Subject: Sources of entropy?
Date: Tue, 24 Mar 2009 18:47:28 -0400 [thread overview]
Message-ID: <200903241847.29104.rgetz@blackfin.uclinux.org> (raw)
I'm just wondering what people using on standard embedded/headless/diskless
targets (which do not have hw random number generators) as a source of
entropy - since networking was removed as an entropy source circa 2.6.26
On my target:
root:/> cat /proc/sys/kernel/random/entropy_avail
0
is about all I get... (since I'm not running any userspace utils yet).
I have seen rngd, clrngd, audio_entropyd, & video_entroyd - but I was just
wondering what others were actually using. (I was cautioned that everything
was pretty CPU intensive, since they all have a FIPS testing to ensure
randomness)...
Thanks in advance.
