I'm afraid it does not come across clear to me. So, maybe the
following pondering is relevant - or not. Basically, I'm looking at
how to integrate a FIPS-enabled OpenSSL that will be used by some
common Open Sources applications, as well as a 3rd party application
(with source code provided).
So, does your comment mean that the paying versions of Red
Hat and SuSE (proprietary) have open source applications modified to at
least include the FIPS_mode_set() call ? Why would these releases be
different in FIPS SSL 'power-up' POST checks when compared to regular
free releases ?
If I compare with GnuTLS that our product also uses, and with which it
will also go to certification, its FIPS mode is completly transparent,
with FIPS checks done on library load.
Based on the discussion in 'The I.G. 9.5 Issue', I took a look at
'Implementation Guidance for FIPS PUB 140-2 and the Cryptographic
Module Validation Program', January 15 2015 release. In section 9.10
it states:
"The power-on self-tests of the module shall be triggered from
within that library function or code block. This execution paradigm
satisfies AS09.08 and AS09.09 for a validated module."
This would make it OK for OpenSSL to automatically run the FIPS checks
when an application loads the library. Are the issues noted in the
'I.G. 9.5 Issue' still relevant ? For instance, the first paragraph
of Q4 refers to an application using the library before the library
itself has finished doing the FIPS POST checks. Hmmm. without
knowing the details I must say, it 'looks like' GnuTLS has solved this
problem - or will it simply fail certification lab testing ?
Further in the CMVP IG, there is mention that ('DEP' is a default
entry point) :
"The presence of a library DEP forces the OS loader to call the DEP
when it loads the library on behalf of the application linking it.
The DEP is executed automatically and independently of the
application code before the OS loader hands control back to the
application. The OS loader utilizes a standard mechanism for
invoking the DEP, which is agnostic of the library programming
interface and completely independent of the application code."
Wouldn't this mechanism be solving the problems raised in Q4 ?
Regards.
