Hi QIRG, I just wanted to provide a very short summary of some of the efforts that are going on, today, and that are aimed at mitigating the (possible) factorization threats for "classic" algorithms in cryptography. 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. *For short-term solution*, the use of PSKs mixed with PublicKey cryptography provides the possibility to secure data today that is "quantum-resistant". This leaves the distribution of the PSK quite an open problem that might be solved with QKD where possible/available. *For the long term*, there are two different activities going on right now. /The first activity/ is about selecting the set of algorithms that can be proven to be secure in a post quantum-computing world. 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 second activity/ (for the long run) is how to provide hybrid infrastructures that can use "traditional" and "quantum-resistant" cryptography together. 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/. I know this is orthogonal with the work that the group has focused on so far (nothing to do with transmitting (q)-bits on the fiber or networking), however I think it might be useful for people on the list to have an overview of other quantum-related activities from the security area. /*Last but not least, I want to thank again for the organization of the workshop - unfortunately I could attend only the first half because of conflicts, but I really liked the lecture and I wanted to thank again everybody!*/ Cheers, Max -- Best Regards, Massimiliano Pala, Ph.D. OpenCA Labs Director OpenCA Logo
