lowRISC, oo ah urur aan faa'iido doon ahayn oo kormeeraya horumarinta microprocessor lacag la'aan ah oo ku salaysan qaab dhismeedka RISC-V, ayaa ku dhawaaqay helitaanka qalabkii ugu horreeyay ee ganacsi ahaan diyaar u ah oo lagu dhisay madal furan ee OpenTitan, oo loo sameeyay mashruuc wadajir ah oo madaxbannaan. Mashruucan waxaa markii hore aasaasay Google, laakiin ka dib wareejinta lowRISC ee ururka, shirkadaha sida Western Digital, Seagate, Nuvoton Technology, Winbond, Rivos, zeroRISC iyo G+D Mobile Security ayaa ku biiray horumarkeeda. Tilmaamaha koodhka iyo qalabka la xidhiidha mashruuca waxa lagu daabacay shatiga Apache 2.0.
Si ka duwan hirgelinta Root of Trust ee hadda jirta, OpenTitan waxaa loo sameynayaa iyadoo la raacayo fikradda "ammaanka iyada oo loo marayo hufnaanta", taas oo tilmaamaysa helitaanka koodka iyo jaantusyada, iyo sidoo kale geeddi-socod horumarineed oo gebi ahaanba furan, oo aan ku xirnayn iibiyayaal gaar ah ama soosaarayaasha jajabka. Xalalka loo isticmaalo OpenTitan waxay ku salaysan yihiin teknoolojiyada horey loogu isticmaalay calaamadaha USB-ga ee Google Titan iyo jajabyada TPM ee kabaha la xaqiijiyay ee lagu rakibay. adeegayaal kaabayaasha Google, iyo sidoo kale aaladaha Chromebook iyo Pixel.
OpenTitan waa Root of Trust (ROT) madal la istcimaali karo halka hufnaanta qalabka nidaamka iyo walxaha software loo baahan yahay in la hubiyo, iyadoo la hubinayo in qaybaha muhiimka ah ee nidaamka aan la faragelin oo ay ku saleysan yihiin kood soo saaraha oo la xaqiijiyay iyo la oggolaaday. . Mashruucu wuxuu bixiyaa qaab diyaarsan, la xaqiijiyay oo la isku halayn karo kaas oo kuu ogolaanaya inaad kordhiso kalsoonida xalalka la abuurayo oo aad hoos u dhigto kharashyada marka aad horumarinayso jajabyada amniga ee gaarka ah.
Chips-yada ku saleysan OpenTitan waxaa loo isticmaali karaa Motherboard-yada server-ka, kaararka shabakada, aaladaha macaamiisha, router-yada, aaladaha Internetka ee Waxyaabaha si loo xaqiijiyo firmware-ka iyo qaybaha bootable-ka ah, iyo sidoo kale in lagu soo saaro tilmaamo nidaam gaar ah oo cryptographically (ka ilaalinta beddelka qalabka), ilaalinta furayaasha cryptographic ( go'doominta muhiimka ah haddii ay dhacdo in weeraryahanku uu helo helitaanka jirka ee qalabka), bixinta adeegyo la xiriira amniga iyo ilaalinta diiwaanka hanti dhowrka oo go'doonsan oo aan la tafatirin karin ama la tirtiri karin.
OpenTitan waxaa ku jira baloogyo macquul ah oo kala duwan oo looga baahan yahay chips-ka RoT, sida microprocessor furan oo ku saleysan qaab dhismeedka RISC-V (RV32IMCB Ibex), coprocessors cryptographic, koronto-dhaliye nambarka qalabka, maamule muhiim ah oo leh taageerada DICE, hab lagu kaydiyo xogta sugan Joogtada iyo RAM, tignoolajiyada amniga, I/O blocks, aaladaha boot ee sugan, iwm. Qalabku waxa kale oo uu bixiyaa baloogyada hirgeliya algorithms-ka sireed ee caadiga ah, sida AES iyo HMAC-SHA256, iyo dardargeliyaha xisaabta ee loo isticmaalo algorithms-yada saxeexa dhijitaalka ah ee furaha dadweynaha, sida RSA iyo algorithms curve elliptic.
