LIGHTWEIGHT SECURE NEIGHBOR DISCOVERY PROTOCOL FOR LOW-POWER AND LOSSY NETWORKS

摘要

An apparatus comprising a network node configured to support a lightweight secure neighbor discovery (LSEND) protocol for securing neighbor discovery protocols (NDP) for energy-aware devices, wherein the network node is configured to wirelessly communicate with a host node, wherein the network node is configured to exchange LSEND protocol messages with the host node, and wherein the LSEND protocol uses reduced public key and signature sizes and more lightweight signature calculations in comparison to a secure neighbor discovery (SEND) protocol for securing NDP communications that are more suitable for low-power and lossy networks (LLNs).
