摘要

For the secure administration of a lock (11), in particular for a safe, by means of a computer (14), it is proposed that a initial key and a customer key is generated, the customer key in a dongle (15) are stored, and that to the computer a secure input unit (16) is connected. initial key customer key and can form an asymmetrical key pair, or both may be symmetric. In the first case, the initial key in the lock (11) is stored, in the second case, in addition, in a file (17), the only with the customer key can be decoded. By means of the customer key and of the initial key is between the computer (14) or input unit (16) on the one hand and the lock (11), on the other hand, a session - key is negotiated, after which the in the input unit (16) input information with the session - key in encoded form to the lock (11) is transmitted. In this way, a secure connection also be produced via the internet.n="17"
