Zhvilluesit e Ubuntu Linux kan\u00eb planifikuar kalimin standard n\u00eb p\u00ebrdorimin e projektit Chrony p\u00ebr sinkronizimin e sakt\u00eb t\u00eb koh\u00ebs n\u00eb t\u00eb gjitha versionet e Ubuntu 25.10. M\u00eb par\u00eb, n\u00eb Ubuntu p\u00ebrdorej sh\u00ebrbimi systemd-timesyncd, i cili do t\u00eb z\u00ebvend\u00ebsohet p\u00ebr shkak t\u00eb d\u00ebshir\u00ebs p\u00ebr t\u00eb aktivizuar protokollin NTS (Network Time Security) p\u00ebr mbrojtjen kriptografike t\u00eb sinkronizimit t\u00eb koh\u00ebs. <\/p>\n
Projekti Chrony ofron nj\u00eb implementim t\u00eb pavarur t\u00eb klientit dhe serverit NTP, i cili tashm\u00eb p\u00ebrdoret p\u00ebr sinkronizimin e sakt\u00eb t\u00eb koh\u00ebs n\u00eb Fedora, SUSE\/openSUSE dhe RHEL. NTS garanton q\u00eb klienti t\u00eb nd\u00ebrveproj\u00eb me serverin NTP t\u00eb synuar dhe jo me nj\u00eb server NTP t\u00eb manipuluar. Manipulimi i serverit NTP paraqet rrezik, pasi vendosja e nj\u00eb kohe t\u00eb gabuar mund t\u00eb p\u00ebrdoret p\u00ebr t\u00eb shkelur sigurin\u00eb e protokolleve t\u00eb tjera q\u00eb kan\u00eb t\u00eb b\u00ebjn\u00eb me koh\u00ebn, si\u00e7 jan\u00eb TLS dhe DNSSEC. Ndryshimi i koh\u00ebs mund t\u00eb \u00e7oj\u00eb n\u00eb interpretimin e gabuar t\u00eb t\u00eb dh\u00ebnave mbi veprimet e certifikatave. <\/p>\n

NTS p\u00ebrfshin dy protokolle t\u00eb ve\u00e7anta: NTS-KE (NTS Key Establishment), e cila p\u00ebrdoret p\u00ebr trajtimin e autentifikimit fillestar dhe negociat\u00ebn e \u00e7el\u00ebsave mbi TLS, dhe NTS-EF (NTS Extension Fields), i cili \u00ebsht\u00eb p\u00ebrgjegj\u00ebs p\u00ebr enkriptimin dhe autentifikimin e sesionit t\u00eb sinkronizimit t\u00eb koh\u00ebs. NTS shton disa fusha t\u00eb zgjeruara n\u00eb paketat NTP dhe ruan t\u00eb gjitha informacionet e gjendjes vet\u00ebm n\u00eb an\u00ebn e klientit, duke p\u00ebrdorur mekanizmin e transmetimit cookie. P\u00ebr t\u00eb trajtuar lidhjet p\u00ebrmes protokollit NTS, p\u00ebrdoret porta rrjet 4460. <\/p>\n
