Abstract: The invention relates to a system including a lock (10) provided with electronic NFC transceiver circuits and electric circuits for controlling mechanical locking/unlocking members, and a portable telephone (16) provided with circuits for NFC mode of operation. The telephone comprises means for initializing the lock, said means including means for: downloading, from a remote site (20), an applet and elements required for initializing the lock; verifying, using the telephone, the identifier and the transport key stored in the lock against the downloaded ones; deactivating the transport key of the lock; loading, onto the lock, a unique random algorithm and a cryptographic key that have been downloaded; and generating a message notifying of the termination of the initialization of the lock.

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.

Abstract: A management site (10) generates an encrypted message by a public-key symmetrical encryption algorithm, the algorithm and the key being selected by the management site among a memorized list. The message (DKE), which includes an identifier of the encryption algorithm and key used, is transmitted to a portable device (16), which stores it. For the use, the message is transmitted to a secured module (20) that decrypts it, checks its compliance with an internal reference, and generates a digital accreditation controlling the unlocking of a lock device (18). The decryption is operated with the algorithm and the key recognized based on the identifiers of the message, selected among a list memorized by the secured module.

Abstract: The invention relates to a system that makes use of a mobile telephone (22) to which a user authorized to open a lock (28) has access. According to the invention, a remote management site (10) includes a database (12) of authorized users identified by the mobile telephone number thereof, as well as a data credential generator (14). The credentials are crypto acoustic credentials (CAC) in the form of single-use audio signals and are generated from digital data credentials (DDC) that are normally employed by the lock when the latter is used with a badge or a card. The system includes means (16, 18, 20) for securely transmitting the acoustic credentials to the user's telephone. The lock (22) picks up the acoustic credentials reproduced by the telephone pre-positioned near the lock and extracts the digital data credentials from the picked-up crypto acoustic credentials and, subsequently, the lock applies the thus-extracted digital data credentials to the analysis, authentication and control means of the lock.

Abstract: The invention relates to a system comprising a lock (40) provided with NFC circuits, a mobile phone (32) also provided with NFC circuits, a remote lock management site (18), and a mobile network operator (20). For each lock, the management site generates a unique random algorithm, a unique identifier (PUID) and transport keys and transmits the identifier and the transport keys to a lock manufacturer (16). The mobile network operator receives a unique lock identifier (PUID) from the user and transmits same to the handling site which, in return, transmits the unique random algorithm, the cryptographic key, the transport key and the user key corresponding to the lock to the phone. The phone implements the initial programming of the lock, by loading the unique random algorithm, the cryptographic key and the user key onto the lock and, subsequently, the phone activates a secure cryptographic procedure.
