Projekat je stvoren kao fork referentne implementacije protokola NTPv4 (NTP Classic 4.3.34), fokusiran na redizajn kodne baze radi pove\u0107anja bezbednosti. Izvorni kod NTPsec se distribuira pod licencama BSD, MIT i NTP.    <\/p>\n<p>NTPsec se razvija pod vo\u0111stvom Erika Rejmonda (Eric S. Raymond) uz u\u010destvovanje nekih programera originalnog NTP Classic, in\u017eenjera iz kompanija Hewlett Packard i Akamai Technologies, kao i projekata GPSD i RTEMS. Od razlika u odnosu na NTP Classic isti\u010de se dodavanje podr\u0161ke za protokol NTS (Network Time Security), smanjenje veli\u010dine kodne baze vi\u0161e od dva puta (uklonjene zastarele mogu\u0107nosti i neaktuelne platforme), implementacija re\u017eima autonomnog rada, uklju\u010divanje metoda za spre\u010davanje napada (na primer, filtriranje sistemskih poziva) i prelazak na za\u0161ti\u0107ene funkcije za rad sa memorijom i stringovima.        <\/p>\n<p>U novoj verziji:  <\/p>\n<ul>\n<li class=\"l\"> Dodana je opcija &#171;extra port xxxx&#187; za primanje zahtjeva na dodatnom mre\u017enom portu, uz osnovni port koji se postavlja putem &#171;nts port xxxx&#187;. Dodatni port mo\u017ee biti koristan za zaobila\u017eenje blokada pristupa vanjskim NTP poslu\u017eiteljima koje postavljaju vatrozidi.\n<li class=\"l\"> Dodana je podr\u0161ka za izgradnju na Linux sistemima sa arhitekturom armhf.\n<li class=\"l\"> Obezbe\u0111ena je podr\u0161ka za rad ntpd-a na sistemima u FIPS re\u017eimu.\n<li class=\"l\"> Sustav izgradnje Waf a\u017euriran je na verziju 2.1.4.
