SYSTEM FOR CONTROLLING ACCESS AUTHORIZATION |
摘要 |
The invention relates to a system for controlling access authorization, comprising a base device (BG) which receives a code word (CWx) containing a response (Rx). A computer (16) compares the response (Rx) with a reference response (Sx). Access authorization is granted if the response (Rx) and the reference response (Sx) match. A remote control (F1, ... Fx, ... Fn) transmits the code word (CWx). The system is characterized in that a challenge (Cx) transmitted by the base device (BG) is stored in the remote control (F1, ... Fx, ... Fn) to generate the code word (CWx).
