-------------------------------------------------------------------------------- Fedora EPEL Update Notification FEDORA-EPEL-2022-ad612bd852 2022-02-25 16:00:26.372825 --------------------------------------------------------------------------------
Name : RdRand Product : Fedora EPEL 9 Version : 2.1.4 Release : 1.el9 URL : https://github.com/jirka-h/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 cryptographically 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.
