ABSTRACT:
A system for the validation and verification of base stations and mobile stations within a cellular radio communications network. The system includes a fixed key and a changeable key which are applied as inputs to an authentication algorithm. The algorithm generates key-dependent responses, at least one of which is independent of the changeable key. The responses generated by a particular mobile station are compared to the responses generated by the network and the presence of fraudulent users may be detected.
