JFYI ----- Forwarded message from Ted Mittelstaedt ----- Date: Thu, 23 Jun 2005 22:48:51 -0700 From: Ted Mittelstaedt To: openssl-users@ Cc: Ken Goldman Subject: RE: Generating a lot of randomness... I thought that Linux's random device now supports the HRNG's for Intel, AMD and Via. Here's the docs on the Intel HRNG: http://www.linuxhq.com/kernel/v2.4/3/Documentation/i810_rng.txt What does menuconfig say? The Linux driver used to be built on the old Theodore Ts'o code, which is not sufficiently random for very high crypto. Maybe your Linux distribution still uses this code? An overview of the VIA Technologies HRNG is here: http://www.via.com.tw/en/initiatives/padlock/hardware.jsp FreeBSD 5.x has a driver for this in it's /dev/random device. An overview of the HRNG in the Intel CPU's (P3 and later) is here: http://www.cryptography.com/resources/whitepapers/IntelRNG.pdf Another very good technique is to use a simple PC cam with the lenscap on. Here's the link: http://www.lavarnd.org/what/index.html Have fun!
