Dual EC DRBG Memo

[yan@mit.edu (Yan Zhu)]

This is the most recent revision of the document in which DUAL_EC_DRBG was
presented (specifically, in SP800-90A):
http://csrc.nist.gov/publications/PubsDrafts.html#SP-800-90-A%20Rev.%201,%20B,%20and%20C

Interestingly, review of this document was reopened for public comment a
few days ago "in light of recent reports."

Looks like the version that nytimes links to can be found
here<https://code.google.com/p/squeak-cc-validation/source/browse/trunk/fips/SP800-90_DRBG-June2006-final.pdf?r=3>
.

It hasn't been confirmed that Dual EC DRBG is used for anything important
in practice, AFAIK. See
