Due to infrastructure - less networks and multi - hop communication features of Mobile Ad hoc NETwork (MANET), every node in MANET has to cooperate with each other. Therefore, node security becomes one of the important research areas of MANET. The resources that provided to MANET nodes such as battery power, memory, and bandwidth are limited. As a result, developing a resource-aware node authentication protocol becomes challenge for researchers. The proposed protocol provides One Time Node Authentication (OTNA) for every node joining MANET. To achieve this, the OTNA protocol provides one additional field \"Status\" in the routing table of the legitimate nodes, and the Malicious Node Table (MNT).
