Abstract
In this paper, we have realized experimentally, for the first time to our knowledge, a parallel gen� eration scheme of high speed random numbers by using chaotic laser. In our setup, two broadband chaos sig� nals are obtained experimentally from a mutually coupled semiconductor lasers system. The bandwidths of these signals are over 10 GHz. Next, by using such chaos signals as entropy sources, two 10 Gbits/s physical random number streams are generated concurrently and successfully pass the NIST statistical tests. Our sys� tem is scalable and the rate of random numbers could be further enhanced by simply adding more channels.
