The invention relates to a system implementing a mobile telephone (20) to which a master user authorized to program a lock (22) has access. A remote management site (10) includes a database (12) of locks and authorized users, having each lock, a list of authorized users with corresponding access rights, as well as an accreditation data generator (14). The accreditations are encrypted acoustic accreditations in the form of single-use audio signals, suitable for programming locks indexed in the database by the access rights indexed in the database and/or by additional data. The system includes a means for securely transmitting the encrypted acoustic accreditations from the management site to the mobile telephone of the master user. The lock (22) includes an electro-acoustic transducer (54) that is suitable for picking up acoustic accreditations reproduced by the telephone placed beforehand near the lock, as well as a means for recognizing, analyzing and authenticating the picked-up acoustic accreditations, and for programming access rights and/or additional data upon recognizing a compliant accreditation. |
