NTP authentication begins with the creation of the first NTP packet after key configuration. NTP authentication uses the message digest 5 (MD5) algorithm. The key is embedded in the synchronization packet that is sent to an NTP time source. 1 Enable NTP authentication in CONFIGURATION mode. ntp authenticate 2 Set an authentication key number and key in CONFIGURATION mode (1 to 4294967295). ntp authentication-key number md5 key • The number must match in the ntp trusted-key command. • The key is an encrypted string. 3 Define a trusted key in CONFIGURATION mode (1 to 4294967295).
