Iri Rekushanda Boka re internet mainjiniya (IETF), inova nebasa rekusimudzira yeInternet protocols uye mapurani, yapedza kuumbwa kweRFC yeNetwork Time Security protocol (NTS) uye yakaburitsa iwo maratidziro ane hukama neinoratidza RFC 8915.
Iyo RFC akagamuchira chinzvimbo che "Standard Pfungwa", mushure meizvozvo basa rinozotanga kupa iyo RFC chinzvimbo cheDrafti Standard, zvinoreva kuti kugadzikana kweprotocol nekufunga zvese zvakataurwa.
NTS mamiriro idanho rakakosha kusimudzira kuchengetedzeka kwemazuva ekubatanidza masevhisi uye chengetedza vashandisi kubva pakurwiswa kunoteedzera iyo NTP server kune iyo mutengi yaanobatanidza.
Kubiridzira kwevanorwisa kuisa nguva isiri iyo kunogona kushandiswa kukanganisa kuchengetedzwa kwemamwe maratidziro ane nguva, seTLS. Semuenzaniso, kushandura iyo nguva kunogona kutungamira mukusanzwisiswa kwedhisheni dhata yezvitupa zveTLS.
Kusvika ikozvino, iyo NTP uye symmetric encryption yematanho ekutaurirana haina kuvimbisa kuti mutengi anopindirana nechinangwa uye kwete neyakaipirwa NTP sevha, uye kiyi yekusimbiswa haina kupararira sezvo yakanyanya kuomesa kumisikidza.
Pakati pemwedzi mishoma yapfuura, takaona vashandisi vazhinji venguva yedu sevhisi, asi vashoma kwazvo vanoshandisa Network Nguva Kuchengetedzwa. Izvi zvinosiya makomputa ari munjodzi yekurwiswa iyo inoteedzera sevha yavanoshandisa kuwana NTP. Chikamu chechinetso kwaive kushomeka kwemadhiemoni eNTP anowanikwa akatsigira NTS. Dambudziko iro ragadziriswa: chrony uye ntpsec zvese zvinotsigira NTS.
NTS inoshandisa yeruzhinji kiyi yezvivakwa zvezvivakwa (PKI) uye inobvumira kushandiswa kweTLS uye Yakavimbiswa Encryption neiyo Yakabatana Dhata (AEAD) kuchengetedza cryptographically kuchengetedza vatengi-server kutaurirana kuburikidza neNetwork Nguva Protocol (NTP).
NTS inosanganisira zvirevo zviviri zvakasiyana: NTS-KE (NTS kiyi kuisirwa kubata kwekutanga kusimbiswa uye kutaurirana kwakakosha pamusoro peTLS) uye NTS-EF (NTS yekuwedzera minda, inoitisa kunyorera uye kuvimbisa nguva yekuenderana nguva).
NTS wedzera minda yakawanda yakawedzerwa kumataneti eNTP uye inochengetera ruzivo rwehurumende rwese chete padivi remutengi nenzira yekufambisa yekuki. Network chiteshi 4460 yakatsaurirwa kubata NTS kubatana.
Nguva ndiyo hwaro hwekuchengetedzeka kune mazhinji emitemo, seTLS, iyo yatinovimba nayo kuchengetedza hupenyu hwedu online. Pasina nguva chaiyo, hapana nzira yekuona kana humbowo hwapera. Kushaikwa kweyakareruka-kushandisa-yakachengeteka nguva protocol kwave kuri dambudziko kune Internet chengetedzo.
Kuitwa kwekutanga kweiyo NTS yakamisikidzwa kwakakurudzirwa mushanduro dzichangobva kuburitswa dzeNTPsec 1.2.0 uye Chrony 4.0.
Chrony inopa yakasarudzika NTP mutengi uye sevha kuitisa iyo inoshandiswa kuyananisa chaiyo nguva pane akasiyana Linux kugoverwa, kusanganisira Fedora, Ubuntu, SUSE / openSUSE, uye RHEL / CentOS.
NTPsec inogadzirwa pasi pehutungamiriri hwaEric S. Raymond uye forogo yekureva kuitiswa kweiyo NTPv4 protocol (NTP Classic 4.3.34), yakanangana nekugadzirisa patsva kodhi yekodhi yekuvandudza chengetedzo (kuchenesa kodhi isingachashandi, nzira dzekudzivirira kupinda mukati uye mabasa akadzivirirwa) inoshanda nendangariro nemaketani).
Pasina NTS kana symmetric kiyi yekusimbiswa, hapana vimbiso yekuti komputa yako iri kutaura NTP kukombuta iwe yaunofunga kuti ndiyo. Symmetric kiyi yekusimbisa inonetsa uye inorwadza kumisikidza, asi kusvika nguva pfupi yadarika ndiyo yega nzira yakachengeteka uye yakaenzana yekumisikidza NTP. NTS inoshandisa iro basa rinopinda muwebhu yeruzhinji kiyi yezvivakwa kuratidza chokwadi maSeva eNTP uye uve nechokwadi chekuti paunogadzira komputa yako kuti utaure na time.cloudflare.com, ndiyo server inowana nguva kubva kwauri.
Kana iwe uchida kuziva zvakawanda nezvazvo, iwe unogona kutarisa iyo ruzivo Mune inotevera chinongedzo.
