EOS 4.35.0F introduces support for Network Time Security (NTS), as defined in RFC8915. NTS provides modern cryptographic security for the client-server mode of the Network Time Protocol (NTP). It separates key establishment from time synchronization by using a TLS-based NTS Key Establishment (NTS-KE) protocol to negotiate symmetric keys and encrypted cookies. These cookies are included in subsequent NTP packets to enable stateless authentication by the server. NTS ensures that time synchronization data is received from a legitimate source and has not been modified in transit.
