METHOD FOR GENERATING TRUE RANDOM NUMBERS ON A MULTIPROCESSOR SYSTEM AND THE SAME

摘要

The invention relates to a method for generating random numbers on multiprocessor systems and a multiprocessor system for generating true random numbers using the method. The object of the invention to generate truly random numbers with high entropy in a multiprocessor system with little additional effort to chip area and power dissipation is solved by the steps of: measuring a phase error signal of a clock generator circuit of a first and a second processing unit respectively, forwarding the phase error signal of the respective clock generator circuit of the first and second processing unit to a true random network, combining the phase error signal of the clock generator circuit of the first processing unit and the phase error signal of the clock generator circuit of the second processing unit in the true random network to random bit streams, picking-up a random bit stream of the true random network, passing the respective random bit stream back to the respective processing unit especially to a random generator for outputting true random numbers and a multiprocessor system accordingly.
