ELECTRONIC SYSTEM FOR CONTROLLING THE OPENING OF AN OPTO-ELECTRONIC LOCK OF AN ACCESS DOOR, RELATIVE OPTO-ELECTRONIC LOCK AND OPTO-ELECTRONIC KEY FOR OPENING THE LOCK

摘要

It is disclosed an electronic system (10) for controlling the opening of a lock of an access door of a limited environment. The system comprises an opto-electronic key (2) and an opto-electronic lock (3) in the case of operation of the system in an offline mode, and further comprises a network server in the case of operation of the system in an online mode. The opto-electronic key (2) comprises an optical source configured to generate an optical beam (F_O) carrying a data packet (30) which comprises a first field containing a key identifier (KEY_ID) and a second Payload field containing a user identifier (USER_ID) and a Time-based One-Time Password (TOTP tx), wherein the key identifier is in plain text, whilst the Payload is encrypted in case of use of symmetric cryptography.
