Abstract
The method includes the steps of: a) generating by an application software (SWA) a message forming a key (DKE) comprising an encrypted data field containing a time-stamping or sequencing time marker; b) transferring the message to a portable communication device (CD), held by a user; c) transmitting the message, by short-range transmission, from the communication device to a reading interface (ERED) coupled to a lock device (LOCK); d) analyzing the message by decrypting the data field and checking the consistency of the time marker with an inner clock of the interface or with a sequence number memorized in the interface; and e) in case of compliant message, sending from the interface to the lock device a digital accreditation (OPEN) stored in memory in the interface and to operate the lock device unlocking upon recognizing the compliance of said digital accreditation.
