V\u011bt\u0161\u00edm probl\u00e9mem by mohla b\u00fdt obrovsk\u00e1 setrva\u010dnost st\u00e1vaj\u00edc\u00ed infrastruktury. Kryptografie je dnes prakticky v\u0161ude: v serverech, routerech, chytr\u00fdch telefonech, pr\u016fmyslov\u00fdch z\u00e1vodech, cloudov\u00fdch platform\u00e1ch, vl\u00e1dn\u00edch s\u00edt\u00edch a milionech star\u0161\u00edch za\u0159\u00edzen\u00ed. Takov\u00e9 syst\u00e9my nelze nahradit b\u011bhem n\u011bkolika m\u011bs\u00edc\u016f. NIST upozor\u0148uje, \u017ee p\u0159edchoz\u00ed kryptografick\u00e9 migrace mohly trvat deset a\u017e dvacet let.<\/span><\/p>\n

To vytv\u00e1\u0159\u00ed paradoxn\u00ed z\u00e1vod: Nikdo nev\u00ed, kdy soupe\u0159 stroj skute\u010dn\u011b z\u00edsk\u00e1 \u2013 ale kdokoli za\u010dne s konverz\u00ed a\u017e pot\u00e9, co existuje, u\u017e mo\u017en\u00e1 prohr\u00e1l.<\/span><\/p>\n

Technicky v tom existuje jen m\u00e1lo mo\u017enost\u00ed, jak tomu zabr\u00e1nit. \u00dalo\u017en\u00fd prostor je levn\u00fd, data lze kop\u00edrovat t\u00e9m\u011b\u0159 neomezen\u011b a hora \u0161ifrovan\u00fdch dat, kter\u00e1 se dnes jev\u00ed jako bezcenn\u00e1, by se v budoucnu mohla n\u00e1hle st\u00e1t voln\u011b dostupn\u00fdm zpravodajsk\u00fdm archivem.<\/span><\/p>\n

Je v\u0161ak t\u0159eba zde jasn\u011b rozli\u0161ovat.
