Abstract
To control the device using the electronic circuit chip is loaded in the apparatus, the chip stores a series of pseudo-random number therein. When the chip secret unit receives a first digital generated by the control computer generates a pseudo random number sequence in accordance with a secret algorithm stored in the chip unit; generating a first digital information comprises a sequence number when entering the control computer device, serial device into the read-only memory chips, device serial number that is permanently constant electronic circuit portion. Also discloses the use of various devices into which it's chip number.
