Neighbor Discovery (ND) protocol was proposed to discover neighboring hosts and routers in IPv6 wire/wireless local networks. ND protocol, however, has a problem that it is vulnerable to network attacks because ND protocol allows malicious users to impersonate other legitimate hosts or routers by forging ND protocol messages. To address the security problem, Secure Neighbor Discovery (SEND) protocol was proposed. SEND protocol provides address ownership proof mechanism, ND protocol message protection mechanism, reply attack prevention mechanism, and router authentication mechanism to protect ND protocol. In this paper, we design and implement SEND protocol in IPv6 local networks. And also, we evaluate and analyze the security vulnerability and performance of SEND protocol by experimenting the implemented SEND protocol on IPv6 networks.
