Provided is a multi-locking device including a locking device management unit configured such that, when a user requests same to grant a right to open/close a door, same converts information regarding a granted right regarding the door into a QR code, outputs same, and provides same to the user, a door locking device configured to receive the information regarding a granted right regarding the door from the locking device management unit, and a QR code reader unit configured to receive the QR code from the user and provide same to the door locking device.

The present disclosure includes a system for re-establishing a Bluetooth Low Energy (BLE) pairing PIN key to repair a secure connection between a mobile device and vehicle. The system may detect an error state, and provide a prompt to the user to determine if they wanted to intentionally remove their account. Responsive to an affirmative response from the user that the removal of the connection credentials was intentional, the system may send a revoke request to a server associated with the vehicle. Responsive to a user input that indicates that the removal of the credentials was unintentional, the vehicle may fetch an encrypted PIN seed of the BLE pairing PIN from memory or request the PIN seed from the server. The PIN seed re-establishes the secured pairing of the mobile device and the vehicle infotainment system without undergoing a new device setup procedure.

A wireless communication system includes: an in-vehicle unit mounted on a vehicle and capable of wirelessly transmitting an access signal when an operation unit is operated; a portable device capable of wirelessly transmitting a vehicle-specific authentication code on a condition that the access signal is received; and a determination unit capable of determining whether or not the authentication code is a regular authentication code on a condition that the authentication code is received. Start of a driving source of the vehicle is permitted or running of the vehicle is enabled when the determination unit determines that the authentication code is the regular authentication code, and a security mode in which a function of transmitting the access signal by the in-vehicle unit or a function of transmitting the authentication code by the portable device is stopped can be set by a predetermined setting operation.

A method and system for controlling the use of a temporary password is provided, and the method includes the steps: generating by a random code generator end a preset number of temporary passwords after successful matching between the random code generator end and the random code use end; sending by the random code generator end at least one temporary password among the preset number of temporary passwords to the random code use end for storage therein to form a preset temporary password; and receiving a current temporary password, comparing the current temporary password with each of the pre-stored temporary passwords, and indicating successful verification if the current temporary password is the same as one of the pre-stored temporary passwords. The method can generate multiple temporary passwords at once, and control and manage the use of temporary passwords by adding function codes to the temporary passwords.

A security processing method for a car sharing service includes: a smart terminal encrypting a second random code according to a first smart terminal encryption key, to obtain a first cyphertext, the first smart terminal encryption key having a first random code and order form information from a cloud server; the smart terminal receiving a third random code from a vehicle, the vehicle obtaining the third random code by decrypting the first cyphertext according to a first vehicle encryption key that includes the first random code and the order form information sent by the cloud server; the smart terminal subjecting the second random code and the third random code to comparative verification, to obtain an identity authentication result; the smart terminal sending, if the identity authentication result has passed, encrypted service data to the vehicle; and the vehicle decrypting the service data to execute the service data.

Systems and methods are provided and include a sensor that is configured to generate a first link key data packet. A control module of a vehicle is configured to generate a second link key data packet. In response to (i) a first authenticated response of the first link key data packet matching a second authenticated response of the second link key data packet and (ii) a user device being connected to a communication gateway of the control module by a Bluetooth low energy (BLE) communication link, the sensor is configured to communicate signal information to the control module using a hardwire link that electrically couples the control module and the sensor. The signal information includes information corresponding to physical characteristics of the BLE communication link.
