Abstract
A method and a device are provided, in particular a transponder, for generating a random number by a linear feedback shift register, wherein a first seed is generated by means of a first automaton, a second seed is generated by means of a second automaton, the first and second automata operate using different functional principles, so that the first and second seeds have different properties, and the shift register is reloaded with the first and/or second seed.
