Unpredictable random number generator based on mobile sensors

Cryptographic applications need quality random number generators for reaching a high level of security. As the industry is moving forward at a high pace and the mobile paradigm emerging, new sources of randomness arise. One of them is the new generation of phones, also known as smartphones. We propose an unpredictable random number generator, which, using the hardware sensors of a modern phone, is able to produce high quality sequences of random bits.
