Greetings of the day,
I have implemented Ntpv4 with symmetric in our hardware. Where my application
code will act as Ntp-server.
When I sent synchronization request from linux pc(Ntp-client::using ntpd
services) without key , client is synchronizing properly.
But when I sending ntp packet with symmetric key, client is not synchronizing.
The hmac md5 digest which is generated by the client is not matching with the
calculated digest from server side.
I have evaluated my hmac-md5 code by giving the all test cases(rfc2202) as per
the rfc. And all the digest were matched.
But it is not matching with the clients ntp packet message digest.
Please suggest some solution for the above issue.
Thanks & Regards
Sukanya Kamakolanu
