random.c from /linux-2.6.26.5/drivers/char random.c
/dev/random
it is useless to feed more than "poolsize" bit of data in /dev/random at a time.
- data put into /dev/random goes through a CRC32 pass before being put into the pool
monitoring in /proc/sys/kernel/random
- boot_id : random data fetched at boot time
- uuid : random data for new disk devices ID (a new UUID for a new partition)
- entropy_avail : instant size of entropy available (in bits)
- poolsize : max size of the entropy pool (in bits)
read_wakeup_threshold : entropy threshold when processes waiting for entropy are waken up to fetch new random data (/dev/random only)
write_wakeup_threshold : entropy threshold under which the pool is feed with data ( cat randomdata > /dev/random )
- entropy pool monitoring:
while sleep 1; do date; cat /proc/sys/kernel/random/entropy_avail ; done
- diehard test
for i in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 ; do
dieharder -d $i -g 63 ;
done
