Method for classifying and/or generating random bits, for mobile applications, involves classifying output signal from logic elements in ring oscillator circuit as random coincidence signal/non-random function of occurring bit patterns

摘要

The method involves providing (S1) output signals of logic elements in ring oscillator circuit, Input signals are partially fed back into logic elements for outputting into output signal. The output signals from logic elements are detected (S2) for generating check bit, and the generated check bits are assigned (S3) to respective bit pattern. A selected output signal is classified (S4) as random coincidence signal or non-random function of occurring bit patterns. An independent claim is included for a device for generating random bits.
