Can i use microsoft certification services for the same. Regarads,Y iguchi

Sorry no one has responded to this, but the answer is "yes" you can do this. The Microsoft certification authority can produce certificates for any type of client that will accept certificates. You do have a lot to learn and you should probably start with the MSDN materials: http://msdn.microsoft.com/en-us/library/ms731899.aspx
