Abstract

Disclosed is a method for generating a plurality of result values (Pi), each of which has a predefined characteristic. In order to generate each result value (Pi), a basic value (Ti) is determined, a generator value (Zi) is calculated, and the result value (Pi) is determined, an externally precalculated and stored adjustment value (Di) being used for making the result value (Pi) have the predefined characteristic. Corresponding steps are carried out in a method for precalculating a plurality of adjustment values (Di). A data carrier (12) and a device (10) are set up to carry out such methods. The inventive technique for generating result values can be used in environments having limited computing capacity and a limited memory unit, e.g. chip cards or chip modules.
