Abstract
The present invention relates to a security control comprising a first controller having a first clock generator for generating a first clock signal, a separate second controller having a second clock generator for generating a second clock signal, wherein the first clock signal is output to a first input of the first controller and to a first input of the second controller, and the second clock signal is output to a second input of the first controller and to a second input of the second controller. In addition, the present invention relates to a method for operating a security control.
Claims12
A security control, comprising:
- a) a first controller having a first clock generator for generating a first clock signal);
- b) a separate second controller having a second clock generator for generating a second clock signal;
- wherein
- c) the first clock signal is output to a first input of the first controller and to a first input of the second controller;
- and
- d) the second clock signal is output to a second input of the first controller and to a second input of the second controller.
A method for operating a security control comprising a first controller having a first clock generator and a separate second controller having a second clock generator, wherein the method comprises the following steps:
- a) generating a first clock signal by means of the first clock generator;
- b) generating a second clock signal independent of the first clock signal by means of the second clock generator;
- c) outputting the first clock signal to a first input of the first controller and at a first input of the second controller;
- and
- d) outputting the second clock signal to a second input of the first controller and to a second input of the second controller.
