Issue Description

The NIT has issued a technical decision for Documenting Diffie-Hellman 14 groups

Resolution

The NIT does not support the suggested rewrite since it does not clarify the issue. The term ‘how’ shall be understood in a way that the TSS should describe which DH14 groups according to RFC 3526 Section 3 are supported by the TOE. There is no need to provide implementation details of the crypto algorithms to prove the compliance. The sentence referenced in the issue section shall therefore be rephrased as follows:

If Diffie-Hellman group 14 is selected from FCS_CKM.2.1, the TSS shall affirm that the TOE implements RFC 3526 Section 3.

For further information, please see the NIT interpretation at: https://www.niap-ccevs.org/Documents_and_Guidance/ccevs/NITDecisionRfI201903.pdf

Justification
