secure zone transfer and dynamic update

[saravanan ganapathy]

Hai,
  I have configured bind9.2 on my debian woody.TSIG
also configured for zone Txfr and ddns update.

My config file as

zone "abc.com" {
        type master;
        file "abc";
        allow-transfer {key abc.com;};
        allow-update { key abc.com;};
};
server 50.50.50.1 {
   keys { abc.com ;};
   };
key "abc.com." {
        algorithm HMAC-MD5;
        secret "aasfsv131414";
      };

I also configured slave server with this TSIG.It works
well.
 
My Problem:
------------
The master server gives the zone data to any server
which have the same TSIG key, though I have specified
the slave server ip address only in the master server.

The server should responds for zone txfr only when
both the ip address and TSIG key matches.

How to configure this?

I have the same problem with ddns update also.

Pls guide me

Note :

Even " allow-transfer {key abc.com;50.50.50.1;}; "
doesn't help
