Title: Jürgen Krühn: Innovator in Key and Lock Technology
Introduction
Jürgen Krühn is a notable inventor based in Berlin, Germany. He has made significant contributions to the field of key and lock technology, holding a total of 5 patents. His innovative approaches have enhanced security measures in locking systems.
Latest Patents
One of his latest patents is a key and lock device that introduces a method of authorizing a key or lock device. This method involves creating a first user device and a first system device used in a first level of a lock system, such as at a manufacturer. A first encryption key is stored in both the first user device and the first system device. When the user device is to be shipped to a second level of the lock system, such as a locksmith, an authentication process is carried out using the first encryption key. If the authentication is successful, a software operation replaces the first encryption key with a second encryption key, which is then stored in the second system and user devices. This process prevents unauthorized use of keys and locks.
Another patent by Krühn describes a key and lock device that comprises a key with a first electronic circuit and a lock with a second electronic circuit. Both the key and the lock store secret information unique to each device. They exchange a random number through connectors and perform calculations based on this random number and the secret information. If the calculations match, an electrical blocking mechanism is moved to a non-blocking position, allowing access.
