p>\n

Precursor positsioneeritakse protot\u00fc\u00fcpimise ja valideerimise platvormina, samas kui Betrusted on \u00fcks valmis mobiilseadmest, mis on loodud Precursori baasil. Kuna traditsioonilised enklaavid, mida kasutatakse kr\u00fcptov\u00f5tmete isoleeritud salvestamiseks, ei kaitse k\u00f5rgemate r\u00fcnnakute, nagu paroolide kogumine klahvivajutuste kaudu v\u00f5i juurdep\u00e4\u00e4s teadetele ekraanipiltide loomise kaudu, eest, on Betrustedi enklaavi realiseerimisse lisatud elemente, mis v\u00f5imaldavad kasutaja interaktsiooni (HCI<\/a><\/noindex>, Inimese ja arvuti interaktsioon), tagades, et saladusi, mida inimene v\u00f5ib lugeda, ei salvestata, kuvata ega edastata v\u00e4ljaspool kaitstud seadet. <\/p>\n

Betrusted ei \u00fcrita asendada mobiiltelefoni, vaid loob kaitstud enklaavi, mille sisend ja v\u00e4ljund on auditeeritavad. N\u00e4iteks saab v\u00e4list nutitelefoni kasutada Wi-Fi kaudu usaldamatuna andmeedastuskanalina, kuid edastatavad salastatud s\u00f5numid sisestatakse ainult Betrusted seadme sisseehitatud klaviatuuril ning saadetud s\u00f5numid kuvatakse ainult seadme sisseehitatud ekraanil.<\/p>\n

Kogu Precursor ja Betrusted komponendid on avatud ja saadaval modifitseerimiseks ja katsetamiseks Ava riistvara litsents 1.2<\/a><\/noindex>, mis n\u00f5uab, et k\u00f5ik tuletatud teosed avalikustatakse samade tingimustega. Samuti on avatud skeemid<\/a><\/noindex> ja t\u00e4ielik projektdokumentatsioon peamise ja abiploki<\/a><\/noindex>, valmisehitatud SoC Betrusted<\/a><\/noindex> ja kontrolleri<\/a><\/noindex> (EC<\/a><\/noindex>). Saadaval on 3D-printimise korpuse mudelid. Avatud projektide vormis arendatakse ka firmav\u00f5tete komplekti<\/a><\/noindex> ja spetsialiseeritud operatsioonis\u00fcsteem<\/a><\/noindex> Xous mikrokernelil.<\/p>\n
