Time synchronization

Overview#

Time synchronization is the process that attempts to ensure all systems within a Domain have the same Time

Two primary Operating System Time synchronization Services:

Time synchronization is essential to Internet security as many security protocols and other applications require Time synchronization MCBG (RFC 7384). Unfortunately widely deployed protocols such as the Network Time Protocol (NTP) (RFC 5905) lack essential Security Considerations, and even newer protocols like Network Time Security (NTS) I-D.ietf-ntp-using-nts-for-ntp fail to ensure that the servers behave correctly. Authenticated time servers prevents network adversaries from modifying time packets. An authenticated time server still has full control over the contents of time packet and may go rogue.

Roughtime protocol provides cryptographic proof of malfeasance, enabling clients to detect and prove to a Third-party server's attempts to influence the time a client computes.
