Ipak, implementacija ostaje fragmentarna i nepotpuna. Google isti\u010de dvije glavne opasnosti: trenutni napad \"sa\u010duvaj sada\u2014de\u0161ifriraj kasnije\" za \u0161ifrirane podatke i budu\u0107u prijetnju za digitalne potpise. Upravo zato kompanija prioritetno prebacuje svoje sustave autentifikacije, uklju\u010duju\u0107i Android, na PQC.<\/p>\n<p>Kompanija poziva sve in\u017eenjerske timove da slijede njen primjer i ubrzaju migraciju na postkvantnu kriptografiju. Prema njenom mi\u0161ljenju, samo koordinirane akcije industrije mogu sprije\u010diti kriptografski apokalipsu i o\u010duvati sigurnost interneta u eri kvantnog ra\u010dunanja. Zanimljivo je da se vlasti SAD-a, a posebno NSA, pripremaju do\u010dekati \"Dan Q\" ne prije 2031. godine, a vjerojatnije nakon 2033. godine. Od \u010dega je Google uklju\u010dio re\u017eim panike, mo\u017ee se samo naslutiti. Dok stru\u010dnjaci poku\u0161avaju shvatiti upozorenje kompanije, programeri o\u010dekuju pove\u0107anje optere\u0107enja vezano uz hitnu implementaciju novih sigurnosnih protokola u potpisima i
