+
+
+=== Curve25519 ===
+We need to create an accelerator or possibly a complete implementation of the Curve25519 EC based DH-excgange. We should be able to look at some previous work:
+
+* http://eprint.iacr.org/2013/375 - NaCl on 8-Bit AVR Microcontrollers. Includes an iterative implementation of Curve25519
+* http://cryptojedi.org/crypto/index.shtml - The code to the implementation
+* http://nacl.cr.yp.to/ - The main NaCl library by DJB.

+Preparation notes for the OpenHSM meeting 2013-12-05 --
+2013-12-06. The notes contains topics, questions and ideas
+I want to bring up, check and discuss on the meeting.

+ - LGPL
+ - http://openrisc.net/
+ - http://opencores.org/or1k/Main_Page
+ - https://en.wikipedia.org/wiki/OpenRISC
+
+- RNG
+ - More than one entropy source
+ - Just external sources
+ - User/vendor/implemented supplied
+ - One external, one internal
+ - YubiHSM entropy source: https://www.yubico.com/products/yubihsm/
+ - Haveged: http://www.issihosts.com/haveged/
+ - DakaRand: http://dankaminsky.com/2012/08/15/dakarand/
+ - Jytter a userspace RNG: http://www.chronox.de/
+ - CPU Jitter RNG: http://www.chronox.de/
+ - CSPRNG based on Linux, OpenBSD, Fortuna, NIST etc.
+ - NIST SP 800-90. CTR_DRBG
+ - Fortuna https://en.wikipedia.org/wiki/Fortuna_PRNG
+ - Schneier, Ferguson. No estimator needed.
+ - OpenBSD arc4random: http://www.openbsd.org/cgi-bin/man.cgi?query=arc4random&sektion=3
+ - Raw read access in test mode to collected entropy pre whitening
+ - Write access in test mode to CSPRNG
+ - No key generation etc allowed during test mode.
+
+
