Followup: 

I forgot to mention that what are CGA parameters (that is really important)

The most important parameter is public key. So CGA uses the hash of public
key and after some conditions and settings, set the CGA value as a 64
rightmost bits of an IPv6 address

IIPv6= Subnetprefix + cga value

So, this makes a binding between the IP address and the public key.
