NTP messages authenticated using PKI or a FIPS-approved MAC

Can someone please provide insight into how NTP can be configured to authenticate using PKI or a FIPS-Approved message authentication code algorithm such as SHA-1? The standard MD5 authentication is no longer permitted per a security guideline. Thanks in advance.

James,

At this point there isn't an available solution that Cisco has provided that I am aware of or can find to address this requirement that is approaching a birthday.
