Companiile Google, AMD, NVIDIA \u0219i Microsoft, \u00een cadrul proiectului comun Caliptra, au dezvoltat un bloc de proiectare a circuitelor integrate (IP-block) pentru integrarea \u00een cipuri a unor componente hardware de \u00eencredere (RoT, Root of Trust). Caliptra reprezint\u0103 un bloc hardware separat, cu propria memorie, procesor \u0219i implementare a primitivelor criptografice, asigur\u00e2nd verificarea procesului de \u00eenc\u0103rcare, a firmware-urilor utilizate \u0219i a configura\u021biei dispozitivului stocate \u00een memoria non-volatil\u0103. <\/p>\n

Caliptra poate fi utilizat pentru integrarea \u00een diverse cipuri ale unui bloc hardware independent care realizeaz\u0103 verificarea integrit\u0103\u021bii \u0219i garanteaz\u0103 utilizarea \u00een dispozitiv a firmware-urilor verificate \u0219i autorizate de produc\u0103tor. Caliptra poate simplifica \u0219i uni integrarea mecanismelor hardware \u00eencorporate de verificare criptografic\u0103 \u00een CPU, GPU, SoC, ASIC, adaptoare de re\u021bea, SSD-uri \u0219i alte echipamente. <\/p>\n

Resursele de verificare criptografic\u0103 a integrit\u0103\u021bii \u0219i autenticita\u021bii furnizate de platform\u0103 vor proteja componentele hardware de introducerea modific\u0103rilor mali\u021bioase \u00een firmware-uri \u0219i vor securiza procesul de \u00eenc\u0103rcare \u0219i stocare a configura\u021biei, pentru a preveni compromiterea sistemului de baz\u0103 ca urmare a atacurilor asupra componentelor hardware sau a \u00eenlocuirii modific\u0103rilor mali\u021bioase \u00een lan\u021burile de aprovizionare a cipurilor. \u00cen Caliptra sunt prev\u0103zute, de asemenea, posibilitatea de a verifica autenticitatea actualiz\u0103rilor de firmware \u0219i a datelor asociate platformei (RTU, Root of Trust for Update), detectarea deterior\u0103rii firmware-urilor \u0219i a datelor critice (RTD, Root of Trust for Detection), recuperarea firmware-urilor \u0219i a datelor deteriorate (RTRec, Root of Trust for Recovery). <\/p>\n

Dezvoltarea Caliptra se va desf\u0103\u0219ura \u00een cadrul proiectului comun Open Compute, destinat promov\u0103rii specifica\u021biilor deschise pentru echipamente necesare datacentrelor. Specifica\u021biile legate de Caliptra sunt distribuite sub un acord Open Web Foundation Agreement (OWFa), dezvoltat pentru promovarea standardelor deschise (asem\u0103n\u0103tor cu un licen\u021biat de software open-source pentru specifica\u021bii). Utilizarea OWFa permite crearea de produse \u0219i implement\u0103ri derivate pe baza specifica\u021biei f\u0103r\u0103 plata de redeven\u021be \u0219i permite oric\u0103ror organiza\u021bii s\u0103 participe la dezvoltarea specifica\u021biei. <\/p>\n

Implementarea de baz\u0103 a blocului IP este construit\u0103 pe baza procesorului deschis RISC-V SWeRV EL2 \u0219i este echipat\u0103 cu 384KB RAM (128KB DCCM, 128KB ICCM0 \u0219i 128KB SRAM) \u0219i 32KB ROM. Printre algoritmii criptografici suporta\u021bi se num\u0103r\u0103 SHA256, SHA384, SHA512, ECC Secp384r1, HMAC-DRBG, HMAC SHA384, AES256-ECB, AES256-CBC \u0219i AES256-GCM.
