From 1b2782948997cf5a0d1747de13d43ba7dfa7c543 Mon Sep 17 00:00:00 2001 From: Jan Glauber Date: Mon, 5 Feb 2007 21:18:22 +0100 Subject: [S390] Support for s390 Pseudo Random Number Generator Starting with the z9 the CPU Cryptographic Assist Facility comes with an integrated Pseudo Random Number Generator. The generator creates random numbers by an algorithm similar to the ANSI X9.17 standard. The pseudo-random numbers can be accessed via a character device driver node called /dev/prandom. Similar to /dev/urandom any amount of bytes can be read from the device without blocking.
