METHOD FOR PRODUCING NODE ID OR LAMPORT SIGNATURE KEY AND ITS USING METHOD FOR NODE CERTIFICATION IN WIRELESS NETWORK

摘要

A method for generating a node ID and a key in a wireless network environment and a node authentication method using the same are provided to perform the node authentication safely and efficiently through the cooperation between nodes in a wireless network environment in which an authentication service does not exist. Unique secret values of each node forming a wireless network are generated(301). An arbitrary node generates pairs of the secret values through its own secrete value(302). Hash values are generated through one way application of hash function to generated pairs of secret values(303). A node ID is generated through XOR bit operation of the generated hash values(304).
