Abstract: The telecommunication network has a mobile terminal with functionality for providing wireless access to a public network via an access point and a connector for connecting to a hands-free unit, a data system and a public network. The mobile terminal is connected to said hands-free unit and automatically connecting the data system of the car to the mobile terminal upon the connection of the mobile terminal to the hands-free unit. The mobile terminal connects the data system to the public network over a wireless data exchange connection used by the mobile user terminal for wireless access to the public network.

Abstract: Invention shows an electro-optical key arrangement comprising for a key of the key arrangement comprises: a transmitter (LED1) arranged (G1,G2,G3) to transmit photon radiation at a wave-length range comprising at least one wave length, into a wave guide forming an optical path, a receiver (LED2) arranged to receive, said photon radiation on said at least one wave length, at least partly from said optical path, and to convert said photon radiation into an electric form to be used for an electric signal, and a detector circuit (D1,D2,D3) arranged to detect changes in said photon radiation received for forming a specific electric signal as a key (Q1,Q2,Q3) specific signal.

Abstract: A method for real-time authentication or authorization of a user (1) of a secured system (3) is based on using two authentication channels and an authentication device (4) from which the secured system can request authentication or authorization (6) over a secured information network connection (6, 9). One of the authentication channels is a telephone network (8), to which the authentication device (4) is connected. A user logging into the secured system (3) over the other channel (6) of the authentication channels must make a call to the authentication device over the telephone network by his or her telephone (2). The authentication device verifies that a call has been received from a telephone number of the user's telephone, and issues a positive verification response to the secured system. Upon receiving a positive response, the secured system provides a requested service through the other channel.
