However, while radio frequency technology is widely used, it also brings security risks
This hidden danger originates from the "codec" setting of radio frequency technology. Since the transmitting and receiving codes are one-to-one corresponding and constant, once the code is mastered, it can be easily cracked

The present invention relates to a detection-proof electronic anti-theft apparatus and use thereof with its structure being characterized in that: 1) the remote controller is constituted by connecting a keyboard circuit, a control circuit and a radio frequency transmitting / receiving circuit; 2) the unblocking mechanism is constituted by connecting a radio frequency receiving / transmitting circuit,a processing control circuit and a driving circuit; 3) the remote controller is used for transmitting an identification code; the unblocking mechanism is used for receiving the identification code, judging whether the identification code is right, and generating a new station identification code and transmitting a challenging signal to the remote controller if the identification code is right; atthe same time, the processing control circuit instructs unlocking of the driving circuit; after receiving the challenging signal, the remote controller automatically generates a new station identification code identical to that of the unblocking mechanism. In accordance with the present invention, by applying radio frequency technique in combination with singlechip technology, it is realized thatthe encoding and decoding values can continuously change the identical values at the same time, resulting in that the encoding and decoding values at this time are different form that of the last time, then correctness of personal identification is ensures. Said apparatus is suitable for anti-theft executing in motor vehicles, household and public places.
Description
technical field [0001] The invention relates to an anti-detection electronic anti-theft device and its application, which is suitable for anti-theft in motor vehicles, families and public places. It belongs to the technical field of electronic anti-theft equipment. Background technique [0002] At present, with the rapid development of CMOS technology and the maturity of medium and high-density integrated circuit technology, the enhancement of the function and reliability of radio frequency integrated circuits, radio frequency technology has been widely used in various fields such as industry, engineering, identification, and civil use. . However, while radio frequency technology is widely used, it also brings security risks. This hidden danger originates from the "codec" setting of radio frequency technology. Since the transmitting and receiving codes are one-to-one corresponding and constant, once the code is mastered, it can be easily cracked [0003] The "identificati...
