摘要：
In our paper, we analyze possibilities to generate true random data in mobile devices such as mobile phones or pocket computers. We show how to extract arguably true random data with a probability distribution epsilon = 2(-64) close to the uniform distribution in the trace distance. To postprocess the random data acquired from the camera we use a randomness extractor based on the Carter-Wegman universal(2) families of hashing functions. We generate the data at the bit rate approximatively 36 bits per second - we used such a low bit rate only to allow statistical testing at a reasonable level of confidence.
