On the State of PQC Migration

Publication Link!

The effort of safeguarding current and future IT from quantum computers implies more than the mere development of Post-Quantum Cryptography (PQC) algorithms. Much work in this respect is currently being conducted, making it hard to keep track of the many individual challenges and respective solutions so far identified. In consequence, it is difficult to judge, whether all (known) challenges have been sufficiently addressed; and whether suitable solutions have been provided. We present results of a literature survey and discuss discovered challenges and solutions categorized into different areas; and utilize our findings to evaluate the state of readiness for a full scale PQC migration. We use our findings as starting point to initiate an open community project in the form of a website to keep track of the ongoing efforts and the state of the art in PQC research. Thereby, we offer a single entry-point for the community into the subject reflecting the current state in a timely manner.
