IPv6 Addressing Scheme with a Secured Duplicate Address Detection

ABSTRACT

In the IoT network, each node should have the self-configuration capability as well as a unique identifier such as IPv6. The unique IPv6 identity of nodes is primarily maintained by employing the stateless auto-configuration method and Duplicate Address Detection (DAD) protocol. In the existing DAD solutions, when a new node creates a target IPv6 address, it broadcasts a full or partial target address across the network to verify uniqueness. In this process, when the entire target address is broadcast, the target address is exposed to all the nodes of the network, whereas in partial broadcasts, the address of some nodes of the network is exposed to the new node. A malicious node can take advantage of this feature and can disrupt the DAD process by claiming the target address or by making the existing address as assigned. To protect the DAD process from such an attack, this research paper presents a better and secure DAD process, in which, a new node and the existing node transmit only a partial address and both nodes preserve a portion of the address. In this way, neither the existing nor the new malicious node can know the full address of each other, so they can not disrupt the DAD process. Experimental results indicate that the address success rate (ASR) of the proposed scheme outperformed existing DAD solutions in the presence of a malicious node. Moreover, the only partial address is transmitted by the nodes in the network hence reduces addressing cost and energy consumption.
