A control method for operating an electric lock by using a portable device includes the portable device obtaining an encrypted message according to an encryption function; the portable device transmitting the encrypted message to the electric lock; the electric lock decrypting the encrypted message according to a decryption function; and the electric lock determining whether to perform an action according to a decryption result of the encrypted message.

The present disclosure provides a method and a system for offline verification code generation based on a smart door lock system. The method may include in response to an unlocking event, recording, by a mobile terminal, a trigger time of the unlocking event; in response to the unlocking event, sending, by the mobile terminal, a request for unlocking verification information to a cloud server, wherein the request for the unlocking verification information is used to request the cloud server to return a verification code of a smart door lock, and the unlocking verification information includes a private key seed of the smart door lock and the trigger time; and receiving, by the mobile terminal, the verification code of the smart door lock for opening the smart door lock generated by the cloud server based on the private key seed and the trigger time.

Methods, systems, and devices relating to administration of a portable electronic key are disclosed. The portable electronic key is configured for controlling access to an electronic locking device. A motion detection sensor detects a movement of the portable electronic key. Based on the movement of the key corresponding to a disabling movement, access to the electronic locking device is modified. A wireless communications link between the portable electronic key and an access administration device can facilitate an exchange of messages related to a status of the portable electronic key.

Various aspects of the disclosure relate to monitoring a physical location to determine and/or predict anomalous activities. One or more machine learning algorithms may be used to analyze inputs from one or more sensors, cameras, audio recording equipment, and/or any other types of sensors to detect anomalous measurements/patterns. Notifications may be sent one or more devices in a network based on the detection.

An electronic key management system assisting device including: a connector (31) that is mounted in a vehicle and is used for a connection with an in-vehicle authentication device communicating with a management server using an in-vehicle communication device; and a requester (35B) that requests the management server to transmit an execution key for obtaining a permission for a transition to a registration mode in which an electronic key of the vehicle is registered in the in-vehicle registration device or an invalidation mode in which the electronic key registered in the in-vehicle registration device is invalidated using a communication device other than the in-vehicle communication device in a case which the in-vehicle authentication device connected through the connector is not able to communicate with the management server using the in-vehicle communication device.

A vehicle authentication apparatus including an acquisition unit (65D) configured to acquire information indicating a content of a manipulation on a vehicle from a detection unit mounted on the vehicle; a manipulation determination unit (65E) configured to determine whether a predetermined collaborative manipulation executable by two or more manipulators is performed on the basis of information acquired by the acquisition unit; and an execution unit (65F, 65H) configured to execute a registration process of registering an electronic key of the vehicle in the on-vehicle authentication apparatus or an invalidation process of invalidating the electronic key registered in the on-vehicle authentication apparatus, in a case that it is determined by the manipulation determination unit that the collaborative manipulation is performed.

Methods, systems, and devices relating to administration of a portable electronic key are disclosed. The portable electronic key is configured for controlling access to an electronic locking device. A motion detection sensor detects a movement of the portable electronic key. Based on the movement of the key, a wireless communications link is established between the portable electronic key and an access administration device for exchanging messages related to access control information.

An electronic key system is provided with: an electronic key issuing apparatus configured to issue an electronic key associated with a moving body; a determinator configured to determine whether or not an electronic key with a first key code as the electronic key is normal; and a requester configured to request the electronic key issuing apparatus to reissue the electronic key on condition that it is determined by the determinator that the electronic key with the first key code is not normal. The electronic key issuing apparatus is configured to issue an electronic key with a second key code, which is different from the first key code, as the electronic key, on condition that the electronic key issuing apparatus is requested to reissue the electronic key.

A control method for operating an electric lock by using a portable device includes the portable device obtaining an encrypted message according to an encryption function; the portable device transmitting the encrypted message to the electric lock; the electric lock decrypting the encrypted message according to a decryption function; and the electric lock determining whether to perform an action according to a decryption result of the encrypted message.

One variation of an upgrade kitfor an ignition key corresponding to a vehicle and including an immobilizer transponder and a keyless entry transmitterincludes: a wireless jammer configured to interfere with wireless transmission from the immobilizer transponder; a wireless receiver configured to receive an unlock request from an external device; a relay configured to actuate the keyless entry transmitter to unlock a door of the vehicle in response to the unlock request; and an enclosure configured to contain the wireless receiver and a portion of the ignition key.
