Razvijalci Ubuntu Linux so napovedali prehod na projekt Chrony kot privzeto re\u0161itev za sinhronizacijo natan\u010dnega \u010dasa v vseh razli\u010dicah Ubuntu 25.10. Prej je Ubuntu uporabljal storitev systemd-timesyncd, ki jo bodo zamenjali, ker \u017eelijo vklju\u010diti protokol NTS (Network Time Security) za kriptografsko za\u0161\u010dito sinhronizacije \u010dasa. <\/p>\n
Projekt Chrony ponuja neodvisno implementacijo NTP odjemalca in stre\u017enika, ki se \u017ee uporablja za sinhronizacijo natan\u010dnega \u010dasa v Fedora, SUSE\/openSUSE in RHEL. NTS zagotavlja, da se odjemalec povezuje s ciljnim, ne pa z ma\u0161iranim NTP stre\u017enikom. Ponarejanje NTP stre\u017enika predstavlja tveganje, saj lahko napa\u010den \u010das povzro\u010di varnostne te\u017eave pri drugih \u010dasovnih protokolih, kot so TLS in DNSSEC. Sprememba \u010dasa lahko vodi do napa\u010dne razlage podatkov o delovanju certifikatov. <\/p>\n
Protokol NTS uporablja elemente infrastrukture odprtih klju\u010dev (PKI) za vzpostavitev \u0161ifriranega komunikacijskega kanala in omogo\u010da uporabo TLS ter avtorizirane \u0161ifrirane AEAD (Authenticated Encryption with Associated Data) za za\u0161\u010dito uporabnikov pred napadi, ki posnemajo NTP stre\u017enik. NTS vklju\u010duje dva lo\u010dena protokola: NTS-KE (NTS Key Establishment), ki se uporablja za za\u010detno avtorizacijo in usklajevanje klju\u010dev prek TLS, in NTS-EF (NTS Extension Fields), ki je odgovoren za \u0161ifriranje ter avtorizacijo seje sinhronizacije \u010dasa. NTS dodaja ve\u010d raz\u0161irjenih polj v NTP pakete in shranjuje vse informacije o stanju samo na strani odjemalca, pri \u010demer uporablja mehanizem prenosa pi\u0161kotkov. Za obdelavo povezav preko protokola NTS se uporablja omre\u017eni port 4460. <\/p>\n
