Kungokokuqala sibona a Ukhiye wokuqinisekisa ubunikazi osuselwe ku-FPGA usekelwe kumongo we-RISC-V. Ngokungafani nezinye izindlela ezifana ne-Yubikey, le tokheni yokuvikela ayinakho isitoreji esakhelwe ngaphakathi esiqhubekayo. Njalo uma uxhuma kudivayisi yomsingathi, udinga ukulayisha izinhlelo zokusebenza ku-dongle.
Sebenzisa i-bootstrap ekhethekile yokukhiqiza isihlonzi esiyingqayizivele sohlelo ngalunye, okuyenza ivikeleke kakhulu kunezinye izindlela njengoba okhiye abayimfihlo abagcinwa kudivayisi. Ngaphezu kwalokho, kokubili i-hardware nesofthiwe ye-TKey ingumthombo ovulekile ngokuphelele, oqinisekisa ukwethembeka kwayo uma kuqhathaniswa nezinye izindlela ezivaliwe.
I-Tillitis yinkampani yonogada yaseSweden eyaphuma enkampanini ye-VPN i-Mullvad ngo-2022.. Igama elithi Tillitis liwumdlalo wegama lesiSwidi elithi “tillit,” okusho ukwethembana. Igama elifanele lomkhiqizo osebenza ngokukhethekile emikhiqizweni yokuvikela esekwe kwihadiwe.
Kumele kushiwo ukuthi zikhona izinguqulo ezimbili yethokheni yezokuphepha ye-TKey: ikhiyiwe futhi ayikhiyiwe. I-TKey ekhiyiwe ihloselwe abasebenzisi abajwayelekile futhi ayikwazi ukuhlelwa kabusha. Ngakolunye uhlangothi, i-TKey evuliwe iqondiswe kubasebenzisi abajwayelekile futhi ivumela ukucushwa okuphelele kwe-TKey ngosizo lolunye umshini, umhleli we-Tillitis TK-1 osekelwe ku-Raspberry Pico.
En iwebhusayithi yenkampani ungathola izinhlelo zokusebenza ze-TKey ezimbalwa ezakhelwe ngaphambilini etholakalayo ukuze ilandwe. I-TKey Developer's Manual ihlanganisa ukuthuthukisa idivayisi yakho nezinhlelo zokusebenza zeklayenti ze-TKey. Njengoba kushiwo ngenhla, i-Tillitis' TKey ingumthombo ovuleke ngokuphelele futhi yonke isofthiwe, i-firmware, ikhodi yomthombo we-Verilog, ama-schematics namafayela wokuklama we-PCB angatholakala endaweni yokugcina ye-GitHub.
Izinguqulo zomsebenzisi wokugcina nezithuthukisiwe zokhiye wokuqinisekisa ubunikazi we-TKey RISC-V zingathengwa esitolo se-Tillitis ngo-880 SEK noma i-SEK (ngaphansi nje kuka-€80), kuyilapho umhleli enenani elingu-500 SEK (ngaphansi kwama-€50).
Imininingwane yobuchwepheshe ye-Tillitis Tkey
Ngokuqondene ne izici zobuchwepheshe Kulo khiye omusha wokuphepha wehadiwe, i-Tillitis TKey ihlanganisa:
- I-SoC:
- I-PicoRV32 core esekelwe ku-32-bit RISC-V ISA @ 18 MHz
- I-FPGA: I-Lattice iCE40 UP5K
- 128 KiB RAM yohlelo lokusebenza lwe-TKey
- 2 KB RAM ye-firmware elayishiwe
- 6KiB ROM
- I-Execution Monitor
- Ukuvikelwa kwememori ye-RAM
- Isixhumi sohlobo lwe-USB-C
- Amamodi akhethekile: Imodi ye-firmware nemodi yohlelo
- Abanye: inzwa yokuthinta ye-biometric, inkomba yamandla, inkomba yesimo isebenzisa ama-LED
- Ukudla: 5V @ 100mA
- Ibanga lokushisa elibekezeleleke: 0 ° C - 40 ° C
Uyini ukhiye wokuqinisekisa ubunikazi? Kwenzelweni?
Uma ngabe ubungazi, a Ukhiye wokuqinisekisa ubunikazi we-USB Kuyidivayisi yezingxenyekazi zekhompuyutha enikeza isendlalelo esengeziwe sokuphepha sama-akhawunti akho aku-inthanethi nezinye izikhathi ezidinga imininingwane yokungena. Lawa madivayisi, aziwa nangokuthi "ama-dongles", axhumeka kumadivayisi akho ngembobo ye-USB4, okungukuthi, i-USB-C, ngokuvamile.
Okhiye bokuqinisekisa ubunikazi be-USB basebenza ngokusebenzisa I-U2F, indinganiso yokuqinisekisa enezinyathelo ezimbili. Ngokungafani nokuqinisekiswa okuzinyathelo ezimbili okuvamile, lapho uthola khona ikhodi, enokhiye bokuqinisekisa ubunikazi udinga ukuba nokufinyelela okungokoqobo kudivayisi yehadiwe esebenza njengokhiye. Lawa madivayisi afana nanoma iyiphi inkumbulo ye-USB emakethe, kodwa afakwe i-chip ekhethekile enikeza ukuvikeleka okwengeziwe ngokuqinisekisa kokubili i-akhawunti ne-URL. Lokhu kusiza ukugwema amasu obugebengu bokweba imininingwane ebucayi angaholela ekulingiseni i-akhawunti.
Okhiye bokuqinisekisa ubunikazi be-USB bavikela ama-akhawunti akho aku-inthanethi ngezinga eliphakeme lokuvikela kunaleso elinikezwa yisofthiwe. Futhi, njengamathuluzi aphathekayo, avumela inqubo yokuhlonza eyizinyathelo ezimbili ukuthi isetshenziswe ngaphandle kwesidingo sokusebenzisa ama-imeyili noma izinombolo zocingo ukuze kuqinisekiswe ubuwena, ngaphezu kokudinga lo khiye ukuze ungene. Ngaphandle kokhiye, ngeke ukwazi ukufinyelela i-akhawunti yakho yomsebenzisi...
