RdSeed: Intel announces a forthcoming randomness generator

Intel recently announced a new instruction for randomness generation - RdSeed - to be available in future generations of Intel processors.  RdSeed is intended to be compliant with forthcoming (summer 2012) NIST Standards SP800-90B and SP800-90C.  Intel's Ivy Bridge chips, already in production, have a randomness generator RdRand, but the forthcoming instruction may be easier to use for some cryptographic purposes.  There isn't much information about RdSeed yet, but I'm looking forward to learning more from Intel in due time - it looks exciting! Here's a link to a cryptography discussion group where David Johnston of Intel recommended that we can ask questions while awaiting for further disclosures from Intel.
