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.

There is some work underway to make IKE that uses DH for key derivation Quantum Computer safe. Might be a good idea to consider this for lisp-crypto as well. > > Thanks, > -Amjad > > From: Amjad Inamdar (amjads) > Sent: 03 November 2015 PM 12:33 > To: 'lisp@ietf.org' > Subject: LISP NAT Traversal > > Hi, > > It will be useful if LISP NAT traversal draft (draft-ermagan-lisp-nat-traversal) can elaborate on the following > > 1) Why LISP NAT traversal cannot be accomplished without RTR (another network entity) which has implications on deployability, complexity and latency.
