The generation of high quality random numbers is crucial to many cryptographic applications, including cryptographic protocols, secret of keys, nonces or salts. Their values must contain enough randomness to be unpredictable to attackers. Pseudo-random number generators require initial data with high entropy as a seed to produce a large stream of high quality random data. Yet, despite the importance of randomness, proper high quality random number generation is often ignored. Primarily embedded devices often suffer from weak random number generators.
