The patch set that can be downloaded at  provides a different approach to /
dev/random which I call Linux Random Number Generator (LRNG) to collect
entropy within the Linux kernel. The main improvements compared to the legacy
/dev/random is to provide sufficient entropy during boot time as well as in
virtual environments and when using SSDs or Device Mapper targets. A secondary
design goal is to limit the impact of the entropy collection on massive
parallel systems and also allow the use accelerated cryptographic primitives.
Also, all steps of the entropic data processing are testable. Finally
performance improvements are visible at /dev/urandom and get_random_bytes.
The design and implementation is driven by a set of goals described in 
that the LRNG completely implements. Furthermore,  includes a
comparison with RNG design suggestions such as SP800-90B, SP800-90C, and
