Fedora EPEL 6 Update: RdRand-2.0.0-1.el6

-------------------------------------------------------------------------------- Fedora EPEL Update Notification FEDORA-EPEL-2014-1498 2014-05-25 17:02:21 -------------------------------------------------------------------------------- Name : RdRand Product : Fedora EPEL 6 Version : 2.0.0 Release : 1.el6 URL : http://github.com/BroukPytlik/RdRand Summary : Library for generating random numbers using the RdRand instruction on Intel CPUs Description : RdRand is an instruction for returning random numbers from an Intel on-chip hardware random number generator.RdRand is available in Ivy Bridge and later processors. It uses cascade construction, combining a HW RNG operating at 3Gbps with CSPRNG with all components sealed on CPU. The entropy source is a meta-stable circuit, with unpredictable behavior based on thermal noise. The entropy is fed into a 3:1 compression ratio entropy extractor (whitener) based on AES-CBC-MAC. Online statistical tests are performed at this stage and only high quality random data are used as the seed for cryptograhically secure SP800-90 AES-CTR DRBG compliant PRNG. This generator is producing maximum of 512 128-bit AES blocks before it's reseeded. According to documentation the 512 blocks is a upper limit for reseed, in practice it reseeds much more frequently. -------------------------------------------------------------------------------- Update Information: Partial rewriting, added optional AES encryption of generated values. -------------------------------------------------------------------------------- This update can be installed with the "yum" update programs. Use su -c 'yum update RdRand' at the command line. For more information, refer to "Managing Software with yum", available at http://docs.fedoraproject.org/yum/. All packages are signed with the Fedora EPEL GPG key.
