Method of Physical Chip Identification for Networks of Electronic Appliance

摘要

A technology precluding attacks through peripheral devices thefts to a network of electronic appliance, by utilizing physical chip identification devices, is disclosed. The electronic appliance in the network are divided into the peripheral devices and stem servers managing registration information of the peripheral devices, wherein the stem servers serve as central control using software, and the peripheral devices are managed at device-level by having physical chip identification devices, thus the security of the whole network is efficiently reinforced.

主权项

1. A network of electronic appliance divided into a plurality of network units, each comprising:
a stem server; and a plurality of peripheral devices only connected to the stem server, wherein in the network unit, the stem server includes at least a passcode and a list of registration codes formed with a plurality of the registration codes corresponding to each of the peripheral devices connected to the stem server, and the registration codes are generated in response to the passcodes by using intrinsic physical randomness of each of the peripheral devices, and stored in the stem server in advance, wherein each of the peripheral devices carries a different chip identification device sending output signals to the stem server in response to the passcodes received from the stem server, and the output signals are generated based on the intrinsic physical randomness of each of the peripheral devices, wherein the stem server compares each of the output signals with the list of the registration codes, and determine a certification of each of the peripheral devices.
