Abstract
A method for operating a multistage counter in only one counting direction is described. The counting value of a single-stage auxiliary counter that can be changed in only one counting direction is changed in predetermined counting values of the multistage counter. The respective counting value states of the multistage counter and of the single-stage auxiliary counter are registered. First authenticity data is generated by logically linking the counting value of the auxiliary counter to supplementary data.
