[1] patch at http://www.chronox.de/jent/jitterentropy-20130508.tar.bz2

An implementation of a CPU Jitter random number generator is released
at http://www.chronox.de/ . The heart of the RNG is about 30 lines of
easy to read code. The readme in the main directory explains the
different code files.

The documentation of the CPU Jitter random number generator
(http://www.chronox.de/jent/doc/index.html and PDF at
http://www.chronox.de/jent/doc/CPU-Jitter-NPTRNG.pdf -- the graphs and
pictures are better in PDF) offers a full analysis of:

- the root cause of entropy

- a design of the RNG

- statistical tests and analyses

- entropy assessment and explanation of the flow of entropy

The document also explains the core concept to have a fully
decentralized entropy collector for every caller in need of entropy.

The appendix of the documentation contains example use cases by
providing link code to the Linux kernel crypto API, libgcrypt and
OpenSSL. These implementations follow the concept of
decentralized entropy collection.

The man page provided with the source code explains the use of the API
of the CPU Jitter random number generator.

The test cases used to compile the documentation are available at the
web site as well.
