Abstract (en)

[origin: FR2789203A1] The invention concerns a method for controlling access to an electronic key for an electronic lock, within a predetermined time slot, which consists in: previous to all attempt at accessing, storing in the lock a control time value (VHS), delivered by a real time clock of an external validating entity; then, at each accessing attempt, in the key, reading a time slot (PH); storing a testing time value (VHC), delivered by the validating entity; transmitting from the key to the lock the time value (PH) and the testing time value (VHC); in the lock, verifying the conformity of the testing time value (VHC) with the time value (PH), and with the control time value VHS); in case of conformity, allowing access, and updating the control time value (VHS), from the transmitted testing time value (VHC); in case there is no conformity, access is prohibited.
