/dev/random – a new approach
If I read this correctly, this new suggestion also keeps the entropy estimation voodoo:<p>&quot;By using the primary DRBG to serve &#x2F;dev&#x2F;random, the LRNG ensures that each random number generated by the primary DRBG must be backed by an equal amount of entropy that seeded the DRBG. Hence, the data derived from &#x2F;dev&#x2F;random is backed by information theoretical entropy.&quot;<p>(page 21 of the PDF documentation)
