&gt; An observer of the produced random numbers can potentially deduce the next numbers from the first 1024 random numbers.<p>By definition, a cryptographically secure pseudorandom number generator cannot be predicted like that by a computationally bounded attacker.<p>Thus if any attacker could deduce the next number from &#x2F;dev&#x2F;random by observing the numbers before, the algorithms they adopt is fundamentally wrong, and nothing could the save the security in that case.
