  • Extracting Entropy from the Vibration of Multiple Machines
    Publication number: 20150301803
    Abstract: Generating a pool of random numbers for use by computer applications. Vibration sensors are placed throughout a machine and collect entropy data from the measurements of the vibration sensors. The data is then filtered and sent via secure connection to a second machine to be added to the second machine's 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.
