Hi,
I have built an image with deb package support and for authorization of the
incoming packages, i have to transfer a public key to the image and do the
command apt-key add <keyFile>. i do this for the first time the image is
booting but i want to automate the process when i build the image.
i have already created recipe which copy the public key to image rootfs
under /deb_key/keyFile then i tried to perform apt-key command in the image
recipe with

ROOTFS_POSTPROCESS_COMMAND += "addkeyfile;"

So, what the right way to do this ?

You should study how signing RPM/IPK package feeds is done in Yocto, and 
modify the code in the same way. Start from

meta/recipes-core/meta/signing-keys.bb
meta/classes/sign_package_feed.bbclass
meta/lib/oe/package_manager.py (RpmIndexer/OpkgIndexer classes)

Then modify DpkgIndexer class to use apt-key to do the signing in a 
similar way. It even has a stub:

         if self.d.getVar('PACKAGE_FEED_SIGN') == '1':
             raise NotImplementedError('Package feed signing not 
implementd for dpkg')
