Abstract

본 발명은 도난방지 시스템을 동작시키기 위한 방법 및 도난방지 시스템에 관한 것이다. 로크(1)는 키(2)에 랜덤 넘버(ramdom number)를 전송한다. 키(2)는 랜덤 넘버에 암호 알고리즘을 공급하로 로크(1)에 코드신호를 다시 전송한다. 로크(1)에서는 코드신호가 랜덤 넘버에 동일한 암호 알고리즘을 공급함으로서 만들어진 적정코드신호와 비교된다. 해제신호는 적정 코드신호와 수신된 코드신호의 비트가 완전히 일치하지 않을 경우조차 본 발명에 따라 발생된다.The present invention relates to a method and an antitheft system for operating an antitheft system. The lock 1 sends a random number to the key 2. The key 2 transmits the code signal back to the lock 1 by supplying an encryption algorithm to the random number. In the lock 1, the code signal is compared with the appropriate code signal produced by supplying the same encryption algorithm to the random number. The release signal is generated according to the present invention even when the bits of the proper code signal and the bits of the received code signal do not coincide completely.
