ELECTRONIC DEVICE NETWORK, ELECTRONIC DEVICE AND INSPECTION PROCESS THEREOF

Japanese Patent JP2018011299

A

PROBLEM TO BE SOLVED: To provide chip authentication unable to be physically duplicated, by taking advantage of physical randomness of an authentication element group produced integrally with manufacture of semiconductor chips, as a unique physical address of a network node having physical reality.SOLUTION: In an electronic device network, electronic devices which make up the network are separated into two types of nodes, namely, a peripheral node and a core node managing registration information of the peripheral node. The core node performs central management and the peripheral node is mounted with a chip authentication device which cannot be physically duplicated. By managing a physical address of the peripheral node at a chip level, the electronic device network enables management and security of the entire network to be efficiently improved.SELECTED DRAWING: Figure 88
