摘要： A key and lock device comprises a key having a first electronic circuit and a lock having a second electronic circuit. The key and the lock store secret information, some of which is unique for each device. The key and the lock exchange a random number through connectors and perform a calculation in the respective circuitry based on the random number and secret information. An electrical blocking mechanism is moved to a non-blocking position if a comparison of the calculations in the circuits gives the correct result.

摘要： A method of authorizing a key or lock device comprises the following steps: a first user device and a first system device used in a first level of a lock system, such as at a manufacturer, are created. A first encryption key is stored in 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 between the first user device and the first system device using the first encryption key stored therein. In case the authentication process was successful, a software operation is carried out by the first system device, by which the first encryption key stored in the first user device is replaced by a second encryption key. This second encryption key is stored in second system and user devices used in the second level of the lock system, thereby making the first user device operable with the second system and user devices. This prevents unauthorized use of keys and locks.

摘要： A key and lock device comprises a key and a standalone lock. The key has an electronic circuitry with a first memory and a contact. The lock has electronic circuitry with a memory, and a contact arranged to co-operate with the key's first contact. A blocking mechanism is adapted to block operation of the lock unless an authorized key is inserted in the lock. The memory of the key stores a public identification item of the key identifying a group of keys having identical mechanical codes. In the memory of the lock, there is provided a list of the public and secret identification items of authorized keys and a list of the public identification item of non-authorized keys. A key is authorized if the public and secret identification items are present in the list of authorized keys and the public identification item thereof is absent in the list of non-authorized keys.
摘要翻译：钥匙和锁定装置包括钥匙和独立锁。钥匙具有具有第一存储器和接触件的电子电路。锁具有具有存储器的电子电路，以及布置成与钥匙的第一接触件配合的触点。阻塞机构适用于阻止锁的操作，除非授权的钥匙插入锁中。密钥的存储器存储用于识别具有相同机械代码的一组密钥的密钥的公共识别项目。在锁的存储器中，提供了授权密钥的公共和秘密识别项目以及非授权密钥的公共识别项目的列表。如果公钥和秘密识别项目存在于授权密钥列表中并且其公开标识项目不在未授权密钥列表中，则授权密钥。

摘要： The invention relates to a lock-key system comprising a flat key (1), which is insertable into the keyway of a cylinder core (3), wherein grooves (4) and ribs (5) inside the keyway are assigned to corresponding ribs (5a) and grooves (4a) located on both flat sides of the key (1), wherein the key is subdivided from the key spine (6) to the key facing into different profile sections. The middle profile section is assigned to at least one groove (4) on one outer surface of the keyway (2) and to a rib (5) on the opposite outer surface of the keyway. Both the groove (4) as well as the rib (5) comprise a flank (4′, 5′), which extends perpendicular or substantially perpendicular to the center plane of the key or of the keyway, and comprise a flank (4″, 5″), which extends slantingly to this center plane. The perpendicular or substantially perpendicular flank of the groove faces the opposite slanted flank of the rib, and the perpendicular or substantially perpendicular flank of the rib faces the opposite slanted flank of the groove.
