Network Time Security
Network Time Security (NTS) provides cryptographic security for the client-server mode of the Network Time Protocol (NTP). This allows users to obtain time in an authenticated manner.
The NTS protocol is divided into two phases:
- NTS key exchange: Establishes the necessary key material between the NTP client and the server, using a (the same public key infrastructure as the web). Once the keys are exchanged, the TLS channel is closed and the protocol enters the second phase.
- NTP authentication: Authenticates NTP time syncronization packets using the results of the TLS handshake. For more information, refer to .
If you would like to hear about the development of additional clients or updates on our service or would like to announce that your client supports NTS, send an email
