    • The invention relates to a security system for wireless networks, comprising a first portable unit (1) with a memory (3) for storing a worldwide unambiguous key record (4) provided for short-range information transmission of the key record (4). At least one wireless apparatus (2) of the network is provided with a receiving unit (7) comprising a receiver (9) for receiving the key record (4) and an evaluation component (11) of the apparatus for storing, processing and/or passing on the key record (4) or a part of the key record to a second component. Due to the key record, the apparatuses in the wireless network acquire a secret shared key by means of which the encryption and decryption of the transmitted useful data and/or the authentication is performed. In accordance with an optional embodiment of the invention, the key record in the portable unit can be derived from biometric characteristics of a user.
    • 本发明涉及一种用于无线网络的安全系统,其包括具有存储器(3)的第一便携式单元(1),用于存储提供用于密钥记录(4)的短距离信息传输的全球明确的密钥记录(4)。 网络的至少一个无线设备(2)设置有接收单元(7),接收单元(7)包括用于接收密钥记录(4)的接收器(9)和用于存储,处理和/ 或将密钥记录(4)或密钥记录的一部分传递给第二个组件。 由于密钥记录,无线网络中的装置获取秘密共享密钥,通过该秘密共享密钥执行发送的有用数据和/或认证的加密和解密。 根据本发明的可选实施例,便携式单元中的关键记录可以从用户的生物特征得出。

    • A lighting system and a method of operating the lighting system are described. A plurality of lighting units (10, 10′) each comprise, a lighting element (12) with a lighting control unit (14) for controlling its light output, and a communication unit (16, 16′) for communicating over a communication medium, e.g. RF or power line communication. The units (10, 10′) further have an optical receiver (18) for receiving light from other lighting units (10, 10′). A controller unit (20) is connected to the optical receiver (18), the communication unit (16, 16′) and the lighting control unit (14). In order to allow easy, automated set-up, at least in a configuration phase, the lighting units (10, 10′) send information by operating the lighting elements (12) in a modulated manner, and this information is received by a further lighting unit (10, 10′) observing the generated light. According to a first aspect, the lighting units (10, 10′) are grouped in clusters by turning on the lighting element (12) in a first lighting unit and generating cluster information depending on whether or not the emitted light is observed by further lighting units. According to a second aspect, lighting units (10, 10′) form a communications network and communicate with a joining lighting unit (66) by transmitting code data (78a, 78b) by operating the lighting element (12) according to a modulation sequence, and then transmitting configuration data (80) over the communication medium encrypted with the code data (78a, 78b).
