NTP Authentication

Hope you all are good. I got the feed from NTP server on my 6500 switch. After that I want that other devices on my network will get feed from my switch after authentication. But other devices on network is getting feed without authentication.

 

6500 Switch Config:

ntp logging
ntp authentication-key 1 md5 xxxxxxxx
ntp authenticate
ntp trusted-key 1
ntp source Vlan264
ntp update-calendar

ntp master
ntp server 82.200.209.236 

 

Router who is getting feed from 6500:

ntp authentication-key 1 md5  xxxxxxxx 7
ntp authenticate
ntp source GigabitEthernet0/0.264
ntp master
ntp server 1.1.1.1 [This select 6500 switch for synchronization, but for authentication it should be [ntp server 1.1.1.1 key 1]. But it won't work]

 

Please guide me if I am making any mistake. The output of router is given below.
