I don't know the exact relationship ...Hi Alan,<br /><br />I don't know the exact relationship between X9.17 and X9.31, but no, X9.17 was never an Approved RNG. But regardless, this guidance would affect that anyway. It is now very clear that the only Approved random number generation methods will be those defined in SP800-90A. I agree with your thought that as long as the block cipher remains approved, so should the RNG utilizing it. Unfortunately, it has never really been explained why NIST is no longer considering these RNGs strong enough.<br /><br />I hope that helps.Anonymoushttps://www.blogger.com/profile/08571242151612875416noreply@blogger.comtag:blogger.com,1999:blog-3750052949981007350.post-75822137249157398802014-12-28T14:47:12.515-08:002014-12-28T14:47:12.515-08:00It seems that X9.31 is simply X9.17 using DES or 3...It seems that X9.31 is simply X9.17 using DES or 3DES as the block cipher. Was X9.17 with AES256 as the block cipher ever a FIPS 140-2 approved RNG? And does this guidance affect that? <br /><br />I would expect that as long as the block cipher remains approved, so would X9.17 using that block cipher. Unfortunately, scavenger hunting through the web of FIPS and ANSI documents has not provided clarity.Anonymoushttps://www.blogger.com/profile/18217899388487738137noreply@blogger.com
