Compania Google a publicat un set deschis de biblioteci \u0219i utilitare cu implementarea unui sistem de criptare complet omomorf\u0103, care permite procesarea datelor \u00een form\u0103 criptat\u0103, f\u0103r\u0103 ca acestea s\u0103 fie vizibile \u00een format deschis \u00een nicio etap\u0103 a calculului. Instrumentele ofer\u0103 posibilitatea de a crea programe pentru calcul confiden\u021bial, capabile s\u0103 lucreze cu date f\u0103r\u0103 decriptare, inclusiv s\u0103 efectueze opera\u021bii matematice \u0219i simple opera\u021bii pe \u0219iruri de caractere asupra datelor criptate. Codul proiectului este scris \u00een limbajul C++ \u0219i este distribuit sub licen\u021ba Apache 2.0. <\/p>\n

Spre deosebire de criptarea end-to-end, criptarea omomorf\u0103 ofer\u0103, pe l\u00e2ng\u0103 protec\u021bia transmisiei de date, \u0219i posibilitatea de a procesa datele f\u0103r\u0103 a le decripta. Prin omomorfismul complet se \u00een\u021belege capacitatea de a efectua opera\u021bii de adunare \u0219i \u00eenmul\u021bire pe date criptate, pe baza c\u0103rora se pot realiza orice calcule arbitrare. Rezultatul final ob\u021binut este criptat \u0219i ar fi echivalent cu criptarea rezultatului opera\u021biunilor similare asupra datelor originale. <\/p>\n

Lucrul cu datele \u00een criptarea omomorf\u0103 se reduce la faptul c\u0103 utilizatorul cripteaz\u0103 datele \u0219i, f\u0103r\u0103 a dezv\u0103lui cheile, le trimite pentru procesare c\u0103tre un serviciu extern. Acest serviciu efectueaz\u0103 calculele solicitate \u0219i returneaz\u0103 un rezultat criptat, f\u0103r\u0103 a avea capacitatea de a determina cu ce date lucreaz\u0103. Utilizatorul decripteaz\u0103 datele emise cu ajutorul cheilor sale \u0219i ob\u021bine rezultatul \u00een form\u0103 deschis\u0103.

\"Google<\/center> <\/p>\n

Domeniile de aplicare a cript\u0103rii omomorfe includ crearea de servicii cloud pentru calcul confiden\u021bial, implementarea sistemelor de vot electronic, crearea protocoalelor de rutare anonimizate, procesarea solicit\u0103rilor asupra datelor criptate \u00een SGBD-uri, antrenarea confiden\u021bial\u0103 a sistemelor de \u00eenv\u0103\u021bare automat\u0103. <\/p>\n

De exemplu, criptarea omomorf\u0103 se va dovedi util\u0103 \u00een aplica\u021biile medicale, care vor putea ob\u021bine informa\u021bii confiden\u021biale de la pacien\u021bi \u00een form\u0103 criptat\u0103 \u0219i vor oferi profesioni\u0219tilor din domeniul medical posibilitatea de a realiza analize \u0219i de a identifica abateri f\u0103r\u0103 a necesita decriptarea. Criptarea omomorf\u0103 poate ajuta, de asemenea, la desf\u0103\u0219urarea de cercet\u0103ri care examineaz\u0103 leg\u0103tura dintre boli \u0219i anumite muta\u021bii genetice, care necesit\u0103 analiza a mii de probe de informa\u021bii genetice. <\/p>\n

Caracteristica distinctiv\u0103 a instrumentarului publicat este posibilitatea de a crea programe pentru procesarea datelor criptate, folosind tehnici standard de dezvoltare \u00een limbajul C++. Cu ajutorul transpilerului furnizat, programul \u00een C++ este transformat \u00eentr-un dialect special FHE-C++, capabil s\u0103 lucreze cu date criptate.
