If that note is true, then crucial details of the RDRAND specification in Intel CPUs were supplied by someone other than Intel.
Who's most likely to want to push for a particular implementation to their own enormous potential advantage? The NSA. Who has prior history of doing exactly this to a random number generator standard? The NSA. Do we know that the NSA influenced the Intel RDRAND implementation in these ways? No. Did they have both motive & opportunity? Absolutely, yes they did.
Which is why a concrete reference for that note would be good: if someone can point to the place in the public record where Intel admitted that they were not solely responsible for the RDRAND implementation then that's a fairly big deal & a brief sentence in someone's conference notes isn't good enough.
- tedunangst 13y agoObvious follow up question: who implemented rdrand for haswell? The identification of ivy bridge seems oddly specific if they're not referring to the erratum.
