<p>The invention relates to a method for actuating a lock using a smart card capable of remotely communicating with an actuating device associated with said lock, wherein a digital identifier, referred to as a logic key, can be associated with said smart card. Said method includes the following steps: during each locking of the lock (30), said actuating device (20) records a logic key contained or to be contained in a so-called first smart card (1) which communicates with said actuating device (20), said logic key being a pseudo-random number, and then the lock is locked (30); and, during each unlocking of the lock (30), said actuating device (20) compares the logic key contained in a so-called second smart card (1'), which communicates with said actuating device (20), with the logical key contained in said first smart card and recorded during the last locking of the lock (3), and then the lock (30) is unlocked only if the logic keys contained in the first (1) and second (1') smart cards are identical. The invention can be used for locks for public use.</p> |
