The process of neighborhood establishment in an IPv6 network is made out through the NDP (Neighbor Discovery Protocol). Using ICMPv6 messages (NS - Neighbor Solicitation and NA - Neighbor Advertisement) which contains the IP address to be resolved, is exposed during the exchange of messages, making communication vulnerable to various types of attacks. This paper presents a proposal for a safer neighborhood establishment using the DH and HMAC algorithms. Experiments were performed in virtualized environments with the objective of analyzing the efficiency of the modification proposed in the NDP.
