Abstract
Abstract Apparatus and a method are described for providing for multiple secure functions in a host or wireless radiotelephone. Access to the functionality of the radiotelephone is provided by means of a smart card or security token features contained therein. The determination of the secure function which is accessed is determined by encrypted credential information carried in the smart card. The smart card may be used for numerous applications, but is particularly useful in conjunction with radiotelephone devices having a plurality of secure communication levels. The radiotelephone device will activate the secure levels based on the security level algorithm carried in the smart card.
