IPv6 nodes use the Neighbor Discovery Protocol (NDP) to discover other nodes on the link, to determine their link-layer addresses to find routers, and to maintain reachability information about the paths to active neighbors. SEcure Neighbor Discovery protocol (SEND protocol) is a security extension of neighbor discovery. The SEND protocol is designed to counter the threats to NDP. This paper presents the threats and security analysis for SEND and all the possible security options for more secure IPv6 neighbor discovery protocol.
