Title:
ネットワークにおけるノードの識別
Document Type and Number:
Japanese Patent JP2009535875
Kind Code:
A
Abstract:
A method of secure mutual identification of nodes (Nn) in a communications network comprising for each node a file (Fn) containing parameters descriptive of the node, each parameter being indexed by a cryptographic identifier of the node and an identifier of the parameter. An interface (IR) broadcasts from the node a message containing the cryptographic identifier of said node to the other nodes of the network. A unit (UC) transmits an identification request containing the cryptographic identifier of a first other node and the identifier of a parameter of said first other node requested by said node. A unit (HF) searches the file for a part of a parameter requested by a second other node as a function of the cryptographic identifier of said node and the identifier of the parameter transmitted by the second other node, and the interface transmits the part found of the parameter requested by the second other node to said second other node.
