摘要:
A method of using a chip identification device is jointly performed by a chip mass-produced by a semiconductor manufacturing process, a first chip manufacturer making the chip, and a chip user assembling a product by using the chip. The method includes inputting a first published passcode, published by the first chip manufacturer, inputting a second published passcode published by a second chip manufacturer, inputting the first published passcode to the chip by the chip user, reading an aggregate of electronic output signals as a read code, sending the read code to the first chip manufacturer to compare the first output code and the read code. The chip is regarded as a counterfeit if the comparison is consistent.

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.
摘要:
A network of electronic appliances includes a plurality of network units of electronic appliances. The network units include a first network unit and a plurality of second network units. The first network unit is connected to at least one of the second network units. Each of the network units includes a stem server and a plurality of peripheral devices connected to the stem server. The stem server includes at least one passcode and at least one list of a plurality of registration codes. Each list is associated to a respective passcode. Each registration code of one list associating to one passcode corresponds to a respective peripheral device. Each registration code is generated in response to a respective passcode using physical randomness of a respective peripheral device in correspondence to the passcode. An address of each identification cell is defined by several word lines and bit lines.

摘要:
An example according to one embodiment includes a first coil and a second coil spaced apart therefrom. The system is supplied with power from a primary-side circuit to a secondary-side circuit and vice versa. The primary-side circuit includes the first coil. The secondary-side circuit includes the second coil. The primary-side circuit connects to a first converter that converts direct current into alternating current and vice versa. The first converter connects to second converter that converts direct current into alternating current and vice versa, and the second converter further connects to a commercial power supply. The secondary-side circuit connects to third converter that converts direct current into alternating current and vice versa, and the third converter further connects to direct current power supply of a moving body. Bidirectional power transfer is performed only by a switching operation of the first converter, the second converter, and the third converter.
