NIST CAVP sent the email “CAVS retirement and transition to ACVTS in FY2020” to all accredited CST laboratories on 18 October 2019:
UPDATE 09 March 2020: There is a change to 5.a. below. NIST CAVP will not do any cost recovery billing for ACVTS in FY 2020. Algorithm validations using ACVTS will be free of charge until 01 October 2020.
In response to questions and requests from some of you, as well as a further review of our internal transition process, NIST CAVP have decided on the following:
Please let me know if you have questions on any of the above.
ACVTS Testing for Algorithms not Supported by CAVS
As ACVP testing continues active development, testing for Approved algorithms (i.e., security functions) that are not supported by CAVS will become available. Per (4.) above, if the ACVTS Prod server supports testing for an Approved algorithm that CAVS does not support, then any IUT that implements that Approved algorithm must be tested using ACVTS. Per (4.b.), this requirement does not override or take precedence over a current FIPS 140-2 Implementation Guidance (IG) that allows for vendor affirmation of an Approved algorithm for the purposes of FIPS 140-2 module validation.
The table below lists algorithms not supported by CAVS for which ACVP testing is available on the ACVTS Prod server. It indicates if there is a FIPS 140-2 IG that allows vendor affirmation or not.
