Abstract

Embodiments include method, systems and computer program products for extracting entropy from mobile devices to generate random numbers. In some embodiments, first vibration data may be received from a first device. Second vibration data may be received from a second device. A first piece of entropy data may be generated using the first vibration data and a second piece of entropy data may be generated using the second vibration data. The first piece of entropy data and the second piece of entropy data may be aggregated. The first piece of entropy data and the second piece of entropy data may be stored in an entropy pool.
