Abstract

An automated system is provided. Examples of automated systems include processors for calculation which implement a secure boot process based on the plurality of numbers; chip cards for authentication; telecommunication equipment; programmable logic controllers, control devices for railways, etc. The operation is controlled depending on whether a sequential test for randomness of a plurality of numbers from a physical random number generator is marked as failed. This has the advantage that an online-test for integrity of the plurality of numbers is possible at a high accuracy and low latency.
