Propose a new approach for securing DHCPv6 server in IPv6 link-local network

Abstract

IPv6 is becoming more and more entrenched, especially as the shortage of IPv4 address became obvious recently. Internet Protocol version 6 (IPv6) uses Dynamic Host Configuration Protocol for IPv6 (DHCPv6) for assigning the IPv6 address to hosts and provides the host with network configuration parameters. The DHCPv6 protocol may use to reveal host information and inject fake information into a host. Thus, the authentication and privacy of the DHCPv6 messages are a vital security component in the IPv6 network. This paper proposes a new security approach to provide privacy and security for the DHCPv6 message. The proposed approach utilized a hybrid cryptosystem and Message Authentication Code (MAC) algorithm to provide privacy and authentication. The paper also presents the expected results for the proposed approach and the future works.
