ABSTRACT:
The present invention provides for an identification of a sender in a network, wherein first time-dependent data is generated at a sender on the basis of a first time. At least the first time-dependent data is communicated by the sender via a network to a receiver, which, in response to receiving the first time-dependent data, generates second time-dependent data on the basis of a second time. In order to verify the identity of the sender, the first and second time-dependent data are compared to determine a correspondence. Such a correspondence indicates that the sender is authorized to perform data communications with the receiver, i.e. indicates a successful verification of the identity of the sender.
