			Malicious PLC devices could paralyze the whole network via DOS
			attacks, e.g., keep joining and leaving the network frequently, or
			multicast routing messages containing fake metrics. The security can
			be enhanced by using DTLS to authenticate a PLC device when it
			enrolles itself. If the PLC device is not direct neighbor to the
			PANC, where the authenticate is conducted, another PLC device which
			has joined the network can act as a proxy to help exchange the
			authenticate messages. The key used for encryption can also be
			negociated via DTLS.
