In this document, We consider Wireless Sensor Network (WSN) security and
focus our attention to tolerate damage caused by an adversary who has 
compromised deployed sensor node to modify, block, or inject packets. We 
adopt a probabilistic secret sharing protocol where secrets shared between two sensor nodes are not exposed to any other nodes. Adapting to WSN characteristics, we incorporate these secrets with bidirectional 
verification and multipath routing to multiple base stations to defend 
against HELLO flood attacks. We then analytically show that our defense
mechanisms against HELLO flood attack can tolerate damage caused by an 
intruder

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
