Subject: Re: [RFC][PATCH 0/6] /dev/random - a new approach
Date: Thu, 21 Apr 2016 22:51:55 -0400	[thread overview]
Message-ID: <20160422025155.GA6690@thunk.org> (raw)

I still have a massive problem with the claims that the "Jitter" RNG
provides any amount of entropy.  Just because you and I might not be
able to analyze it doesn't mean that somebody else couldn't.  After
all, DUAL-EC DRNG was very complicated and hard to analyze.  So would
be something like

   AES(NSA_KEY, COUNTER++)

Very hard to analyze indeed.  Shall we run statistical tests?  They'll
pass with flying colors.

Secure?  Not so much.
