Demiin Miller (djm @) lisatud<\/a><\/noindex> OpenSSH-s on t\u00e4iendus, mis peaks aitama kaitsta erinevate r\u00fcnnakute eest k\u00f5rvalkanalitest, nagu Spectre, Meltdown<\/a><\/noindex>, RowHammer<\/a><\/noindex> ja RAMBleed<\/a><\/noindex>. Lisatud kaitse on m\u00f5eldud selleks, et ennetada privaatv\u00f5tme taastamist, mis on m\u00e4lus, kasutades k\u00f5rvalkanalite andmelekke.<\/p>\n

Kaitse p\u00f5hiolemus seisneb selles, et privaatv\u00f5tmed, kui neid ei kasutata, kr\u00fcpteeritakse s\u00fcmmeetrilise v\u00f5tmega, mis on saadud suhteliselt suurest \"eelv\u00f5tmest\" (prekey), mis koosneb juhuslikest andmetest (praegu on selle suurus 16 KB).
\nRakendamise seisukohalt kr\u00fcpteeritakse privaatv\u00f5tmed m\u00e4llu laadides ja siis automaatselt ja l\u00e4bipaistvalt dekr\u00fcpteeritakse, kui neid kasutatakse allkirjade jaoks v\u00f5i salvestamise\/siserialiseerimise ajal.<\/p>\n

Eduka r\u00fcnnaku jaoks peavad pahatahtlikud isikud taastama kogu prekey'i suure t\u00e4psusega, enne kui nad saavad proovida dekr\u00fcpteerida kaitstud privaatv\u00f5tme. Kuid praeguste r\u00fcnnakute p\u00f5lvkonnal on selline bitide taastamise vigade sagedus, et nende vigade kogum muudab \u00f5ige eelv\u00f5tme taastamise ebat\u00f5en\u00e4oliseks.<\/p>\n
