Compania Cloudflare a anun\u021bat crearea unui centru de certificare propriu, destinat oferirii de certificate TLS gratuite, care folosesc algoritmi criptografici rezisten\u021bi la spargere de c\u0103tre calculatoarele cuantice. De asemenea, a fost anun\u021bat\u0103 achizi\u021bia centrului de certificare GlobalSign, care va servi drept baz\u0103 pentru implementarea proiectului propus \u0219i va permite emiterea imediat\u0103 de certificate, pentru care este asigurat un grad maximal de acoperire a dispozitivelor, datorit\u0103 prezen\u021bei GlobalSign \u00een listele existente de certificate de r\u0103d\u0103cin\u0103. \u00cen plus, compania Cloudflare a depus cereri pentru includerea propriului certificat de r\u0103d\u0103cin\u0103 \u00een listele de certificate de r\u0103d\u0103cin\u0103 acceptate de Google, Apple, Microsoft \u0219i Mozilla. <\/p>\n

Se a\u0219teapt\u0103 ca noul certificat public s\u0103 completeze serviciul Let's Encrypt, a c\u0103rui cot\u0103 \u00eentre autorit\u0103\u021bile de certificare este evaluat\u0103 la 39.2% din num\u0103rul certificatelor emise. Leg\u0103tura aproape a jum\u0103tate din site-uri la o singur\u0103 autoritate de certificare creeaz\u0103 riscuri sistemice \u00een cazul defec\u021biunilor de func\u021bionare ale Let's Encrypt din lipsa unor alternative gratuite similare. La fel ca Let's Encrypt, serviciul Cloudflare va fi complet automatizat \u0219i va permite gestionarea certificatelor utiliz\u00e2nd protocolul deschis ACME. Pentru a ob\u021bine un certificat \u00een serviciul Cloudflare, utilizatorii Let's Encrypt trebuie doar s\u0103 schimbe URL-ul \u00een set\u0103ri. <\/p>\n

A doua sarcin\u0103 a noului centru de certificare este preg\u0103tirea pentru tranzi\u021bia la criptografia post-cuantic\u0103. \u00cen primul trimestru din 2027, compania Cloudflare pl\u0103nuie\u0219te s\u0103 fie una dintre primele care va implementa \u00een centrul s\u0103u de certificare suportul pentru formatul simplificat de certificate MTC (Merkle Tree Certificates), destinat utiliz\u0103rii cu algoritmi criptografici post-cuanti, dimensiunea semn\u0103turii digitale fiind de aproximativ 40 de ori mai mare dec\u00e2t cea a semn\u0103turilor tradi\u021bionale. <\/p>\n

Pentru a reduce dimensiunea datelor la fiecare conexiune TLS, \u00een MTC este utilizat\u0103 o structur\u0103 arborescent\u0103 'Arborele Merkle' (Merkle Tree), \u00een care fiecare ramur\u0103 verific\u0103 toate ramurile \u0219i nodurile subiacente, datorit\u0103 hash-\u0103rii comune (arborescente). Dac\u0103 \u00een abordarea tradi\u021bional\u0103 autoritatea de certificare semneaz\u0103 fiecare certificat \u00een parte, \u00een utilizarea MTC, certificatele sunt combinate \u0219i ad\u0103ugate \u00eentr-un jurnal bazat pe arborele Merkle, iar se semneaz\u0103 doar hash-ul r\u0103d\u0103cin\u0103. Cu un astfel de sistem, av\u00e2nd un hash final, se poate confirma c\u0103 un anumit certificat este inclus \u00een arborele semnat curent. La conectarea la site, browserul prime\u0219te un certificat MTC scurtat \u0219i un set de hash-uri pentru dovada matematic\u0103 a includerii sale \u00een arbore, ceea ce permite clientului s\u0103 verifice autenticitatea site-ului pe baza confirm\u0103rii c\u0103 certificatul se afl\u0103 \u00eentr-adev\u0103r \u00een arborele semnat. <\/p>\n

Autoritatea de certificare Cloudflare va suporta at\u00e2t certificate tradi\u021bionale, c\u00e2t \u0219i certificate MTC, ceea ce va permite utilizatorilor s\u0103 treac\u0103 u\u0219or la noul format. Lansarea public\u0103 a proiectului este a\u0219teptat\u0103 dup\u0103 finalizarea test\u0103rii noii infrastructuri pe serviciile interne Cloudflare. Cloudflare se angajeaz\u0103 s\u0103 asigure transparen\u021ba complet\u0103 a proceselor din noua autoritate de certificare, s\u0103 publice versiuni reproduceabile ale software-ului utilizat pentru generarea semn\u0103turilor digitale, s\u0103 efectueze certificarea modulelor hardware de securitate (HSM) \u00een care sunt p\u0103strate cheile private \u0219i s\u0103 dezv\u0103luie rapid informa\u021bii despre probleme \u0219i incidente.
