Re: [Qirg] Other Security-Related Activities related to Quantum Computing...

Hello Diego and John,

I am also interested in participating in any QIRG related discussion that might take place at IETF105 in Montreal (even though there is no formal QIRG workgroup meeting scheduled).

My main interest is in the area of routing and traffic engineering for Quantum Networks, but I would be interested in keeping up to date on other topics as well.

I will be attending the IETF remotely; hence it would be nice if some sort of web conference (Google hangout, Zoom, etc.) could be set up if such a meeting does happen. I can set that up if needed.

The work is not focused on the use of Quantum-Based techniques, but to provide a way to protect our trust infrastructures (PKIs) today and in the long run. In a nutshell, we are working on two different time-horizons.

Hash-based signatures have already been standardized, however other schemes that can provide different characteristics (e.g., encryption, key exchange, etc.). Although the process has been going on for a while, it will take several more years to identify the best ones.

The approach is meant to provide (a) backward compatibility (as much as possible) for devices that, today, do not understand the new algorithms, (b) provide protection for high-value target (e.g., Root and Intermediate CAs), and (c) integrate the use of the hybrid approach to protect all parts of a PKI: not only certificates but also revocation information and provisioning services.
