Abstract

Generating a pool of random numbers for use by computer applications. Vibration sensors are placed throughout a machine and collects information theoretic entropy data from the measurement of the vibration sensors. The data is then filtered and added to an entropy pool. Applications needing a random number may acquire a number from the pool. A method, computer program product and system to generate the pool are provided.
