Strange as it seems the *number* of cores in a processor is irrelevant to the FIPS 140-2 validation. Or perhaps not so strange when you consider that each of the multiple cores in a multi-core processor will execute the same object code in the same way (this is a case where common sense *does* apply). Likewise processor clock speed doesn't matter (FIPS 140-2 doesn't care about performance). > Also is it possible for me to get any info on whether there is any > openssl fips validation present which I can use for imx6+linux? We would all like more clarity for many aspects of FIPS 140-2. I've already shared my opinion about the equivalence of processor architectures (all ARMv7 processor with NEON being equivalent for FIPS validation purposes). You can always consult the formal scripture: http://csrc.nist.gov/groups/STM/cmvp/standards.html or ask the CMVP, the only ones able to supply authoritative answers: http://csrc.nist.gov/groups/STM/cmvp/contacts.html Or, you can sponsor formal testing of your specific platform which is the only other way to establish with absolute certainty the status of that platform. On several occasions we have done that for sponsors even when not necessary (as directly confirmed by the CMVP) to satisfy specific and unreasonable (as in "above and beyond CMVP requirements") customer expectations. -Steve M. -- Steve Marquess OpenSSL Software Foundation, Inc. 1829 Mount Ephraim Road Adamstown, MD 21710 USA +1 877 673 6775 s/b +1 301 874 2571 direct marqu...@opensslfoundation.com marqu...@openssl.com gpg/pgp key: http://openssl.com/docs/0xCE69424E.asc ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List openssl-users@openssl.org Automated List Manager majord...@openssl.org
