F\u00f6retaget Google har publicerat ett \u00f6ppet bibliotek och verktyg med implementationen av ett system f\u00f6r fullst\u00e4ndig homomorfisk kryptering, vilket m\u00f6jligg\u00f6r hantering av data i krypterad form som inte f\u00f6rekommer i \u00f6ppen form under n\u00e5got steg av ber\u00e4kningarna. Verktyget g\u00f6r det m\u00f6jligt att skapa program f\u00f6r konfidentiella ber\u00e4kningar som kan arbeta med data utan avkryptering, inklusive att utf\u00f6ra matematiska och enkla str\u00e4ngoperationer p\u00e5 krypterad data. Projektets kod \u00e4r skriven i C++ och distribueras under Apache 2.0-licensen. <\/p>\n

Till skillnad fr\u00e5n slutna kryptering, erbjuder homomorfisk kryptering f\u00f6rutom skydd av datatransmission m\u00f6jligheten att bearbeta data utan att de avkrypteras. Fullst\u00e4ndig homomorfisitet inneb\u00e4r m\u00f6jligheten att utf\u00f6ra addition och multiplikation av krypterade data, utifr\u00e5n vilka man kan utf\u00f6ra godtyckliga ber\u00e4kningar. Utdata \u00e4r ett krypterat resultat som skulle motsvara krypteringen av resultatet av motsvarande operationer p\u00e5 de ursprungliga data. <\/p>\n

Arbetet med data vid homomorfisk kryptering handlar om att anv\u00e4ndaren krypterar data och utan att avsl\u00f6ja nycklarna skickar dem f\u00f6r bearbetning till en extern tj\u00e4nst. Denna tj\u00e4nst utf\u00f6r de beg\u00e4rda ber\u00e4kningarna och genererar ett krypterat resultat utan m\u00f6jlighet att avg\u00f6ra vilka data den arbetar med. Anv\u00e4ndaren avkrypterar de utgivna data med sina nycklar och f\u00e5r resultatet i \u00f6ppen form.

Inom till\u00e4mpningsomr\u00e5den f\u00f6r homomorfisk kryptering n\u00e4mns skapandet av molntj\u00e4nster f\u00f6r konfidentiella ber\u00e4kningar, implementeringen av system f\u00f6r elektronisk r\u00f6stning, skapandet av anonymiserade routningsprotokoll och hantering av f\u00f6rfr\u00e5gningar p\u00e5 krypterad data i databashanteringssystem, samt konfidentiell tr\u00e4ning av maskininl\u00e4rningssystem. <\/p>\n

Till exempel kan homomorfisk kryptering vara anv\u00e4ndbar inom medicinska till\u00e4mpningar som kan ta emot konfidentiell information fr\u00e5n patienter i krypterad form och ge v\u00e5rdpersonal m\u00f6jlighet att genomf\u00f6ra analyser och uppt\u00e4cka avvikelser utan avkodning. Homomorfisk kryptering kan ocks\u00e5 hj\u00e4lpa till att genomf\u00f6ra forskning som unders\u00f6ker sambandet mellan sjukdomar och vissa genetiska mutationer, d\u00e4r analys av tusentals prover av genetisk information kr\u00e4vs. <\/p>\n

En utm\u00e4rkande egenskap hos det publicerade verktyget \u00e4r m\u00f6jligheten att skapa program f\u00f6r att bearbeta krypterade data, med hj\u00e4lp av standardutvecklingstekniker p\u00e5 C++. Med den tillhandah\u00e5llna transpileraren omvandlas C++-programmet till en speciell dialekt, FHE-C++, som kan arbeta med krypterade data.
