Document Type and Number:
Japanese Patent JP2016181815
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a radio multi-hop network node (communication device) capable of improving security without increasing a communication traffic.SOLUTION: In a communication system, a distribution server, before inputting data into the radio multi-hop network, inputs an authentication code to distribute the data. When the distribution server inputs the authentication code into the network, each relay node checks whether a node adjacent to the relay node of concern has relayed the same authentication code after relaying the authentication code, so as to secure the integrity of the authentication code in a domino toppling manner.SELECTED DRAWING: Figure 1
