Abstract: An access control method is disclosed in which a lock device provides conditional access to a protected environment by short-range wireless communication with a key device having a key device identifier (KD_ID). In the method, the lock device requests the key device to provide a challenge response to a challenge generated by the lock device based on a challenge code kept by the lock device. The lock device receives the challenge response from the key device. The challenge response is generated by a remote administration server and is based on the key device identifier of the key device. The generated response is sent to the key device and forwarded from the key device to the lock device. The lock device then verifies the received challenge response based on the challenge code and on the key device identifier of the key device.

Abstract: A method of updating lock access data for an electromechanical lock is disclosed. The lock is of a type capable of being actuated by a user desiring to open the lock with a key having electronic key data stored therein. Updated lock access data for the lock may be configured by an administrator from a remote site and communicated to the lock using public networks. According to the method, updated lock access data from the remote site for the lock is transmitted over a telecommunication channel to a mobile terminal. The updated lock access data is transmitted from the mobile terminal to the key using short-range wireless communication. When the user attempts to open the lock with the key, the updated lock access data as received from the mobile terminal is forwarded from the key to the lock. The lock verifies that the user is trusted and then accepts the updated lock access data as received from the key.
