Esi sisihlandlo sokuqala sibona a Isitshixo sokhuseleko esekwe kwiFPGA sisekwe kundoqo weRISC-V. Ngokungafaniyo nezinye iindlela ezifana neYubikey, olu phawu lokhuseleko alunandawo yokugcina ethe gqolo eyakhelweyo. Ngalo lonke ixesha uqhagamshela kwisixhobo sokusingatha, kufuneka ulayishe ii-apps kwi-dongle.
Sebenzisa i-bootstrap ekhethekileyo ukuvelisa isichongi esisodwa kwisicelo ngasinye, iyenza ikhuseleke ngakumbi kunezinye njengoko izitshixo zabucala zingagcinwanga kwisixhobo. Ukongeza, zombini i-hardware kunye nesoftware ye-TKey yimithombo evuleleke ngokupheleleyo, iqinisekisa ukuthembeka kwayo xa kuthelekiswa nezinye iindlela ezivaliweyo.
I-Tillitis yinkampani yokhuseleko yaseSweden eyaphuma kwinkampani ye-VPN iMullvad ngo-2022.. Igama elithi Tillitis ngumdlalo okwigama lesiSwedish elithi “tillit,” elithetha ukuthembela. Ligama elifanelekileyo lophawu olusebenza kwiimveliso zokhuseleko ezisekwe kwihardware.
Kufuneka kuthiwe kukho ezimbini iinguqulelo ye TKey ithokheni yokhuseleko: itshixiwe yavulwa. I-TKey etshixiweyo yenzelwe abasebenzisi ngokubanzi kwaye ayinakuphinda ihlelwe kwakhona. Ngakolunye uhlangothi, i-TKey evuliwe ijoliswe kubasebenzisi ngokubanzi kwaye ivumela uqwalaselo olupheleleyo lwe-TKey ngoncedo lwesinye isixhobo, umdwelisi we-Tillitis TK-1 esekelwe kwi-Raspberry Pico.
En iwebhusayithi yenkampani ungafumana usetyenziso lwe-TKey olwakhiwe kwangaphambili ekhoyo ukukhuphela. Incwadi ye-TKey Developer's Manual igubungela ukuphuhlisa isixhobo sakho kunye nezicelo zomthengi ze-TKey. Njengoko kukhankanyiwe ngasentla, i-Tillitis 'TKey ingumthombo ovuleleke ngokupheleleyo kunye nayo yonke isoftware, i-firmware, ikhowudi yomthombo weVerilog, ischematics kunye neefayile zoyilo zePCB zinokufumaneka kwindawo yokugcina yeGitHub.
Umsebenzisi wokugqibela kunye neenguqulelo eziphambili ze-TKey RISC-V isitshixo sokhuseleko zingathengwa kwivenkile ye-Tillitis ye-880 SEK okanye i-SEK (ngaphantsi kwe-80 € nje), ngelixa umdwebi wenkqubo uxabisa kwi-500 SEK (ngaphantsi kwe-50 €).
Iinkcukacha zobugcisa zeTillitis Tkey
Ngokuphathelele Iimpawu zobugcisa Kweli qhosha litsha lokhuseleko, iTillitis TKey ibandakanya:
- SoC:
- PicoRV32 core esekelwe 32-bit RISC-V ISA @ 18 MHz
- I-FPGA: I-Lattice iCE40 UP5K
- I-128 KB RAM ye-TKey app
- I-2 KB RAM ye-firmware elayishiwe
- 6 KB yeROM
- Monitor uMiselo
- Ukhuseleko lwenkumbulo ye-RAM
- I-USB-C yohlobo lwesidibanisi
- Iimowudi ezikhethekileyo: imo ye-firmware kunye nemo yesicelo
- Abanye: i-biometric touch sensor, isalathisi samandla, isalathisi sesimo sisebenzisa ii-LEDs
- Ukutya: 5V @ 100mA
- Uluhlu lobushushu obunyamezelekayo: 0 ° C - 40 ° C
Yintoni isitshixo sokhuseleko? Yenzelwe ntoni?
Ukuba ubungazi, a Iqhosha lokhuseleko le-USB Sisixhobo sehardware esinika umaleko owongezelelweyo wokhuseleko kwiiakhawunti zakho ze-intanethi kunye nezinye iiseshini ezifuna iinkcukacha zokungena. Ezi zixhobo, ezikwabizwa ngokuba yi "dongles", qhagamshela kwizixhobo zakho nge-USB4 port, oko kukuthi, i-USB-C, ngokubanzi.
Izitshixo zokhuseleko ze-USB zisebenza ngokusetyenziswa U2F, umgangatho wokuqinisekisa onamanyathelo amabini. Ngokungafaniyo nokuqinisekiswa kwamanyathelo amabini endabuko, apho ufumana ikhowudi, kunye nezitshixo zokhuseleko kufuneka ube nokufikelela ngokomzimba kwisixhobo se-hardware esisebenza njengesitshixo. Ezi zixhobo zifana nayiphi na imemori ye-USB kwimarike, kodwa zixhotyiswe nge-chip ekhethekileyo enikezela ukhuseleko olongezelelweyo ngokuqinisekisa zombini i-akhawunti kunye ne-URL. Oku kunceda ukunqanda ubuchwephesha obunokukhokelela ekulinganisweni kweakhawunti.
Izitshixo zokhuseleko ze-USB zikhusela iiakhawunti zakho ze-intanethi ngeqondo eliphezulu lokhuseleko kunesoftwe ebonelela ngayo. Kwaye, ukuba zizixhobo eziphathekayo, zivumela inkqubo yokuchonga amanyathelo amabini ukuba isetyenziswe ngaphandle kwesidingo sokusebenzisa ii-imeyile okanye iinombolo zefowuni ukuqinisekisa ubuni bakho, ngaphezu kokufuna eli qhosha lokungena. Ngaphandle kwesitshixo, awuzukwazi ukufikelela kwiakhawunti yakho yomsebenzisi...
