摘要
in a device and a portable datentru00e4geranordnung formed informationsu00fcbertragungssystem is an authentication of a systemteils by another user agent after the challenge and response principle.the portable datentru00e4geranordnung is a wertespeicher and the associated controls and a nonvolatile, containable fehlerzu00e4hler formed.when the authentication is initially in the portable datentru00e4geranordnung a lock for the conduct of operations, set up only by changing the fehlerzu00e4hlerstandes must be repealed.the device will be random data as challenge data to portable datentru00e4geranordnung transferred, after the fehlerzu00e4hlerstand incremental change and the barrier has been removed.in both the terminal and the portable datentru00e4geranordnung from the challenge data using at least one algorithm and secret key data (authentifikationsparameter ap3, ap4 calculated.the terminal transmits its authentifikationsparameter ap3 as response to portable datentru00e4geranordnung where they use the authentifikationsparametern ap4 calculated are compared. in accordance of the respective authentifikationsparameter ap3, ap4, the wertespeicher wiederaufladbar and / or fehlerzu00e4hler ru00fccksetzbar.
