Internet Engineering Task Force (IETF), in IPv6, allowed nodes to Auto-configure using neighbour discovery protocol. Neighbour Discovery (ND) and Address auto-configuration mechanisms may be protected with IPSec Authentication Header (AH). Protecting all traffic will include Address Resolution Protocol. To protect this, IPSec will need agreed Key. For Key setup, UDP packet is sent, which requires IPSec for secure communication. So IPSec requires Agreed Key and for Key setup IPSec is needed, this creates a loop. To solve this problem Locally Authentication Process is presented in this paper. This process will provide a certificate of ownership of IP address on network Interface card and Public key to provide authorization. On the other hand, it will also reduce the network load.
