Amjad, we are aware of the QC-safe work going on in CFRG. We are following it but it is very researchy at this point. We can add some text indicating that we’ll follow any CFRG/SAAG recommendations (or any security area working group’s recommendation) on using QC-safe technology.
If there is anything specific you want us to look at with IKE, please send some pointers. Thanks.
